I have a 2006 M3 comp. ed. and at 79,000 miles the VANOS basically fell apart causing catastrophic engine failure due to defective screws that are used to attach the cam shaft drive cog to the VANOS. This jammed valves on cylinder #2 into the piston and lifted the head off the engine. Luckily I purchased the extended warranty and the dealership dropped a remanufactured engine into my car!!
BUT NOW with only 3000 miles on this “new” engine I have an awful sound the appears to be a connecting rod bearing failure. The MF service manager asked if I had been over revving the engine. F*@k NO. I have always babied my rid, even with the old engine.
I am ready to sue BMW for all the problems and head aches they have caused me; especially now on my second engine failing so quickly.
