Last year my X3 had a new cylinder head gasket fitted, few months later the turbo went. The car ironically was just 3 weeks out of warranty when this happened. BMW paid half the cost of the new Turbo but not the labour, result £1k out of pocket. Yesterday the car lost power again..... Douglas Park BMW dealer in Glasgow have now informed me the EDR was blocked and the engine needs a decoke and inturn has damaged the new Turbo. Surely this should not happen so soon after having all this work done by the same dealer. Car serviced at regular intervals. I am at a loss here. Can any expert out there please advise on this. Much appreciated.

x3 decoke turbo

We are still battling with our local dealer Douglas Park, Hillington, Glasgow on this one. They are now saying BWM will meet the cost of the new turbo however we have to pay £1305 labour!!!!! Can you believe this., when I questioned this - answer 21 hours to decoke and replace the Turbo. Can anyone tell me how many hours this work should actually take. The garage have had my car now for over 1 week and I am getting more frustrated by the day. I WOULD NEVER RECOMMEND A BMW X3 TO ANYONE!!!!!! We bought BMW becuase of their reputation and reliability. 83K miles on the clock, two decokes, two turbos, cylinder head gasket........nightmare. Have also noted on this forum people say slow driving and short distances. My car is driven mainly on motorways and I do in excess of 500 miles per week.

possibly a factor, is if the carbon build up was partially accelerated due to the original failure, and while in there in the first place they didn't look! The egr valve (exhaust gas recirculation) could have been restricted by deposits for some time, and probably the inlet manifold too. This could mean the turbo, although working, is trying to shove air down a hole that is too small now. This may lead to premature turbo issues.

If the head was off previously, Personally I would have been checking other removed components. The problem may be down to one simple fact that the dealer tech's are acountable for all the time spent, and only allowed 'x' number of hours for each job, which if spent doing the main part of the work, may have meant the other parts hadn't been given proper attention.

Only an idea of course, but it could be a discussion point with the service manager who may reconsider the labour costs.

It's possibly not the car to blame, but a course of events maybe, and just the way dealt with?

Hope it gets sorted, shame to be put off a good car in this way.

Update with my x3

Do not buy an X3 unless you want to spend money on a new turbo and decoke every 6 months. We do not driver like Granpa 50mph on short distances. I do in excess of 500 miles per week, mainly motorway 70/80 mph. I only use good quality fuel - no supermarket brands and yet we still get this coking issue!!!! The car is 3 1/2 years old and when it comes back from the garage it is getting sold and I will never ever ever buy a BMW again. Potential BMW X3 buyers BEWARE !!!!!!!!!!!!

further update with my X3

Today finally got the call that my car is now fixed and fully functional. After a lot of debates with the service manager as to who was paying for this, the managing director got involved and we agreed Douglas Park / BMW would pay the bulk of the costs - we have agreed £250 towards the labour. Douglas Park have also given us a 12 month warranty on parts and labour given this is the second turbo is 7 months. How do I avoid the issue of the engine needing a further decoke in a few thousand miles. As previously mentioned i only use good quality diesel, drive approx 500 miles motorway driving 70/80mph therefore the myth of slow driving and short distances doesnt apply in this case. Thanks everyone for their answers.

i dont get how the egr cokeing up as [email protected]@ked the turbo ??? if i was them decoke the egr......if that dont cure it remove the inlet manifold and check flaps are still there and correct.....if its just lack of boost check the map sensor on back of inlet manifold this can get some crap from egr pushed in to it...this inturn stops the vnt controler from getting correct readings from the map to adjust the turbo vaines corectly ......

frustrated x3 owner sounds like you’ve had a rough time of things. There is no way an X3 of that age should have had the problems you’ve encountered, especially given the motorway use you’ve described.

I also have a 2.0d X3 of similar age that I bought from Douglas Park 6 months ago. I had to get them to sort a few fairly minor things, some covered by the AUC warranty some not. I have to say as soon as you bring up an issue they don’t like they aren’t the easiest to deal with. I really don’t envy you having to argue with them about such a costly piece of work! Glad to hear they covered the bulk of it in the end.

From various forums I get the impression that the diesel engined X3’s need a bit more TLC than the petrol ones, from what I’ve read/experienced this would be my advice....

  • Like Bmw techy says make sure you get an oil service every 10k or so.
  • You say that you use good quality diesel but I would recommend only using a premium fuel like BP Ultimate or Shell V Power. The improvement in MPG will more than outweigh the extra cost and supposedly they burn cleaner producing less carbon build up.
  • Use a quality fuel additive like Forte Advanced Formula Diesel Treatment every few months. Even if the actual benefit this brings is minimal it will make you feel better!
  • Ensure you let the engine idle for a few seconds before turning the ignition off to let the turbo cool down properly. This is very important if you’ve been on a long run as the turbo will have got very hot and if it doesn’t cool down carbon build can occur.
  • I had my local indy garage clean out the EGR valve based on advice I had seen on this forum. Yours should have been done as part of the decoke work but perhaps get this done again in a couple of years time, it’s not expensive and you can do it yourself if you are so inclined.

I did nearly 300 miles in the x3 yesterday and it left me with a huge smile on my face, great car when it’s working properly!!

2005 X3 2.0d

I have joined the forum as I have had similar problem with my wifes X3 which we have had from new and has only done 62K with FSH! I would like other owners to benefit from my experience and save themselves some money. It is used for the school run but it does have a 'blast' 4 times a week as she travels to work along a dual carriage way.

We had the engine light come on and huge loss of power and after diagnostic at a main dealer, a decoke was recommended, new DPF, etc. at a cost of £3700. I found this unacceptable and took the car to a local BMW specialist. He found some coking and a decoke will be needed at some future point, but the root of the problem was a clogged DPF.

According to this specialist, the DPF needs to regenerate periodically to clean itself. It does this by running the engine hotter by changing the air/fuel mix and energising the glowplugs (apparently) and the increased temperature exhaust gases purge the filter. Two of our glowplugs were down (not spotted by the main dealer) which would have affected the ability to regenerate, but worse, once the light comes on, the computer will not allow this regeneration so you are stuck. The specialist replaced the glowplugs and took the car out on a run and used his computer to force a regeneration. The car now drives like new and this has cost less then a tenth of what BMW wanted. There is a latent problem with this design, but there is a lot that can be done before a full decoke is required. BMW do not seem to want to fix things, just replace parts en-masse. Anyone having the same problems should shop around and save some money.

Cheers.
