Two problems related to engine rattling and whining sounds have been reported for the 2010 BMW 328. The most recently reported issues are listed below.
Occasional rattle noise at the front end of the running motion engine followed by surge power and error code 2a87 and 2a7a vanos related dtc. Vehicle then become rough idled.
While driving my vehicle from work, I was at a red light when my vehicle started making a rattling noise and cut off. It wasn't in motion at this point and it wouldn't start after cutting off. I had it towed to a mechanic shop to have it checked out. Their report was determined that it was the timing chain, so I had I towed to the nearest BMW dealership (tom bush BMW on atlantic blvd),where they currently have it. Right now, just to open the engine to see the extent of the damage is a $700 labor diagnostic test, which is rather pricey!!!. I saw that there is a recall on some of their other BMW vehicles concerning the timing chain and I would like to know if the 3 series is a part of that recall?? my vehicle is only 5 years old and shouldn't be having problems with the timing chain. Your assistance is greatly appreciated. Thanks!.
