BMW N54 Rod Knock or AC Compressor?
Hi guys,
Im from germany and yesterday i bought a 335i e93 with Stage 2+ mhd fbo..
car did run good just small things like 30FF code..
Today something very Bad happened! I stopped at a red light and The Engine Shut down.
After 2-3 min and praying to start up, it started (very Bad..) i luckily was near to my mecanic! I drove the car to his Garage, and then i Noticed a KNOCKING NOISE🧐 and a Little Bit of smoke from the left side of the hood (white smoke) i though okay maybe the knock is bc of the injectors… checked it with Carly and it says misfires on cylinders 5,3,2 and smth with ignition misfires too.
Okay Fine im gonna buy those index 12 and have some fun again…. Then my mecanic started the car, After 5 sec he told me: turn it Off, its a rod bearing failiure? Im shocked! I bought it yesterday…
But! In Germany we say „The Hope dies last“
The previous owner told me: The ac doesnt work! He tried to fill it up etc but it didnt work.. and 3-4 weeks ago he changed some pulleys down there.
I saw a video, can the AC Compressor fail sound like a rod knock? After clearing the codes the car runs fine, and the knock is not very loud! I Think it comes from
The front motor.
But i opened the oil lid and it really smells like a lot of unburned fuel…
I Need your help guys! Im so Sad Right now.
