    I recently received a recall noticed for this problem. Coincidently, my car is showing a wastegate fault. Do you think I would be able to get the dealer to fix the wastegate issue under this recall? Can I make the argument that this flaw caused the turbo/wastegate to fail?

    Great info…is it worth repairing the wastgate vs replacing a new turbo? What’s the cost range for repairing the wastgate vs the cost of replacing a new turbo? I’m just thinking if they repair the wastgate then the turbo craps out 10k miles down the road. Is a bad wastgate an indication the turbo is about to die?

    • You have a good point,,,,I don’t know the price of the turbo or wastegate,,,,but I can tell you the new turbo comes with a new wastegate and the labor hours to replace a turbo is 5 hours

        Thanks again for the feedback. I opted for a new turbo. I won’t incur any labor cost since they have to disassemble the turbo to fix the recall, I just have to pay for the cost of the new turbo. Do you know if I can rebuild the old turbo to serve as a backup?

      • You probably can have it rebuilt,,,,but I haven’t been able to find the parts to rebuild one yet,,,,I’m sure someone rebuilds them.

    So, it appears that BMW NA is not extending the warranty for any of the N20’s placed into X1 chassis. I am wondering if there is a difference in the install, or just in the total qty sold and then wealth of the owner that made them decide to just allow the extension for the 3 and 5 series’? I was quoted ~$5k to do the turbo and return line, only 10k miles out of warranty. Any thoughts or guidance??

    • The dealer can check and see if the problem is the turbo line or if the problem is the turbo,,,,,if the problem is the the turbo then you will replace the turbo oil feed line at the same time

    Does this intentionally leave out the N26 due to a different design or is it assumed N20/N26 are interchangeable?

    I can’t thank you enough. I just brought the car into the dealership and I think having this bulletin definitely helped. They are replacing my ’12 328i oil feed line under warranty even though the rest of the car is out of warranty.

    Hello BMWtechician! I am looking for a car for my mom, I’m thinking about buying a 2014 320i California version for her. Any problems with these car? Reliable? I want it to last at least 130,000 miles trouble free. Any input would be helpful thanks!

    • I would stay away from 2014,,,,,maybe go with a 2015 model year and a good extended warranty program so the car will be covered until 100k or what ever year it expires

        I don’t plan on buying the extended warranty. What would you say are some of the issues that make you worry?

      • Working at a dealer we mostly see low mileage cars,,,,,usually once they get to 50k mile we don’t see them again,,,,,,so I personal don’t know what happens after that,,,,,I don’t know what problems you might have.

    Do you see any problems at all before 50k?

    My 2013 X3 is throwing that white smoke at start up specially when it sits for a long time. According to the Vin # it was produced in 2012 so this bulletin should cover it. If i take it in to the dealership how would they tell if the problem is the turbo or the oil feed line? it looks like this bulletin only covers the oil feed line or does it cover the turbo as well? If they come back saying it’s the turbo, is there a way i can tell them to replace the oil feed line only (for free)? You have mentioned in another post that its about 50% chance is the oil feed line, i just done want them to tell me its the turbo($$$$) when it could very well be the oil feed line(free).

    • They should just replace the oil feed line to start with because they know it a problem and that it is covered under that bulletin.,,,I would tell them it smokes during cold start up when the car sits over night,,,,you can also video tape it on your I-phone and show the dealership that always helps

    I had a ECU tune in 2012 that was apparently noted by BMW. So when I was at the dealer recently, they denied my replacement of the oil feed line due to this modification. Is there any way I can win this argument? Obviously, BMW put out a faulty oil feed line design and I believe this problem (white smoke in exhaust) would’ve popped up even without an ECU tune. I think I’m right, but just want your feedback. I really appreciate the info here. I was able to understand the issue better… Service advisor did a really poor job explaining the issue to me.

    • You are correct your ECU tune did not cause the oil feed line to go bad,,,,the oil feed line was a bad design,,,the problem is that the dealer flagged your VIN# saying the car has been modified,,,,once that happens BMW is not responsible any more for that vehicle.,,,have you tried another dealer maybe they will take care of the oil feed line

      • I have no tips for you,,,,you just have to find someone who knows the ECU tune has nothing to do with the oil feed line

        Thanks! Also, should I have someone inspect the turbo to determine if there has been any damage from the feed oil leak? I thought I read somewhere that the leak would only cause reduced catalyst life. But in another thread I read that it could cause damage.

      • They can check the turbo when they replace the oil feed line because the turbo has to be removed anyway,,,,but you should be fine with the turbo,,,,you would have problems if there was no oil then you have a big problem.

    Just one question (for the ones who suffered the problem or you Andreas when you observed it): does the white smoke apppears even if car remains completely idle during the first (let’s say) 30 seconds after startup? I am asking because in my case i can observe that if car is started and no movement happens with it, only very few smoke appears. But this does no smell to oil but also does not appear to be clean steam. It s like steam which smells to smoke (something like when a car starts with rich mixture). If just stsrt and i move the car in the first 30 secs then the amount of smoke is bigger..so it s something strange cause does not look oil smoke but neither clean steam… Someone has experienced that? May it be the issue of oil line at the very beginning of the issue??

    ..forgot to mention..just happens when car is cold… But again..what is puzzling me is that is even that is not smelling to oil, it does no look as “pure clean steam”…and alsonis not the black smoke of a rich..that s why i wasifondering if (almost),immediate codensation is normal in this engine(it takes about 5 seconds to appear after a cold start up)
    Thanks again!!

    Thanks, Andreas for your answer!! 🙂 . I will keep an eye during the next weeks to see how is it going.. However, there is something that i really do not understand from this issue. This is: as per the info I saw, the issue is that “When the vehicle is parked overnight the engine oil pressure will equalize, this may cause engine oil to leak past the turbocharger “exhaust side” turbine seal due to carbonization of the turbocharger sealing ring. ” .. but I have some questions:
    a) if the oil moves fom engine to the exhaust side due to carbonized sealed ring, why is not happening also when engine is normally running? Should not appear a continuous smoke plume when car is driving? or in other words, why only when engine is stopped?
    b) If they mention “due to sealing ring carbonization”, Should not be the sealing ring that should be replaced and not the oil feed pipeline?
    b) The “check valve” in the new pipe, seems to correct the problem. But as i could see, it prevents the oil to be moved from the engine area to the turbo. But isn’t is this the natural way of the oil whn engin runs? (i.e. from the engine to the turbo). It would be logical for me that this situation of “preventing return to turbo” would happen in the “turbo oil return” -from turbo back to engine- pipe but what it puzzles me is the fact that it’s mentioned in the “turbo feed line” -from engine to turbo-. I have this doubt, unless my misunderstanding is related to the naming convention of the “feed” and “return” line which do the opposite way as i believe.

    Well.. i try to make myseff understandable in my questions as much as i can . hope i was able to make it .. 🙂
    thanks again!!
