    I have a 2012 X1, I had heard the timing chain whine get worse over the winter, so I parked the vehicle the end of May, and slowly ordered the parts and the timing chain lock out kit for my mechanic. It was a good thing I did, I was talking to him the other day and he said the the top right timing chain guide had failed and was just kind of floating around. I was lucky I didn’t lose the engine. He said there were bits of plastic in the bottom of the oil pan. It was thanks to this blog that I was able to save my X1, hopefully I won’t have anymore issues with this!

    I have a 2013 328i with 85k miles, mostly highway if that makes any difference. At 77k miles, I got a low oil pressure warning light, towed 100 miles to the dealership and they couldn’t find anything wrong. Eventually replaced some kind of oil flow/distribution sensor of some kind as a starting point.

    Serviced at 80k as usual, with nothing appearing. Also took it in at 84k for a $150 diag fee because I could hear a whine, but since I was reading all of these threads, I wasn’t sure if it was just me worrying. Sure enough, 85k lead to another Low Oil Pressure warning light. Towed to BMW dealership, and 4.5 hours of labor to find out that the Timing Chain guide was broken.

    Dealer originally quoted $4700 for repair, which included some BMWNA assistance apparently. I called BMWNA directly to escalate and hit a brick wall for 10+ minutes, no help whatsoever. Apparently, extended warranty is their ‘sorry’ and any other issues after this is just wear and tear. Eventually the dealer lowered to $3700 because of my loyalty in giving them too much money, (Taken the car there since I got it 2 years ago at 45k miles)

    The question I have, is what questions to ask? I have researched as much as I can, but want to know what else to ask to be replaced whilst they are in there. Oil Pump? Oil Pump Chain? Anything else?

    The notion that these problems are isolated isn’t true – the SA spoke about the frequency of these (mainly X3’s).

    I understand the risks of owning a BMW compared to a generic car, but to think that another four-figure repair bill could pop up is nerve wracking to say the least. Unfortunately, I put way too many miles into the car which had lead to me being upside down in it anyway compared to my loan. Stuck.


    • No I really can’t think of anything else they should replace,,,,they should replace the timing chain and guide rails and oil pump chain and guide,,,,,it’s up to you if you want the oil pump replace at the same time,,,,they will be inside the oil pan when they do the other work, it would only be a couple more bolts to replace at that point

    Hello – I stumbled upon this page and am so appreciative. I started getting this whine and saw your post and the SIB you posted. Took the car to BMW as I am almost at 7yrs and at 65k miles, and they said I will get the SIB 11 03 17 as outlined above. Car has been in the shop for a day, and tech said they’ll let me know if they see anything else, while they have the engine open. I understand they will replace the timing chain and guide rails and oil pump chain and guide. But I want to be smart when they call me and try to hit me up with other non-warranty issues. What else could they possibly find that may not be covered due to this issue? I suppose they could suggest I change the oil pump? What would be a reasonable cost while they are in there, and is there any reason to change it? I suppose I want to be smart and not let the dealer fleece me while they are at it. Any advice is appreciated and thank you for your good work.
