Two problems related to engine belts and pulleys have been reported for the 2006 BMW 3 Series. The most recently reported issues are listed below.
Independent repair shop noted aluminum head bolts broken which could cause extensive damage to engine. Broken bolts caused oil leak and heads of bolts could have gone into the timing belt destroying the engine. Independent repair shop directed us to the dealership stating they had noted this issues on almost all of this year and model. Repair cost was very expensive.
Passenger air bags and seat belt wont work and BMW wont fix. Electrical:radio,climate control,headlights and windshield washer pump. Window regulators. And the worst:learning from x_employees of BMW say that BMW purposefully miss-torques oil pan,valve cover and oil filter housing so the fail right after 50,000 mile warranty. Every e90 has these problems. And window regulators all except driver side. In motion.
