BMW Z4 sDrive RecallsReduced Braking Efficiency
These vehicles use a vacuum pump to supply power assist to the braking system. Due to insufficient lubrication this vacuum pump may fail. Failure of the brake vacuum pump would result in a reduction in braking power that could increase the risk of a crash. In order to correct this concern, dealers will install a locking ring in the camshaft to retain the camshaft seal disk in the proper location. This will ensure proper oiling of the vacuum pump. Note: This recall is an expansion of an earlier recall.
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.
