BMW 4 Series Convertible - Shall I/Shan't I? New BMW - pinheadplanet

I went to see a 420d Convertible and noticed a water sound sloshing around just as I parked up the car after the test drive yet still agreed to buy the car as I didn't know what it was. Now on searching google for a while it seems water ingress is a problem with BMWs.They retain water somewhere.

I don't know how long that water has been inside the frame or wherever it is and what scope there is for it have created some corrosion.

The dealer said they are going to look at it, but the the question is do I still go ahead with the purchase? Maybe the dealer will only drain the water and won't resolve the issue of it retaining water permanently so it just happens again once in my ownership.

What to do? Anyone with experience of this?

My 10p worth is this: if it's a BMW Approved Used car from a main BMW dealer, it's probably worth going ahead. My son bought a 4-series Gran Coupe a few months back under the Approved Used scheme and the dealer aftercare is good - they sorted out some niggles which emerged without fuss (broken catalyst matrix, investigating squeaky suspension).

If it is NOT under the BMW Approved Used scheme, I wouldn't touch it with a 10-foot electric cattle prod.

I think I would swerve this car . This is a known and common problem . Dealer may be able to fix the problem ,but what issues has it left behind. My friend has a similar car ,and he first noticed that the radio went dead. The amplifier gets swamped by the water. He was quoted a 4 figure sum to fix it ,if there was no contribution from Bmw.

I too wouldn't bother, my opinion it's beyond ridiculous that such an expensive car has this apparently common problem.

BMW 4 Series Convertible - Shall I/Shan't I? New BMW - nellyjak

As above...why risk it.?...I'd walk away.

Dealer told me the warranty will only cover new issues and not existing issues when the car is sold.

Thankfully he couldn't make his attitude any more plain, immediately trying to weasel out of his (dealer's) responsibilities before he's even got your money in his greedy mitt, or did he confirm that anything currently wrong with the car is down to him?

GB, it is not "weaseling", it is a matter of law. The responsibility for a pre-existing defect lies with the dealer, not the warranty company.

Then walk away as fast as you can. The dealer is ignorant of its legal responsibilities and obviously has no regard for its customers.

As HJ repeatedly states on here, any fault that occurs within six months of you buying a car is assumed to have been present at the time of purchase - so the dealer is obliged to fix it at no cost to you.

But if this dealer is already taking a dismissive position, which means you'd have a load of hassle. Just leave it and find another car.

Sounds like potential headaches with this car. Walk away.

OK bit of an update as just heard from the dealer.

They are stating that all issues that are current with the vehicle are their responsibility and will repair them prior to the car being sold and he has assured me that they are being permanently repaired so any future issues they have a responsibility to sort. In all honesty he said everything you want to hear for your own reassurance, so I can't fault them for that . He even stated that BMW know about the issue and have issued a repair procedure but not gone as far as a recall.

It all seem legit to me so I'm going ahead. They even a replacing an interior trim panel that I hadn't noticed was damaged until I got home and viewed the pics online again.

Nothing to stop the OP sending the dealer a summary of the discussion.

If I were the owner of a car dealership I would find the above discourse, and final result, most reassuring.

The OP has taken a drive in it and noticed the sound of water sloshing about.

It transpires that the issue is an acknowledged one and there follows much debate about who will and who won't fix it.

It even turns out that BMW know about it but haven't finalised an official fix for it.

And still the OP goes ahead and buys it, despite all the implications that a known issue concerning water ingress may hold.

Bliss! Imagine all customers were that gullible.

BMW 4 Series Convertible - Shall I/Shan't I? New BMW - Andrew-T

I would guess that the dealer might treat the problem as far as releasing the water and cleaning up, but maybe not as far as preventing a recurrence. Perhaps I am too pessimistic.

BMW have finalised the official fix for it, it is getting permanently repaired. The dealer has always said they are going to repair it and there's never been any debate about who will fix it.

"The dealer said they are going to look at it, but the the question is do I still go ahead with the purchase? Maybe the dealer will only drain the water and won't resolve the issue of it retaining water permanently so it just happens again once in my ownership."

I think you've answered your own question. The dealer will do as little as possible within their legal obligations.

I suggest you cancel this one and look again. Go for a diesel only if you do at least 15,000 miles a year; otherwise look for a petrol. I believe the six-cylinder petrol engines are more reliable than the fours (and more fun); both are more reliable than the diesels.

Why only if I do 15k miles? Aren't the diesels more economical all the time?

In a word, reliability. if you peruse the relevant reviews for BMW's, not just the 4 series, but the whole range, you will find that far from being the paragon of German excellence, they are actually not that reliable. And the main culprit seems to be the 4 cyl diesel followed by the 4 cyl petrol models.

In addition to that, with the diesel engine (and this is the case with most modern diesel engines, not just BMW), they need to do a proper amount of mileage to keep the emissions equipment working properly. If you do mainly short, stop start town journeys, this will inevitably lead to an expensive failure which BMW won't help you with. So buying a diesel if you don't do the kind of mileage mentioned, is a false economy. If/when, the failure i mention happens, it will cost a lot more than the fuel you save over a (more reliable) 6 cyl petrol.

But hey ho, it's your money.

<< Why only if I do 15k miles? Aren't the diesels more economical all the time? >>

Plus the fact that diesel fuel costs several p/litre more than petrol, diesel cars cost more initially, and some may now depreciate faster since they have got a bad name for toxic emissions. It may take 15K/year saving in MPG to offset these other effects.

OP. Please let us know who is selling this car, the age, mileage and the price. How does this compare with a main dealer vehicle of similar specification?

Why on earth would anyone consider buying a car that had enough water sloshing about one could hear it??

I do find some threads confusing, the op comes here asking for opinions , gets told to walk away then announces he's buying it......

