    Thank you for posting this. I know the production date of my F26, but how can I obtain the month my engine was produced?

    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?


    • I would try and contact BMW of South Africa and tell them what your problem,,,,they might be able to help you,,,also it’s good that the previous owner also complained about the noise putting it on records.

        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


      • Glad I could help

    Why only 7/70 coverage? If you don’t have an issue by 7/70 BMW figured your in the clear? Sounds like what Porsche did with owners of their cars, 911, Boxster, Cayman, who were having Intermediate Shaft Bearing failures on Pre 09 cars, low mileage car stay away high mileage your good to go.
