N54B0 problem knocking on idle ( really noisy) not normal

misiumesiu · 04-16-2022, 12:56 PM

Hello guys,
my car is making a strange sound at idle, when I rev up or shift the transmission from d to p it stops. It is a very loud sound, the first time I heard it I thought it was a rod bearing. I am attaching a video of this sound ( firstly kocking and then normal sound).
Please help me guys

Sounds like lifter tick to me

these cars do it sometimes. Does it happen a lot?

Hello,
this is normal, this is the canister purge valve. Sometimes it sounds like that. My 335is make the same noise sometimes.

It's either the Purge valve or Lifter tick.

If it goes away after the oil warms up the it's likely the purge valve.
