I went ahead and bought a 320i... the rattle persisted even thru the summer. Yes, mybad for dismissing it and now it annoys the f*%# out of me. A couple of people have asked me if it's a diesel engine.

I've been doing some reading and it seems to be one (or more ?) of 3 issues... they all claim that theirs was the real cause of the rattle.

1. A noisy injection pump solenoid on the fuel rail (worn or missing dampener on the rail?).
2. A worn linkage on the turbo wastegate actuator motor (replace the whole motor + linkage assembly).
3. A worn flapper disc (wastegate ?) inside the exhaust manifold (replace the manifold).

Anyone care to comment ? What was your fix ?


Thanks in advance.

Thats just how this engine runs. Bought my 320i new in 2017 and it sounded like a diesel sort of since day 1.
