Report the problem and request a timing chain tension check test upon acceptance.

A BMW inspector will come to check for possible stretching of the upper chain of the BMW N47 engine and, if it is out of tolerance, it will be replaced.

If any other wear issues are added to any stretching (guides, chain tensioners, etc.), the entire chain assembly (top and bottom) will be replaced.

THIS IS NOT A RECALL. BMW did not carry out a global recall, but only a vehicle-by-vehicle sample check. It is therefore your responsibility to check the car and subject it to the tests listed above.
