    My BMW service center is refusing to acknowledge that this is an issue. My car has all of the symptoms of the timing chain failure…high pitched whine, power loss, excessive ticking from the engine. Could you suggest the best way to get them to do the work?

    Hi, I found your blog while doing research for modifying my i3 BEV. I have so many questions to ask you! I’m happy to donate to cover your time.
    I’m planning on retrofitting Comfort Access drivers door handle, replacing side-mirrors with cameras, swapping standard seats for lighter more-supportive bucket-seats. These projects have stalled because I can’t find the vital info anywhere on the ISTA system, RealOEM or other forums.
    Do you have an email contact? You can contact me via my site at xaveus.com/contact

    • Sorry I don’t send out my email,,,,all questions can be asked on this blog,,,,it sound like you plan on modifying your I3,,,the modification you are planing removing side mirror with side cameras and retrofitting comfort access are not something BMW has in their software,,,BMW doesn’t want people to modify their software for any reason,,,I’m sorry I don’t have any info on this.

    Hi. My 2012 X1 xdrive20i does have a rev whine to it that sounds similar but becomes softer when the engine heats up. There is no clicking or power loss as some others have indicated with theirs. I noticed that on the list it shows 06/2012 as the production start date. Mine was produced in 10/2011

    Would mine also be affected by this?

    Thanks for the quick reply. I had it in for a service yesterday (145k km) and the SA told me that he dont want to put it on the job card as he would then need to quote for it but there is no error codes on the car that would indicate a failure but the whine it makes is the oil pump and I would need to have it replaced. It is subtle and can be heard inside the vehicle while driving. I am just concerned that they are trying to pull a fast one on me considering I am out of MP. The previous owner did report a “engine whine” (98k km) while it was still in MP but nothing was done about it then.
    I am in South Africa so how would I be able to find out if South Africa acknowledges this problem or not?

        So some good news. I was able to talk to BMW South Africa. They confirmed that the Timing chain Fix has already been done on the vehicle while it was under motorplan. It was replaced under a “Engine Whine” jobcard just before it went out of motorplan. So I took the car to the dealer that actually performed the job as it was close to my work office. The Workshop manager took a listle and said that even though they sound very similar he thinks it sounds like a tentioner or a bearing. Booking the car in on Monday to have him do a full diagnostic on it but he is almost certain its not the oil pump or timing chain.

        Thanks for your blog

        My 2013 X3 N20 timing chain with guides was covered in February 2019 in Canada. I was lucky I had the X3 in for misfire (just a programming issue) and I stated that the engine whine was increasing. The SA noted my complaint and they had the timing chain and guide replaced at 107,000 kms. In Canada, we have the 7 year/112,000 km coverage. I was very lucky my X3 somewhat randomly started to misfire just after the coverage came out but before we hit 112,000 km. That’s the good news… now I have the oil burn and white smoke on cold starts. Turbo supply line or possibly turbo issue.

    First off, thanks for posting so much about this issue (and many others I’m sure) on your blog. Really helps to have an expert like yourself relaying accurate info. I should mention I’m not a car guy so please forgive my dreadful lack of common BMW knowledge your other poster’s have.

    I drive a 2012 328i F30 Series (Prod. date 4/21/2012 / 59K miles). Yesterday I was doing my normal Saturday errand running and got the infamous “Drivetrain malfunction” error followed 30 seconds later by the “Engine oil pressure too low” error. I pulled immediately onto a neighborhood street and my engine died soon after. I called a tow truck guy who couldn’t even get my engine to start to put it in Neutral to get it on the flatbed. After towing to BMW the service guys acted spooked by my engine, saying it had no compression and there was no coolant. They checked my history and saw I hadn’t brought it in for service in something like 19k miles (which I haven’t bc it’s out of warranty and I’ve been getting it serviced by cheaper alternatives like Pep Boys). But tbh, the car has been running fine and I haven’t gotten any lights for oil (have run oil level diagnostic several times in past couple of months), break fluid, etc. If I did I’d bring it in immediately. Anyways, I left the car over the weekend for them to diagnose the issue (which is going to be $585 mind you!!!) and they are going to call me back on Tuesday of next week.

    From what I’ve read on this blog and others, all signs point to the timing chain issue and according to the chart you posted above, my vehicle would be covered. My question is – if the service guys try and tell me the issue was caused by something other than the timing chain and my engine will be super expensive to fix or needs to be replaced, what can I do or say to make sure it wasn’t the timing chain issue? In other words, can I say to them “did you check the xyz?” I just want to make sure I don’t get taken for a ride!

