Evidently it is as owners have experienced the same e60 issues on the f10.
Disappointing that a big marque such high as bmw did this and not rectify on a new model launch.
One of the reasons I have keep my extended warranty and main dealer service for when this problem arises I have a leg to stand on.
I will most definitely ask the dealer to log my visit and mark in the the future to carry out further check.
I have just had the major oil service and the health check reported everything well. Don't know how thorough these are but will use this as well as leverage to the case should it arise.

The issue with these modern engines is that the timing chain is now at the rear of the engine due to pedestrian impact safety reasons so doing any check can only involve listening to the engine and that is very subjective unless the timing chain and tensioners have already failed. Due to its position there are no manual checks that can be carried out as far as I'm aware without removing the engine from the car.
