    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?

    • That’s going to really hard to prove that the wastegate and turbo oil line are related

        OK. Thanks. I BTW, I love this site, keep up the good work. One more question, is it possible to repair athe wastegate without replacing the turbo?

        Like

      • Yes you can replace the wastegate separately,,,,you either have vacuum wastegate or you have a electric wastegate

      Recently (July 2018) our BMW dealer had to change the turbo oil feed line of our BMW 520i (2012 with 82.000 kilometers), due to extreme smoke coming out of the exhaust pipe during cold start after sitting more than one days. We’ve confronted BMW Group (Netherlands) with the documentation on this website and particularly with the extended warranty document (see the posting on this website on August 2, 2018) .
      BMW Group replies that this extended warranty only applies to N20 engines that were built for the US-market. Therefore BMW Group denies any responsibility in this case. However, I’ve read on this website that in many cases the replacement of the N20 turbo oil feed line was done under the cars warranty. Therefore I was wondering if those replacements were only performed on N20’s for the US-market? Or are there cases known where replacement of N20’s oil feed lines that are built for the (western) European market were (also) carried out under warranty (perhaps a general extended warranty as for the American market)?

    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?

    Like

    • 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?

    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??

    Like

    • 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

        Just to add a quick question on the “covered” vehicles on the N20 oil line extended warranty bulletin. I just had oil line diagnosed as bad on my wife’s 2014 X1 and they said it wasn’t covered although they are paying for 50% of the cost. I think it should be covered 100% not matter what chassis they put that part in especially if the part was designed with a flaw. Am I wrong?

      I just discovered this problem with my 2013 X1, 40k miles, about a year out of warranty. I have a call into the dealer to setup an appt, but my initial reaction is that I am not happy that BMW appears to be excluding the X1 on this known issue, especially since it could amount to thousands of dollars in repairs.
      Jesus – I see you were able to split cost 50% – Any suggestions on how to negotiate with BMW is appreciated.
      I have two BMWs right now, at least the other is under warranty still …

      • No really don’t have any suggestions ,,,,I would recommend the bulletin saying BMW knows there is a problem but the X1 is not covered with the same engine,,,,,also see if they can do some kind of goodwill repair,,,,maybe they will do a 50% split

      • Jesus says:

        I basically pleaded my case to BMW first then the dealer. BMW then communicated with dealer on what if anything can be done to offset my cost. BMW in the end probably asked the dealer to help a BMW customer that has had other BMWs. So in short we got the valve cover gasket replaced and the oil line repaired for $1200 and a loaner for a week. We were out of warranty for 4 months for the oil line and as you know no real warranty for valve cover gasket leak. My experience is once the BMW starts leaking its going to find the next weak point in the system then leak again. This is my wife’s choice I drive a GMC truck otherwise I would have traded it.

        A little late, but wanted to provide a quick update here. I’m 100% satisfied with the way BMW handled this issue with my X1. My recommendation for anyone with this problem is to get your vehicle over to a well-rated BMW service center, let your advisor/manager know about the issue and that you’re familiar with the bulletin, and let them advise and advocate for you from there. If you’re ultimately stuck with cost for repairs, definitely run it by your local independent BMW service shop. Best of luck.

    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).

    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

  10. Javier says:

    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)

  12. Javier Guevara Vico says:

    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!!

    My 3 series 2013 BMW just hit 55K miles and started showing the white smoke at start up. I took it to the dealer and they said it was the turbo line and ran my VIN and said it wasn’t under recall, so it would cost me $2000 to replace. But it there was a recall for this very thing on other 3 series made at the same time, so surely it means that there must be a problem on this too? Who should I call to make this happen?

      • What happens when the car shuts off and sits over night oil drains from the engine from this oil feed line and sits inside the turbo,,,,so when you start it up in the morning there is to much oil in the turbo and you get that smoke in the morning until it burns off,,,,the new oil line has a check valve built in to it so the oil does not drain back in to the turbo.

