| Description of the problem | The vanos system in the 2001-2006 bmw m3 is a common part that is prone to failure. The intake and exhaust bolts of the cam gear can sheer off due to improper torquing from the factory and improper hardness of the bolts. The drive shaft of the vanos system is also weak. If the vanos system fails, the cam gear can sheer off, and parts can get into the engine and cause a catastrophic failure. Sometimes, parts can break off into the hood of the car. This system fails without rhyme or reason, seemingly at random. Many owners have had problems with the vanos system. Please observe the following links: http://www. M3forum. Net/m3forum/showthread.

Sometimes replacing the bolts on the intake and exhaust camshaft with hardened bolts will sometimes fix the issue, but other times, the problem seems random. |
