BMW 5 Series (2003 – 2010) Review
BMW 5 Series (2003 – 2010) At A Glance
BMW is known for building high quality cars that are great to drive and this is perfectly evident in the BMW 5 Series. It really is superb on the road with keen handling and great composure in bends, making it the really involving to drive. But the BMW 5 Series isn't just about handling, it also has good green credentials and thanks to Efficient Dynamics (the programme of efficiency technology introduced in 2007), offers some very economical engines.
The most popular is the 520d - and engine which belies its small size to provide impressive performance but with great economy of 47.8mpg. Of course if you want performance there's no shortage of choice either with the punchy 535d and sublime 535i the stand-out choices in the range.
And this sporty feel is always evident behind the wheel with an agile and composed feel, especially evident on twisting roads. Of course there is a downside to this - the firm ride. Standard models are acceptable, but those with stiffer and lower suspension, such as the M Sport cars with their larger wheels, can be crashy over rough roads and bumps.
But this doesn't detract from the superb build quality, spacious cabin and modern interior of the BMW 5 Series which is why it's such a popular upmarket saloon and one that's very highly rated by its owners.
BMW 5 Series (2003 – 2010) handling and engines
- Engines range from 520d to 550i
- Readers report Real MPG to be between 17–55 mpg
Second is good for just on 60 on the clock, but you hit the limiter almost immediately afterwards. The fly by wire throttle feels unresponsive if you ask too much of the engine/body combination. It's a big, heavy car with not a lot of torque. But, as they say, familiarity breeds content and as you get used to the clutch, gearchange and throttle action you start to feel pleasure from getting it right rather than irritation at getting it wrong.
The steering is sublime: the perfect reminder that's how steering can be when you're not steering driven wheels. The ride quality on the standard 225/55 R16 tyres is superb, soaking up potholes and traffic-harming measures almost as well as a balloon-tyred 4x4. Handling is fine, with plenty of grip and all the information you need fed directly back to you through the steering wheel. (Remember that before you order huge alloys with painted on strips of rubber instead of tyres.) It's very comfortable once you've got to grips with a seat adjustment that curiously marries electric height and backrest rake adjustment with manual fore and aft and a simple lock on the rocking squab.
The standard seats are upholstered in very nice cloth, a bit akin to posh office chairs or perhaps something out of a G Plan catalogue. To my mind, much better than leather.
You're confronted with what you can see of a conventional instrument cluster, but bits of it can easily be obscured by adjusting the wheel to the height and reach that suits you best.
The I-Drive system is frustrating at first, but you soon fall into its quirks, a bit like a Mac computer (Macs used to be intuitive, but aren't any more). The radio reception is top quality. But the best bit is the expensive optional pictographic park-distance control which is both accurate and exceptionally clear (see the photo). The satnav is intuitive and so quick and easy to use you could conceivably set it on the move without being distracted. Its instructions are clear, precise and visually big so there's not much chance of taking a wrong turn.
The indicators take a bit of getting used to, because they're the new switch type and you have to switch them fully otherwise they don't easily cancel. There are no irritating gongs reminding you that you forgot to put on your seatbelt. And the ‘lights-on' or ice warning sound is the most soothing I've ever heard. What I'm trying to get to is that this isn't a mass of high technology arrogantly flung at you on a take-it-or-leave-it basis. A lot of thought has gone into almost every aspect of the car to surprise, delight and warm you to it.
Should you go for it instead of an E Class, or a Jaguar S Type? Well, perhaps not the 520i. The extra £1,400 for the greater power and torque of the 525i has to be money very well spent. That said, smaller six cylinder engines are much smoother than the supercharged four and the 2.6 litre six in the Merc. And the BMW is better value for money than the 2.5 litre Jag V6.
Upscale, the fight against the W211 E Class gets harder. And I still reckon the E 320 CDI estate is the best station wagon in the world. If you had £35k and could only have one car, then that would be the car to have.
But in £25k territory, with introductory discounts available, the 520i and 525i make an excellent account of themselves. And, believe me, the looks will grow on you.

For a start, I haven't driven a car with so much headroom since the Citroen Berlingo. In the new 5-Series I felt like a dwarf. And 5' 9" used to be an average sort of height. The back seat is just as good, with such huge head and legroom it makes some other cars (W211 E Class included) seem cramped in comparison.
The boot is vast and well-shaped, only creating a bit of lower spine worry because of its length. Yet I still managed to dispose of a few thousand magazines that had been choking my office without suffering what back-quacks term ‘disc involvement'.
And it's quiet. The E39 has low wind noise, but the E60 is almost eerie. All the better to hear the joyful whooping yowl of its beautifully smooth 170bhp straight-six engine.

