Three problems related to loud engine noise have been reported for the 2012 BMW 328. The most recently reported issues are listed below.
I was driving down the road at 60mph the computer flashed low oil pressure, then drive train malfunction. The engine started making a loud noise and most complete power to car. Car had to be towed.
I was about a quarter mile from my home when my 2012 328 n20 began to make a loud sound coming from engine. The car also started to idle very rough. Check engine lights went off. I had the car towed to my BMW mechanic and they diagnosed an issue with the timing chain. They verified a noise and a very loose timing chain. Timing chain and guide repair was performed at a high cost. Mileage is 127500.
I just recently had to take my 2012 BMW 328i convertible in because of the engine was making a loud noise plus loss of hp. The technician informed me that the vanos solenoid bolts had broken off into the engine after doing more research into this I find that there was a recall on the vanos gear bolts. My question is do I pay for this repair?.
