7/70,000K timing chain warranty.

Just to let everyone know BMW has added a 7 year 70,000 mile warranty on the timing chains that continue to become stretched and break. Not much of a relief to n20 owners since most break after 70K but if they fail before then, warranty should cover it.

I forgot the model years, but I know the older models were definitely covered. 2012-2014

I have been reading with interest this issue on the timing chains with the N20 engine. When BMW released the latest version of the 2.0 4 cylinder B48 (2017, 2018), I'm assuming that the timing chain set up was re-designed, because of what was happening with the N20. Is that right?

I believe the N20's (N26) produced after a certain month in early 2015 already had the re-designed timing chain set up. Although I'm not exactly sure what month.

Does anyone know the percentage of N20's affected? Is this a widespread issue or is it relatively rare?

I have zero idea... but can infer from the increased warranty on an entire batch of cars, that this is not a "rare" problem. If it was, they would just handle it "one off" style.

I DO NOT know if this is true, but read elsewhere that a class action lawsuit has recently been initiated against BMW for this N20 timing chain issue. I have read in horror, where some of these timing chain issues created a total engine loss and the cost to replace the engine was anywhere between $14K and $28K. For some of the older model year cars that cost was more than the value of the entire car and the car was simply scrapped. Yikes! I really hope the replacement B48 engine that is now in BMW's does not develop problems.

BMW engineers are so confident about B48/B58 that, now the timing chain is at the back of the engine, so any issue with timing chain needs to remove the engine first.

Do we have any way of confirming:
1. That BMW extended warranty to cover timing chain problems on certain model years
2. That a class action lawsuit was filed. Where filed and by who.

Agreed. First TSB, but if it's more widespread, they extend the warranty or recall the car.

And BMWNA did extended the warranty to 7-yr/70k-mile.

I did some brief internet research and found a class action lawsuit that may appear to have been a reason for the recently extended warranty for the N20 engine. But I DO NOT know if there is a different class action lawsuit.

Totally agree with you . The good news is that it appears that BMW has created a modular engine family that the B48 is a part of. The B38 is the 3 cylinder version (for the Mini), the B48 is the 4 cylinder version and the B58 is the 6 cylinder version. In doing some research ALL of these BMW engines SHARE many internal engine components in an effort to save production costs. So knowing that these engines would be so widespread throughout the company, hopefully BMW took great care in the engine/parts design to avoid things like this N20 timing chain issue from happening again (fingers crossed!).

There was a similar issue with N47(diesel), and that engine's timing chain is at the back:

You are definitely correct, I saw that too when I did the brief research on the N20 timing chain issue. My only hope with the B48 is that since so many internal engine parts are now shared in this fairly new modular engine family, that BMW did a better job of designing the parts. When I researched this, I discovered that 60% of ALL the engine parts are now shared among ALL BMW gasoline engines. Even 40% of the internal engine parts are shared with the BMW diesel engines. That means that these engine parts are in many more vehicles, which opens BMW up to a much bigger issue if a problem develops with a particular part. So I just hope that forced BMW to put more emphasis on the design of the parts. Of course there is no guarantee that some type of problem might develop, it's just a hope at this point (fingers crossed!)

60% and 40% are very interesting, it does suggest BMW can focus R&D efforts into common denominators and can potentially improve engine reliability.

At the same time that also means all(?) B engines with modular design will have timing chains at the back, and accessibility and serviceability are not high on BMW engineer's wishlist.

Just got my letter today. It's useless for me since I have an extended warranty to 100K anyway. Plus, I'm already at 72K miles.

I'm hoping I won't have to keep the car beyond 100K, but if I do, I hope the timing chain doesn't give just as I go past 100K!

Mine is past 50k, the shiny patches are growing, but there seems to be no high pitch whine yet.

BTW, the local foreman diagnosed the high pitch whine on another F30 at the service bay while my car was dropped off for oil change.

That whine was quite loud, so it will not be missed easily for those who pay attention. And local indy says it will be a $2k job if caught early enough.
