Hi e46fanatics,
I have a E46 sedan 320i m52tüb20 1998. I have this slight but noticeable whining noise from the back. When on the throttle you can barely hear it at all, but as you come off the gas (engine braking) the whine becomes louder. I have also noticed it is louder around 40-60km/h (25-40mph) and/or when in 5th gear. It could also just sound louder because the engine is at lower RPM in 5th(and less overall noise at that speed), but I swear it's louder.
Oil in gearbox and diff were changed and didn't do anything.
What could be the cause of this?
Regards,
Anders P.
