Hi Everyone

The last two months I have a metallic ping-in sound coming from the rear of the M3 (cowbell) only when moving the car from 1st or stopping and same when I go reverse but when start moving the car sound normal.
1-No rocks stuck in the brake dust shield
2-No bent brake dust shield,
3-I replace the drive shaft U joint

Do you have any idea what can it be ?

Probably want to move this into the Mechanical or General forum sections.