    Like

    • First I don’t know how the service guy can say the engine has no compression from just looking at the car,,,to check compression you need to remove the spark plugs and attach a compression gauge,,,ok that being said the engine oil pressure light could be the oil pressure sensor going bad or it could be the timing chain causing the issue,,,,now if the issue is the timing chain you will have to tell them about the extended warranty on the timing chain,,,,also if you have any records from Pep boys service you can show them will help you showing it did take care of the car.,,,also have them show you the diagnostic report on what is wrong with you engine and have them show you if they can,,,I hope this helps

        Thanks for your response! If they show me the diagnostic report for my engine it might as well be in a different language but maybe I can try and get a copy of it and post it on this blog for a professional to take a look at. In your experience, do the symptoms I just described sound like a timing chain issue? I don’t recall hearing an engine whining or anything like that. Also, if the engine is under warranty for 70k miles and I am only at 59k, wouldn’t they cover whatever is wrong with the engine anyways, even if it’s not the timing chain?

        Like

      • What kind of warranty do you have that goes to 70k?,,,it could be a timing chain or the oil pressure switch could be a problem,,,,if you do have a warranty to 70k yes they should fix it.

      • Chris says:

        The warranty I was referring to would be the 7 years/70k Miles covered by the timing chain issue. The production date of my car falls on a date that according to the chart you posted at the top of this blog post, says my car would be covered. Just hoping that was in fact the issue with my engine (the timing chain) so that BMW covers it under the warranty. And wanted to make sure I knew what I was talking about if they say it’s not the timing chain and something else.

    Help!!! My BMW Service Advisor just called and set my engine was blown and will be $17k to replace. He said the technician found bits of metal in the oil tank (probably from the turbo) and my engine oil level was low. Which is interesting because my car never once gave me a warning that my engine oil level was low, even when I ran the oil level diagnostic on iDrive less than a month ago.

    So of course I brought up the faulty timing chain and oil pump 7yrs/70k on my N20 engine (my car only has 59k miles so is covered). The Service Advisor looked to see if I fall under that warranty with me on the phone and then confirmed that I do in fact fall under the warranty. He then told me that the technician’s diagnosis did not involve the timing chain or the oil pump so that he doesn’t think my engine is covered anyways but would check with the technician.

    If he calls me back and says that the technician tells him that wasn’t the issue and my engine isn’t covered what do I do??? How do I prove that it was the timing chain or oil pump that was at fault? From every post I’ve read and video I’ve seen about this issue, all signs point to the timing chain being the issue!

    Like

    • There is no why for you to prove it was the timing chain,,,,BMW is going to listen to the technician,,,,what probably happen is the technician removed the oil filter and found metal inside the filter, now we have to find out where that metal came from, you need to ask them where the metal came from and what did they find,if they are vague about what they found,ask them did they remove the valve cover and did they inspect the timing chain, tell them maybe the timing chain did all this damage and it should be inspected,,,,,I hope this helps,,,,good luck

    Good morning bmwtechnician, I have a 08/13 build date x1 n20. From what I’m see on the timing chain problem, most of the timing chain guides posted, they were darker in color than what I have in my engine. The guides in my car are of a light coffee color, not the dark brown guides. Would the timing chain guide color be any indicator if I have the updated guides in my engine? I have 52,000 mikes and the engine does not whine or make any noise other than the injectors.

    Hi BMW technician,

    First of all thanks for putting up the list to show clearly about the timing chain issue. I got my BMW 328i 2015/03 build and its definitely out of the provided list of 7 yrs/70000 miles warranty. On the other hand, the BMW replacement website shows my VIN is eligible for two programs. N20 Leak Diagnosis Module and EPS Motor Bolts. Are these issues serious?

    I got the car as pre-owned and I plan to keep the car at-least for 5-7 years until its 150,000 miles. Do you think its worth taking the risk to keep the car that long? Do you suggest any warranty extension program?

    Hello. I was wondering what your opinion was on the following:

    Do you believe that running a flash tune on the N20 motor would increase the likelihood of chain/guide failure? In other words… would running a flash tune increase the stress on these components over the stock tune?

    I have a 2013 X3 2.8i (F25/N20). Last year the dealer replaced the timing chain at 45K miles. A few days ago i was preparing for a cross country trip and noticed the oil level was about a quart low…very strange because it had never burned any oil. i filled the oil to the proper level with the recommended oil. i drove approximately 300 miles and began hearing a valve tap noise that went away once i let off the gas. This turned into a major noise once i exited the interstate and the car then died of major engine failure. The car has been dealer serviced since day one and has/had only 51K miles. The dealer in Virginia said the timing chain was intact and did not feel the failure of the connecting rods is related to the timing chain. They said BMW N/A would pay 60% of a new engine which would cost me $5000.00. Any advice on how to proceed? I found there is a class action lawsuit in New Jersey concerning this issue. Thanks for the help!

    • Wow that sucks after you had the timing chain replaced and 9k miles later,,,I’m amazed BMW is willing to pay 60% of a new engine,,,it’s a hard call do you want to keep the car,,,,also does the new engine include a new turbo,,,,because if metal went through the engine then it also went through the turbo which could cause problems later on.
