N20 Timing Chain failure Drivetrain malfunction. BMW F25 X3 2013 53,000 miles

My wife's 2013 X3 just stopped and gave a drivetrain malfunction error in the middle of the road while she was driving.

I was unable to move it and could not push it.

I tried the emergency electronic release but after 20 minutes realized no matter what I did it would not work.

Then I remembered the manual release screw under the car!

This video helped.... But I had to remove the panels underneath with a 8mm socket to gain access to the Allen wrench screw.

Let me say..... what a pain in the ass!

Finally got the car out of gear and towed home. To make matters worse warranty just expired 3 months ago, car now has 53,000. I swear BMW does this on purpose.

No I am trying to diagnose the problem..

I am hoping its something simple... I have seen where the ignition coils have failed locking out the transmission to prevent damage...

ANy help would be appreciated. I cant believe how dangerous this car is designed. I was stuck in one spot for 1 hour trying to disengage the gear lock. I hope this helps someone else. The car was unable to be moved or towed until the lock is disabled.

Anyone have any idea on what it could be?...

***UPDATE***
The timing chain and or timing chain guards failed resulting in a total loss of the engine.


I have had many people with the BMW N20 issue email me of similar failures and am keeping a list here...

BMW X3 timing chain problem

My 2013 BMW X3 at 40,000 miles had a timing chain break blowing up the engine. It just came out of warranty 2 months ago. Is there a support group?