September 2003
Launched in the UK with 2.2 litre 520i SE, 530i SE and 530d. Followed in October 2003 by 525i SE and 545i SE. Upgraded 218bhp 3.0 diesel engine from launch.
Engine line up originally to include FSI direct injected petrol 2.0 Valvetronic four; 2.7 and 3.0 sixes, 3.6 and 4.4 V8s, and M47 2.0, M57 2.5 and M57 3.0 litre diesels. 6 speed manual or 6 speed ZF autoboxes. Optional 'Active Steering' which works in conjunction with ESP stability system to help keep the car under control in emergencies.
Performance Figures:
520i 170bhp, 155 lb ft torque, 0-60 8.7 secs, top speed 143mph; mpg 31.4;
525i 192bhp, 181 lb ft torque, 0-60 7.7 seconds, top speed 148mph, mpg 30.1 combined;
530i 231bhp, 221 lb ft torque, 0-60 6.6 seconds; top sped 155mph; mpg 29.7; 530d 218bhp; 368 lb ft torque; 0-60 6.8 seconds; top speed 151mph; mpg 40.9; 545i 333bhp, 332lb ft torque, 0-60 5.6 seconds, top speed 155mph (limited), mpg 25.9 combined.
October 2004
535d in UK from October 2004. EU4 compliant. 272bhp and 560Nm of torque from sequential twin turbo 3.0 six with small turbo giving maximum performance from idle to low engine speeds – 500Nm of torque at 1,500rpm, then, as the revs build, a larger turbo helps to further compress the air for a second, seamless boost of power. The result is a continuous surge of acceleration making for a zero to 62mph time of 6.5 seconds yet a combined fuel consumption 35.3mpg.
January 2005
Optional 'Head up' display projected onto windscreen announced January 2005. Big, deep boot with well for a spare wheel underneath even if the car is running on runflats. New magnesium-aluminium N52 composite engines designated 523i, 525i and 530i from Spring 2005 replaced previous M56 6-cylinder engines.
August 2005
520d from August 2005 has 163bhp, 340Nm torque. 0-60 8.3, top speed 139, 47.9mpg combined. CO2 low 158g/km good for BIK. 540i and 550i from September 2005. For 2006 model year, 170bhp 2.2 litre 520i replaced by 174bhp 2.5 litre 523i
April 2007
Range refreshed
Facelifted cars have single under-bumper aperture with single horizontal bar across it and reshaped spoiler boot lid like M5. New, more efficient 6-speed automatic transmission. 'Brake Energy Regeneration' and AGM battery only recharges on engine over-run saving 3% CO2. 530i M-Sport auto now 271bhp and does 37.7mpg combined emitting 178g/km.
September 2007
520d got Efficient Dynamics N47 2.0 diesel engine with the timing chain at the back and power increased from 163hp to 177hp. 0 to 60mph down to 8.0 seconds in the Saloon compared to 8.3 seconds previously. Combined figure now 55.4mpg. CO2 136g/km sees 520d drop into Band C VED. Now with EfficientDynamics technology including Brake Energy Regeneration, active aerodynamics, Optimum gear shift indicator and low rolling resistance tyres. M57 3.0 litre replaced by N47 3.0 litre diesel.
January 2009
Business Edition models launched January 2009. Offered on 520d, 525d and 530d Saloon and Touring variants, and in SE and M Sport trims, the Business Edition comes with Dakota leather, Bluetooth, BMW Business Navigation system and a six-disc CD changer.
For a premium of £1,750 over a standard 525d or 530d SE or M Sport model, Business Edition vehicles receive the same upgrades as the 520d Business Edition models with the addition of a BMW Professional Multimedia Navigation system, Extended voice control and a USB audio interface in place of the six-disc CD changer. M Sport Business Edition models powered by either the 525d or 530d gain 19-inch M Double-spoke alloy wheels.
What to watch out for
Check front screen for stress fractures. Very thin windscreen glass cracks easily when hit by stones.
Check runflat tyres, especially if Dunlops. Problem of cracking of sidewalls due to a fault with the tyres. Dunlop compensates according to the mileage the tyres have done. Tyre roar can become significant on runflats after around 15,000 miles.
General Warning about Automatic Transmissions: Many BMWs have "sealed for life" automatic transmissions. Regardless of whether you have a full BMW service history, the dealer will never change the auto fluid. Many of these boxes are failing around the 120-150k mark - often well outside of warranty and to a cost of £3.5k plus VAT. A good independent or automatic transmission specialist can and will change the fluid for you (and any good BMW independents will recommend this anyway). This is commonplace in the US and means the 'box should last the life of the car rather than being the cause of it being written off. General advice is ensure the fluid is flushed out every 60k or more preferably at each Inspection II.