You and me both!. There have been quite a few instances recently of folk who have already bought, or agreed to buy a car with faults, coming on the forum asking for advice. Don't really understand this (especially if the fault in question is something the car is known for), do your research for any known issues before deciding what to buy. If the car currently has a fault, don't agree to buying it (signing anything, paying deposit, etc) until such times as the fault is fixed.

I do hope the car in this case doesn't turn out to be a lemon, but.........

Hi All,

Some very valid points raised here and I appreciate all your input even if I may have thought about things in a way which may seem difficult to understand, so here's a little bit of my reasoning:

Let's face it every car at some point or another is going to have an issue during our ownership and we are going to get it fixed and carry on, it's the same with this car, it's had an issue but it's fixed and now it'll carry on. All cars are going to be like this unless you buy a Nissan or something Japanese, or so I would have thought anyway, however I have just been reading that the Qashqai has terrible problems with the DPF, so hey, each and every car is susceptible. And anyway I'm not buying a car solely on it's reliability factor, I doubt many of you guys and girls on here do so either.

The decision to buy comes from what the car is, a hard top convertible. I don't like the noise of the soft tops, that's not what I'm after. It would be great if Mercedes did a hardtop but they don't.

This car is not more expensive than a petrol version. It's a '65 plate 420d with 26k miles and costs £16500 after negotiation. It has all the extras you would want, HK, Aircollar, Heated Stearing Wheel, Sports auto box. It is from a Main Dealer and very rarely do they come up at this age with this mileage with these extras at this price.

I'm taking a chance, I know that and In truth I don't feel great about it, but the alternative would be to buy a car that I didn't particularly want ie a Saloon. I might not keep it for a long time, let's see, it's certainly going to be a while until I can use it with the roof down, which essentially is the main reason for getting it.

At the end of the day we are all different and will all make decisions based on our own criteria, that's why we've all got different cars and why we all have different opinions on here, as I say I do appreciate the input, it is helpful even if I have done the opposite of what you have suggested.

PS - I hope it's a not a f lemon either :-)

I'd pass it by. BMW's are such a common car on our roads these days. Ten a penny. There's a better example bound to be just around the next corner. Ditto Mercs etc.

BMW 4 Series Convertible - Shall I/Shan't I? New BMW - pinheadplanet

There's a better example bound to be just around the next corner.

But how would you know if that car had the problem previously and had the fix? You wouldn't would you, so that my point. It surely has to be some degree of chance when you're buying a car.

Is the car under the BMW Approved Used scheme? If it is, you do get decent warranty etc.

If it isn't, my 10p's worth is to leave it and go for one that is Approved Used. A quick search on BMW's site shows 12 Approved Used 420d convertibles under £18,000, and many more if you spend a little more. There's plenty of choice out there.

Let's face it every car at some point or another is going to have an issue during our ownership

That is highly debatable, but i guess it depends on what you are willing to put up with for the image.

I have just been reading that the Qashqai has terrible problems with the DPF, so hey, each and every car is susceptible

Nissan is owned by, and uses, Renault running gear and platforms, hence not very stellar reliability (whether petrol or diesel).

The decision to buy comes from what the car is, a hard top convertible. I don't like the noise of the soft tops, that's not what I'm after. It would be great if Mercedes did a hardtop but they don't.

I would have thought that a modern quality soft top would be no more noisy than a hard top, at least at legal speeds (this was certainly the case with the 2003 Saab 9-3 convertible i used for a few days about 10 years ago). And i'm pretty sure that is the reason Mercedes no longer does them (that and the fact that folding metal hard tops are less reliable and much trickier to fix if they go wrong).

This car is not more expensive than a petrol version. It's a '65 plate 420d with 26k miles and costs £16500 after negotiation. It has all the extras you would want, HK, Aircollar, Heated Stearing Wheel, Sports auto box. It is from a Main Dealer and very rarely do they come up at this age with this mileage with these extras at this price.

The reason for this is almost certainly due to diesel falling out of favour with the buying public in general (rightly or wrongly), and actually brings up another point, that of future resale value. If diesel continues to become less desirable you could end up losing a lot of money come trade-in time. As for the "extras", not sure what HK is, but my MIL's Hyundai i10 has a heated steering wheel and most auto's from the last 20 years will have a sport mode (including my wife's Honda Jazz).

I'm taking a chance, I know that and In truth I don't feel great about it, but the alternative would be to buy a car that I didn't particularly want ie a Saloon. I might not keep it for a long time, let's see, it's certainly going to be a while until I can use it with the roof down, which essentially is the main reason for getting it.

If you are not feeling great about this purchase, then surely you should listen to your instinct. This is what used to be referred to as 'gut instinct' and back in the days of the hunter gatherer, could well save your life!. I know, i know, completely different context and potential risk!. But you shouldn't ignore your own misgivings.

At the end of the day we are all different and will all make decisions based on our own criteria, that's why we've all got different cars and why we all have different opinions on here, as I say I do appreciate the input, it is helpful even if I have done the opposite of what you have suggested.

Indeed we are, so i wish you the best of luck with it and hope the car proves us wrong!.

"I'm taking a chance, I know that and In truth I don't feel great about it...."

Well you should! Buying a car is one of the most expensive purchases people make, and feeling good about it should be part of the process, particularly if it's something like a BMW and not just a means of getting from A to B.

Note what Craig said above - there are plenty more out there - even more if, as some of us suggest, you look at petrol engines too. There's also the 3-series convertible (previously 1-series) which isn't much smaller. Find one that you do feel good about, and enjoy.

For the record, I've had two soft-top BMW convertibles as fun cars, a Z3 and a 125i, both bought at seven years old. Neither of them leaked, nor generated any more wind noise than would a saloon.
