Hello guys,


Kindly, I need your expertise and advice.
I had a very long story with my dealer. I don’t want to waste your time so here is the summary .
I have a 2012 F30 335i which is still under extended warranty. I took it to the dealer after I heard a weird squealing noise that sounded like a loose belt just before the car goes into ready mode when auto stop/start function is on. After many visits to the dealer because of misdiagnoses, many parts were changed in a try to solve the problem:
• Rear engine crank seal
• Front engine crank seal
• Valve cover change
• Car was reprogrammed
These are the parts and things that I know about. I don’t know what else might have been done to the car. Squealing noise was solved, and I think it was a bad PCV because the dealer didn’t tell me the real cause of the problem. They claim the noise was caused by all the above mentioned parts.
I got into the car at the dealer and I took off. As I did, I noticed that the ticking noise of the engine was higher than usual, it sounded more like knocking now. After the car got to operating temp I heard a vibration noise whenever I stopped at traffic lights. I paid more attention to morning start ups, and I noticec puff of smoke that lasts for almost 10 seconds.
The dealer’s diagnoses concerning the vibration noise was “bad torque converter”. As for the knocking noise, the Service Manager objected my suggestion of bad fuel injectors or hydraulic lifters.
Following a long process of hustle and bustle, dealer changed the transmission with a new one under extended warranty. Fuel injectors were changed as well.
Now, I still have all the noises. The puff of smoke they claim to be normal. Nothing has changed. Moreover, the Service Manager now blames the knocking noise on the transmission. After BMW Service Manager informed me that the knocking noise is caused by the transmission, and not only the old transmission, but also the NEW ONE, I decided that I’ve had enough. Here is a literal quotation of his explanation in his what’s app message he sent me:
BMW Service Manager
“This is the sound from transmission it will never go away.” Then he says, “sometimes we(BMW get) lucky (when changing the transmission) and it (the noise)reduces but it is there on certain engine and transmission combinations 5 series was mostly effected but it also because we sold mostly 5 series with same combination.”
What he is saying is that BMWs with N55 engines & 8hp-45Z auto transmissions, make this noise!! This combination includes a great deal of cars!!
It IS really heart breaking to know BMW that we love depends on luck when fixing cars under warranty.
I can’t wrap my head around this! Is this noise really normal with these combinations?!! Does BMW new transmission makes some weird knocking noise? Does BMW really make cars as bad as these!
Here is the noise for you to judge. The dealer might prove right, and I might be wrong.
Kindly watch the video in the link below, and let me know your thoughts on youtube and/or here



Thanks in advance,
Albert