    Hi

    I have a 2012 F10 520i which has been showing “drivetrain malfunction” error for some time now. I have brought it to the dealership and they attempted to fix the issue about 3 times so far but I am still getting the same error. It happens when I press on the pedal “normally” however, if I press on pedal too hard, it doesnt show. If I turn emgine off and then on again, it goes away. I have recently noticed the white smoke if I switch on after 12 or so hours of being parked.

    Can you please tell me if I can show them this bulletin will they do it for free? I have paid around 8000 Riyals already for the 3 times they tried to fix it (around 2K USD)

    Thanks, FYI, after some more research, it looks like Mitsubishi makes the turbos for BMW and other car manufacturers so your factory ones are probably Mitsubishi.

    We have the smoke at start up especially after sitting a couple of days, but we also experienced smoke at stoplights and rough idling and power loss, the whining noise, and much burned oil. My conclusion is it probably isn’t just the intake oil line but the whole turbo as well. Would you agree?

    The pcv valve is fine and the timing chain looks ok from what I can see and wouldn’t explain all that, just also possibly a whining noise. We are 5 days and 5,00 miles below the extended warranty on the timing and oil pump chains, but I don’t think they will cover replacement since it appears to be the turbo and they haven’t actually gone bad yet (although, I think they and the turbos should be recalls). Would you agree with that too?

    Thanks, I am not sure what would cause it to fail so early. I assume BMW would not cover it in relation to the oil feed line problem. I think California might have heavier emission issues protection but I am in Illinois. I used to be a big BMW fan, but now I am really disappointed with this n20 engine and the multiple potential issues including other engines. If they sell their cars at a premium because they supposedly make premium cars, then their warranty should at least match Hyundai’s 100,000/10 year warranty, especially when they decide to cut corners by using more parts out of plastic like timing chain guides and valve covers.

    Parts at $408.93 includes the following:
    11-42-8-678-840 Oil Pipe Inlet-$68
    11-65-7-625-293 Gasket Ring -$12.98 x 4 =$51.92
    18-40-7-502-196 Flange Nut -$8.98 x 10 = $89.80
    11-427-577-017 Asbestos Gasket-$19.98
    11-53-7-634-204 O-Ring-$6.98 x 4 = $27.98
    83-51-9-964 Anti-Freeze 1 Gal. – $28.40
    18-30-7-606-136 Screw Clamp- $61.98
    18-30-7-581-970 Gasket Ring- $37.98
    13-71-7-599-291 Gasket – $22.98

    I see smoke during cold start. Can’t tell when it is the turbo leaking oil or just condensation. If I have this issue, would the smoke smell like engine oil?

    Hi bmwtechnician, My car X3 2014 i28 has Smoke at cold start up for about 10-20 sec.
    And the warranty cover missed by a week for my Car, so I want to know the cost of changing the oil feed inlet pipe and also, is it ok to leave it as it is for about 8 months and then change the car?
    Does it cause any major issues if left as it is? I have no other issues only smoke at start up.

    Thanks,
    AB

    • The cost is about 5 hrs labor plus the parts,,,,I don’t know the cost of the parts,,,,you can let it go for awhile but not to long could cause some turbo issue later on.

      Hello,
      I went to dealer, showed how my car missed the turbo oil feed line warranty coverage by just 10 days and told when I called BMW warranty helpline theay asked me to check with service Manager at my BMW service center to consider good will discount and so he considered it , got turbo with all feed lines changed for $1900. So always try before paying right out full money, as I was quoted $4600 by same dealer before this happened.

    My 2013 328i xdrive with N26 engine that has the same bluish exhaust smoke on cold startup. The longer it sits, the greater the amount of smoke. Manufacturer date is 3/2013, which is in the range of the technical service bulletin for the turbocharger oil supply line issue (https://static.nhtsa.gov/odi/tsbs/2017/MC-10146570-9999.pdf). However, there are no recalls on my VIN and the car has over 130k miles. Any chance that the dealer will cover (or at least share cost) or am I on my own for the repair? I’m assuming that it is not a blown turbo since the car is running pretty well otherwise.