One reader reported a problem of corrosion of suspension parts wearing the bushes and requiring £1,000 of rectification work (done under warranty). But as these models come out of warranty, this could become an issue and is unlikely to be covered by an aftermarket warranty.
One report of "squeaking" driver and front passenger side windows on a 2005 car. This can be eliminated simply by polishing the painted metal part of the door aperture.
One report of double turbo failure on 535d after 50k miles.
Report of flat spots and poor acceleration from N53 174bhp '523i' engine (introduced Spring 2005), even when run on Shell V-Power. Further report of flat spots in power deliver of 2006 build 525i.
Injectors failing regularly on N53 'Efficient Dynamics' 6 cylinder engines. Thread about this on E60 Forum.
N53 revised version 6 cylinder 525i petrol with Valvetronic can suffer bore ovalisation at moderately high mileage (90k) due to dribbling injectors. Oil consumption can rise to 500 miles a litre. Only remedy is a new short engine.
Check PAS fluid level regularly. Steering rack may leak fluid unnoticed out of end seal and into track rod end gaiter. Seems to be a Europe-wide shortage of parts to correct this.
On all 2003/2004 diesels, 4 and 6 cylinder, intake manifold swirl actuators can break off and be ingested by the engine, wrecking it to the tune of as much as £12,000. However, in some cases (one of a 2004 530d to which this happened in 2009), BMW fitted a new engine at a customer cost of £2,000. One school of though says that swirl flaps can be discarded entirely, though this will make the engine less efficient. The first sign of an impending problem with the swirl flaps is very poor idling. www.pmwltd.co.uk has a solution, which is a billet aluminium blanking plate that is substituted for the swirl flap. Well worth doing because it could save the cost of a new engine or having to scrap the car. More also at www.bmwswirlflaps.co.uk
Repeated failures of ZF autobox in 231bhp 3.0D symptomised by clunks when moving from P to R or N. Has necessitated new transmissions.
06-05-2011:DPFs and cat converters tend to need replacing at 120,000 - 130,000 miles. Cost is £1,500 - £2,000.
06-05-2011:Some cases of brake pipe corrosion on cars just 6 years old.
24-10-2011:Starting problems with 530D may be caused by failure of camshaft positioning sensor fitted to the top of the engine and fairly easy to get to.
10-12-2011:Diesel Particulate Filter problems and consequent turbo problems increasingly common on 320ds repeatedly driven shorte distances from cold.
29-12-2011:One report of i-Drive failure on a 525D 3 years 6 months oldf. BMW contributed 50% of the parts cost, so the bill was £765.
05-01-2012:Warning about transmission sump pan failures leading to oil leaks, but reader unspecific about model and whether manual or automatic.
19-01-2012:On 520d, damped 'dual mass' auxiliary belt crankshaft pulley can eventually fail.
03-02-2012:Significant numbers of high pressure fuel pump failures on 530i and 5 35i in the USA. See link: www.n54tech.com/forums/showthread.php?t=14650 BMW initially "blamed" "ethanol" or "poor quality" gasoline in the U.S. for these failures. In fact, BMW HPFP failures are well documented in Germany (even with their "superior quality" gasoline), Australia, Asia, South Africa, etc. Some of these countries have never used ethanol in any of their gasoline..... HPFP Part Numbers 1. 13-51-7-537-320 2. 13-51-7-585-655 3. 13-51-7-592-881 4. 13-51-7-596-123 5. 13-51-7-594-943 6. 13-51-7-613-933 7. XX-XX-X-XXX-402 8. 13-51-7-616-170 9. 13-51-7-616-446.
05-02-2012:DPF failures now quite common on diesels at between 80,000 and 120,000 miles. Any sign of a problem, do not continue to drive the car because increased back pressure can stop the turbo turning, leading to overheating and seizing of the bearing.
11-02-2012:Timing chain failures becoming increasingly common on N47 2.0 litre diesel engines subject to extended oil change regimes. Can occur from about 5 years old and from about 90k miles. From 50k miles onwards, best to change the oil every 10k miles maximum.
16-06-2012:Coil and injector problems persist. One 2007 E60 525i has had 17 fuel injectors since new (including the original 6), 2 NOX sensors and coils replaced and re-coded twice due to original software problem causing coils to fail. (BMW dealer from whom car was purchased NEW say's he'd had dozens of cars with similar problems.)
