I have recently brought a BMW 530d(2002) automatic with 76000 miles on the clock-I have never driven a diesel or an automatic before. The car is fantastic to drive,however on pressure on the accelerator(not neceesary full pressure) it kind of propels forwards with a sudden thrust-as if it has been given a massive push from behind.Is this how it is meant to be and represents diesel/automatic drive or is there something I need to be worried about? This never happened with the petrol cars I have drive where acceleration is a smooth and steady process.Any thoughts will be gratefully accepted.

nand,
it sounds like the turbo kicking in. If that's the case I wouldn't worry. No doubt a 530d driver wil be along in a minute to confirm or not.
Enjoy the car.

This is the effect of the turbo cutting in, subsequent to the typical 'turbo lag', as it summons up the massive torque from this engine. You'll get used to managing it and will grow to greatly appreciate it.

Thanks guys
In one of the other threads relating to the 530d engine,it was suggested to let the engine tick over after a fast motorway drive,how long should one let the engine tick over before turning the key to shut the engine.Is this also true after town/city trips.

I've got into the habit of doing it after every journey. HJ says 5 mins - me ? as long as it takes to gather my wits (longer every day I've found) and all the bits an pieces I need to take from the car.

Hi Nand
as the owner of 2 turbo cars (petrol and diesel) I recommend the following....
1. Always let the car warm up before giving it some welly. This will prolong the life of the turbo unit.
2. After mainly urban or suburban trips there is little need to 'simmer' the turbo.
3. After a fast trip and especially at service stations, always always always let the engine idle for at least one minute after coming to a halt before turning the engine off. This permits the turbo to slow down in a bath of constantly cooled and filtered oil. This 'simmering' stops the oil by the turbo cooking, carbonsing and getting generally expensive.
4. I find that after a motorway trip, the drive back home from the motorway junction of about two miles at slow speed is probably enough to simmer, but I always allow a few seconds of idle even then, once I reach home.

Espada III - well if you have a family and need a Lamborghini, what else do you drive?

BMW 3.0 litre diesels are less prone to turbo issues than the 2.0 litres. Espada's minute seems to fit in with my with gathering though. You will do a lot of "fast" trips - you won't be able to help yourself....
|
can i be cheeky and ask how much you paid for it?
and where from? roughly not the dealer, and wether it was abmw dealer or not?
full service history?
what mpg are you getting?
have you had other rear wheel drive cars?
if not, i was amazed myself at the shove in the back with rear wheel drive cars, feels like it is pushing you. rather than front wheel scrable in the fwd cars.
nice wheels (ruedas agradables)

Many Japanese import diesels have a "Turbo Timer" fitted.
These allow you to remove the keys from the ignition and lock the doors while the engine runs for a pre-set period of 30 seconds to several minutes.
Unfortunately they are not legal for use in the UK as you are not allowed to leave your car running for fear of thieves driving off in it, and must be removed before the cars are SVA'd.
Many though are re-fitted and help prolong the life of the turbo.

thanks guys for some very sound advice
in response to vtiredeyes question-I bought the 530d from an independant bmw specialist dealer in cambridgeshire(local to me).It had 76500 miles on the clock and had full local bmw service history.It is a jan 2002 registered automatic with full leather,cd changer,comfort electric seats/steering including memory and 1 yr warranty(which is also supposed to include catalytic convertor).The other bits like metallic paint,rain sensor,automatic headlight activation etc comes as standard on this car,I think.One of the cup holder is broken,and some stonechips which were touched up.I am not sure how many mpg i am getting at this point as I have had it only for 3 days.i bought it for £15,000

has he got one of the same but a manual?
i would be most interested......
can travel to cambridge np.
|
No I don't think so.He had a 530i which I test drove,but that was an autobox as well and got sold next day.I think he has a 1998 528 touring with a lot of specs for about 7000 and 134k on the clock.

also on reflecting on all the sound advice given,the car I bought was a lease car driven by one person.If he never heeded the advice re letting the engine tick over,would that have caused any damage to the engine and if so how does one know? I presume having done about 25000 miles/yr on average-those must have been fast motorway miles!
|
|
If its any consolation - my last few cars have been leased (including my much loved 330 and 530ds) I treated them like my own total TLC. The 330d is still with the extended family and has been totally faultless apart from a misbehaving radio of late.

Some modern high performance turbodiesels have watercooled centre bearings so thsi is no longer applicable, I have no idea whetehr this is true of the 530D, but worth investigating if you own one.
