I have 2011 E92 335xi. The car has almost 80k on it with full bolt ons, jb4, and mhd backend. Car makes great power, and runs fine for the most part. Recently I've run into a little issue i just can't put my finger on. I was told this is the ac compressor engaging but i can't say i agree?

So the only thing i noticed with the car acting different is when turning the wheel completely, instead of the rpms just going up. Most of the time it will have a up and down effect and cause the car to jerk forward along matching the rpms. other then that i have a slick clicking sound every so often when at idle or a quick throttle blimp to 1k will cause the same ticking sound which i'm guessing is the throttle body opening and closing. Heres a video of the clicking noise, notice its pretty loud. from messing with the throttle too much it'll cause the car to die as you can see at the end of this video. (Oil temp was cool also)

Please let me know what you think, car runs fine for now but ill take all the opinions i can get.

I found your post so weird because i noticed the EXACT same noise recently. For me is only when i drive the car hard and then i am idling. I feel like its coming from the area where the boost solenoid is. So i replaced it. Still hear the noise once in a while not all the time. Noise goes away when i press the gas slightly. Returns only on idle. IDK i gave up since car drives fine and no codes. The noise goes in and out during idle..

Same here...not sure what it is but appears to be a normal sound these cars make. Mine only appears when oil is really warm (~240) on a hot day at lowest idle.

Exactly with mine. OP has other issues i dont notice. Dont think they are related.

The other noise i was told is the throttle body opening and closing but my mechanic wasn't sure why it does it so often, it'll make that noise at idle every 50-60 seconds or so.

The first video i posted, that noise is only present when oil temp is high, it doesn't matter if its warm or cold outside but then again my oil temps are usually a little higher then normal considering i'm fbo and tuned to make 500hp on e85.

Im in the same boat, i thought about solenoids also but i have no codes and from the research i decided it probably wasn't the solenoids.

It could be injector noise.. just a wild guess. Mine seems to come from the rear on the passanger side. If ur looking at the engine with hood open.

Do you have stock injenctors? I don’t think it’s injectors or you’d think it’d be constant, it comes and goes only when engine is hot. You can hear how loud my injectors are before the other noise starts.

Yeah makes sense probably not injector. Mine are stock yes.

Lately with the cold weather i dont hear it.