10-08-2012:Low power from the battery caused by a poor connection (rectified by the battery cable recall) leads to false readings on the instrument panel, from: Warning AutoTransmission failure, to almost every other bogus message, including reversing light failure. Could also cause the engine to cut out. This should be rectified by the recall work, but the fault readings in the ECU also need to be cleared.
31-08-2012:Ridiculous design problem of electronic control unit that sits in styrofoam under the spare wheel where it is vulnerable to water ingress to the trunk. Explanation here (warning contains bad language and material of an offensive nature: it's a of a German rant): http://www.liveleak.com/view?i=af8_1346299893 (see recall news).
16-12-2012:Apparently the drains from the rear doors can silt up, the doors fill with water and cause an electrical problem that drains the battery.
17-11-2013:DPF failure reported on 2007 525d (3.0) M-Sport driven 9,000 miles a year with a daily 30 mile commute.
16-12-2013:BMW dealer reported rusted brake pipes on 57k mile 525i and quoted £1,247 to replace them.
04-01-2014:E60/61 petrol models can develop electrical failure in three different areas simultaneously: fan blower in the cabin; mirror demisters and rear window demister. This can be solved by simply unclipping the 'Intelligent Battery Controller' cable connected to the battery, then reconnecting. It's part of the problem listed above at 10-8-2012 and 31-8-2012.
09-01-2014:Rear suspension arm balljoint failure on 120k mile E61 525i Touring leading to collapse of nearside rear suspension. From the photo it looks like a wear and tear problem that should have been picked up in the car's last MoT. May have been due to the weight of loads carried.
10-01-2014:Fault with high pressure fuel pump of petrol models can lead to stalling without warning and does not show up on BMW diagnostics. This led to a voluntary recall on 26-10-2010 on 2007-2010 5-Series E60s and E61s in the USA so is an acknowledged fault, but no recall in the UK.
13-01-2014:Failed turbo in 61k mile 2010 E61 520d auto, probably due to failure to idle from super-hot. BMW generously offered £1,000 towards £1,800 replacement bill. This same failure is common in E83 X1 2.0 litre diesels.
15-04-2014:Worldwide recall of 489,000 BMW cars with six-cylinder 2.5 and 3.0 litre petrol engines of which less than 3,000 are in the UK. These are: N51 (1991-1995), N52 (from 2005) and the N55 6-cylinder petrol turbo (from 2009). The screws for the housing of the adjustment unit of the variable camshaft timing (Vanos) for the intake and exhaust camshafts could potentially become loose or break. An engine warning lamp ‘should ’ appear in such circumstances, but if drivers experience any loss of power they should contact their BMW dealer immediately.
10-05-2015:Turbo failed on 75k mile 2009 E60 520d M Sport costing £1,795 to replace, then the vulnerable rear wiring looms in the trunk failed costing a further £789.
27-07-2015:Problem of tramlining and poor ride comfort of 2004 525i E60 overcome by fitting Bridgestone S001 Run Flat 225/50 WR/17s in place of Bridgestone RE50 Run Flat 225/50 WR/17s. It turns out that the Bridgestone Runflat 3s we tested in June 2009 (that were supposed to come to market by December 2009) were actually delayed until March 2011. Bridgestone commented that the original tyres fitted to this 525i must have been 'Runflat 2' 225/50 R17 94W RE050 RFT (IPC: 77546) and that they were replaced by 'Runflat 3' 225/50 R17 S001 94W RFT (IPC: 4955) which is 3rd gen RF Technology. But IPC: 4955 (S001) is OE for the BMW 3 series and not 5 series. The spec in question, utilises 3rd gen RF Technology but does not utilise sidewall cooling fins in its design. Not all S001 utilise the full 3rd gen RF Technology package (case by case / depends upon need). So the reason the end user has improved ride and tram lining performance is due in part to 3rd gen RF Technology. However, the spec in question was not specifically developed for his vehicle, so other areas of performance (steering response, weight on centre, etc…) could be not in line with the original OEM vehicle DNA.
01-11-2015:Radio crackling on an E60 5-Series where the radio aerial is embedded in the rear window glass might be because the earth strap from the trunk lit to the car has snapped. Peplacing the strap stops the crackling.
16-11-2015:If satnav fails and BWW dealer wants £1,600 to replace it, the failure may only be the laser disc reader and a specialist can fix this for £250.
13-12-2015:Problems reported with DPF of 2007/57 BMW E60 520D driven 14,000 miles per year, 80% in heavy traffic (A406).
11-02-2016:Report of transmission clonking on 65k mile 2003 BMW 530 that had never had its transmission fluid changed.
