Your right, we don't know the median failure km. What we do know is that these cars aren't that old, and the issues are happening. My dealer said that they did many 2012 F30s and X3s had a higher rate. They said it was the worst of all the years. They said they always had at least one car in on timing chain for quite some time on those models. It couldn't have been very high mileage a few years ago. They said 2013 and up is better but still prevalent. He said it's not a one off case.

I know an employee in parts on a more personal level. Perhaps that's the only reason why.

Has anyone had this done by pros? If so, any issues... ?
My n20 has ~64,000 miles and is now experiencing the whining. I'm likely to spend the $4k to get it done but before I do it I just want to check to see if anyone has had any residual issues after getting it done.
I'm assuming as long as the job is done properly that everything should be smooth going forward but I just want to make sure before dropping (ugh) the cash. |

Make sure that the indie provides some assurance or warranty for their work. My Indy would guarantee and insure their work free of defects. Also note that you can have 75% of it paid by BMW. Make sure that the indie keeps a detailed and meticulous parts sheet of only, and I repeat, only BMW OEM parts. Take a video that includes the whine, the VIN, and the odometer. Technically, you only need the parts sheet and receipt. but do the video as backup. It would be cool to see some internal pics of what's happening to the guide and chain leading to this problem. If you could share that, that would be really awesome. How often did you do oil changes? What year and model?

I am getting a diagnostic at a BMW dealer for the oil pump drive chain (the whining noise). So I can use that when I contact BMW NA about any coverage they can (and SHOULD) offer. The timing chain at the moment is actually pretty taut and has zero slack. But I'm still pretty nervous driving because of the imminent failure caused once the oil pump fails. As far as I understand the timing chain assembly could go very shortly after the oil pump fails, like on the same drive shortly. This is all very new to me - I am learning as I go... One peace of mind that the Master Tech gave me is that I could proceed to change the oil every 2-2.5 thousand miles from now on (for a period of time) which would prevent any future sludge potential and also clean out the engine sludge as well over time. This makes me feel alot better about my future with this car (which I F'n LOVE)...and have several plans for in the future. As far as pics, right now the chain and guide look the same under the cap as any others I've seen. I will take pictures of the drive chain, timing chain, guide, and assembly once the job takes place hopefully it will be within the next week. But, at the moment, there is HOPE ! Thanks for the response as I consider an indie as well |

Just so that you know, you are legally covered and will be paid by BMW at 75%. It has been settled. You would need to pay the other 25%. You just need to follow BMW requirements and they will reimburse, assuming that your year and model is included. The whine is all you need and is the only metric used to determine the issue. There is no need to inspect it under the valve cover first. When doing the procedure, the valve cover and oil pan are removed as part of the process so no need to pay extra. With this procedure, you can pretty much see everything in the engine without paying extras for removing things. If they are charging you for that, then they are ripping you off. Personally, I would definitely not drive it at all until the chain is changed, unless you are okay with possibly having to get a new engine. The whine is there, so if you continue to drive it, your putting the engine at quite a significant risk. I would consider a tow truck for moving it around. Just a heads up.

I also was strongly considering the tow trucks, I haven't driven the car for 2 days but drove it for almost 7 days with the whine. Even if I were to drive it, isn't there some kind of warning that happens when the oil pump fails? giving me time to just pull over and shut it off? I should probably just not risk it. I'm aware the valve cover is not needed to inspect the issue, I was just curious about that because of the long oil change intervals. Well, this is looking pretty promising. I'll be making my phone calls at open of offices tomorrow! |

If the low oil pressure light comes on, it's typically already finished at that point, or some damage has been done. That light means the chain has come apart, and there's fragments that have gone into the oil that will be blocking the intake or just generally be contaminating the oil depending on which chain came apart. If the primary chain comes apart, then the timing will also be off which of course causes many irreversible/expensive problems. There is a lot of info here both on the issue and settlement: Another F30 N20 Blown Motor Thread https://f30.bimmerpost.com/forums/sh....php?t=1614899

I also found alot of details on this link - not sure if it 100% accurate but it's very comprehensive in the breakdown.
https://www.law360.com/articles/1304...ne-defect-suit Here's some excerpts: After the initial complaint in 2017, BMW of North America extended the engine warranty for the chain assembly components from the original four years or 50,000 miles to seven years or 70,000 miles. As part of the settlement, BMW agreed to continue to honor that extension and will also reimburse people for unreimbursed past chain assemblies repair or costs that took place before eight years or 100,000 miles. Replacing both chain assemblies (primary timing chain, tensioner and rails/guides together with the oil pump/counterbalance shaft chain and sprockets) costs about $4,500-$5,000 if there is no engine damage, the agreement said. And plaintiffs have gotten estimates upward of $12,000 for engine replacement, the filing said. The settlement will reimburse customers who had out-of-pocket expenses to repair or replace one failed timing chain module and/or one failed oil pump drive chain module. If the parts failure happened before the seven years or 70,000 miles threshold, the customer will be reimbursed 100% of the cost, including any associated engine damage, for work done at an authorized BMW Center. For work done at an independent service center, BMW will reimburse up to $3,000 for the timing chain module or oil pump drive chain module and up to $7,500 for engine failure, according to the settlement. Failures between years seven and eight and up to 100,000 miles, whichever comes first, will be reimbursed for work done at an authorized BMW Center "in accordance with a contribution schedule" that decreases the reimbursement amount as the mileage increases, the settlement said. The same sloping reimbursement schedule applies for work done at an independent service center, but it's capped at $3,000 for the timing chain module, oil pump drive chain module repairs and $7,500 for the engine failure repairs, according to the agreement. Engine chain parts that fail in the future will have to be repaired at authorized BMW Centers only, giving those class vehicles up to eight years or 100,000 miles and is also subject to a schedule that reimburses less as the mileage on the vehicle climbs, according to the deal. Also, for one year from the settlement's effective date, any class vehicle with less than 100,000 miles, regardless of its age, that experiences timing chain module failure, oil pump drive chain module failure, or engine damage or failure due to timing chain module or oil pump drive chain module failure, may go to an authorized BMW Center for repair, subject to a decreasing reimbursement rate as the mileage on the vehicle increases, the agreement states.
