2011 BMW Z4 sDrive Recalls
The bolts that secure the housing for the variable camshaft timing adjustment unit can loosen over time and possibly break, causing engine damage and engine stalling. Dealers will replace the four bolts for both intake and exhaust timing units free of charge to resolve the concern.
The vehicle battery is connected to the fuse box via a heavy duty cable. It has been determined that the cable connection at the fuse box can degrade over time, resulting in increased electrical resistance. This increased resistance can cause the connection point to overheat and break, resulting in a loss of electrical power and causing the engine to stall, increasing the risk of a crash. Dealers will replace the positive battery cable connector and secure it with an improved method to correct this concern.
