wow that's so good to hear! i m glad they took complete care of it.This is his update, post #51:
"BMW stepped up and is completely covering the repair. They are replacing the engine at no cost.
I had to get BMW NA involved, but actually they went above and beyond and I am very happy.
Was nice to see them take care of a loyal customer."
Actually couple of years back i did get this "Drivetrain malfunction" message but my car did stop completely but it was wobbling as if it got skid and after i come off the road and wait for few minutes it came back to normal , this happened like 3 times. so i took it to the dealer here and not sure what they did but from then on i never had that again.This does not happen to all BMW vehicles with the N20 engine, but it is a known risk. Owners that have experienced such a failure are much more likely to post than those that don't. Some N20 engines have been reportedly driven up to 100K miles without this failure. Some owners have proactively had the timing chain guide changed to the improved design introduced in January 2015, but this is not inexpensive and is not something BMW has routinely covered to date.
I suggest you check with the third party providing the warranty to confirm whether such a failure will be covered under the warranty. Get the answer in writing if possible.
how can i recognize that there is a timing chain problem, i mean is there a specific sound that i should listen for ?The probability of timing chain failure in the N20 engine is difficult to quantify from publicly available data. It is a risk, but not inevitable. There is no reason to believe that the majority of N20 engines from any model year will experience this problem.
What may you do to minimize or address this potential problem? Listen regularly for a change in sound from the engine that may signal timing chain problems and take your vehicle promptly into your service provider if you hear this. Consider having the timing chain guide replaced with the new part, but be aware this is expensive and BMW will not typically cover this expense. You may purchase a warranty to cover the repair costs in event of timing chain failure. Some suggest a shortened oil change interval may help to avoid problems. You may participate in a class action lawsuit in an effort to motivate BMW to provide repairs or an extended warranty.
If you are not comfortable with the risk and steps that may be taken to manage the risk, then it may be time to trade your X3.
i believe its 6 cylinder, during the time of purchase i remember the sales person saying its inline 6 cylinder also when i look for my car value in edmunds its shows as 6 cylinder.Jay, on more than one occasion you mentioned you're worried about this problem. Is your car a 4 cylinder engine or 6 cylinder 28i?
the 4 cylinder is what's being discussed on this thread.
The 6 cylinder does not have this issue.
i have 2012 X3 should i not worry about this ? ThanksYou must have bought your 2013 as a CPO or with an extended warranty. They only had 50 k back then too.
The x3 timing chain concerns was 2013, 2014 and early 2015 or so says BMW. I have 47 k on my 2014 right now and thinking of trading out of BMW altogether