28-07-2016:Report of 2009 E61 BMW 525d Touring auto suffering 'electrical failure in unidentified module' (at the bottom of the boot). Owner quoted £8k plus VAT to fix. Insurers declined to pay out. Inspector found that the module was "like a lump of carbon". This seems to be related to 31-8-2012 and Official Recall R/2012/039: of 24-5-2012 (details in the Recalls section, next page).
20-09-2016:Reader reported total electrical failure of his 2009 BMW 525D. Insurance Assessor's report: "The vehicle suffered an electrical failure of an unidentified module mounted in the vehicle's boot. Thius caused an electrical short circuit, causing the earth wire in the body wiring loom to heat up. This has melted the plastic insulation of the earth wire and adjacent wires." Total repair cost estimated at £10,414.28. (See E60 entry 31-8-2012 for an hilarious account (some swearing) of a ridiculous design deficiency of E60/E61 5-Series whereby the battery is sited directly beneath the one-way rear cabin vent flap so if the one way flap fails water is forced through it onto the battery: http://www.liveleak.com/view?i=af8_1346299893. There was a recall: R/2012/039: http://www.vosa.gov.uk/vosa/apps/recalls/searches/expand.asp?uniqueID=39ADAE6B50B53351802579CA0037A982&freeText=Blank&tx=/)
28-03-2017:On a 2006 BMW 530d the digital clock stopped randomly and access to the service checks became barred. The reason turned out to be that the ECU had been programmed to remember when the car's MoT was due and it was overdue so this was the warning.
17-06-2017:Report that if a BMW E-60 5-Series is not regularly used and if both rechargeable keys are not regularly used they lose their capacity to hold a charge and the only way to replace them is to buy new ones from BMW dealers at £170 each. (The rechargeble batteries in the keys are charged when the key is in the key socket in the car.)
04-04-2018:Report that wiring fault in rear light clusters of BMW E60 5-Series is still being fixed FoC by BMW dealers: "I've been having random warning messages from the car computer screen telling me that various rear bulbs were faulty, but on checking, found them all to be okay. It appears that my car has been another victim of the widespread and well reported bad earth connection into the rear left module, where the connections and wires get basically "fried" as the earth connection is inadequate to carry the load. Apparently, this resulted in a quality enhancement that VOSA enforced with BMW and they were told that in the interest of safety, this should be advised to all UK dealers and owners. When I contacted my local BMW Dealer they then arranged for me to take the car in and have the rear light clusters replaced free of charge." The reg of this car is CX10 VKJ and VIN: 530D SE E60WBANX32020C042424
26-06-2018:Report of 2009 BMW 520D SE Business Edition (N46 diesel) exploding with a sudden loss of power at 90,000 miles after a brief period of a strange tiny whining noise when pressing the accelerator pedal (driving at 65-75mph). BMW dealer diagnosed of a blown turbo, air cooler for the turbo and diesel particulate filter. Suggest replacement of these parts will cost £1,650 (turbo), £690 (DPF), £350 (cooler) with total labour of £400 plus VAT resulting in a total of £3,700. The most likely reason for this is that the turbo bearing oil feed and oil return pipes became blocked with carbon from shutting off the engine too often when the turbo was very hot. The effect increases exponentially as the pipes become more restricted with carbon, cutting off the oil supply to the turbo bearing that then gets red hot because it isn't being cooled by oil flow. So the first thing to be absolutely sure about is that the turbo oil feed and oil return pipes are replaced at the same time as everything else. A cheap job that cuts corners could prove to be very expensive.
26-08-2019:Report of electrical problems with 2006 BMW 525d. " Last month I was driving at night when, without warning, there was a pulsating loss of electrical power, with the headlights flashing off and on, speedo dropping to zero and then recovering, radio going off and on, loss of display, also off and on, and any manner of warnings on the display appearing such as transmission, ABS, flat tyre monitor, and the car going totally dark in between these pulsating events. Later, the car behaved absolutely normally and the check button gave “check OK”, “no faults”. Some days later I took the car to my local BMW dealer, who looked rather puzzled. But as the AGM battery was six years old I asked them to put in a new one. Also, there had just been a recall for this car due to possible poor earth connection to bodywork of the battery cable. This was also checked out while the battery was being replaced. The BMW service manager told me afterwards the OBM had recorded a battery short circuit. All this reassured me. So I left them quite happy in the believe that all my problems here had been solved. But today as I was driving slowly through the high street the problem reoccurred. First the radio and display disappeared and repeatedly came back, I noticed the speedo drop to zero a couple of times, and then the big display warnings came, this time ABS and Flat Tyre Monitor not working. I continued driving. Shortly afterwards everything was OK once more, but then the same problem came back again a little while later." Same issue as reported 20-9-2016 and 4-4-2018.
