Hi All,
I've got an e90 320d with the M47 engine.
I have replaced the following:
Serpentine belt - gates
Power steering belt - gates
Idler pulley - ina
Tensioner pulley - ina
Alternator pulley (solid not clutch) - bmw
The tensioner pulley was torqued to 25nm and 90degrees.
The tensioner has quite abit of play/ vibration in it when running.
Would taking the serpentine belt off and installing it in the opposite direction fix this? Or would it be something more sinister causing this?
