BMW 2013 750li drivetrain malfunction re-occurring causing rough start and while driving highway 485 vanos solenoids & valve covers have been replaced three times within 7 months on my vehicle that has 22,000 miles. My full service warranty is going to expire at the end of 2016. According to recent reports BMW is aware of this issue on the n63 engine and should have a recall on various parts. The bolts that secure the housing for the variable camshaft timing adjustment (vanos) unit can loosen over time and may possibly break. The engine may have reduced power or stall. An engine stall increases the risk of a crash. Having the service bulletin number b001314, the recall may take several days for each vehicle involved and could include replacement of the fuel injectors, mass airflow sensors, battery, crankcase vent lines, fuel pressure sensor, the engine¿s vacuum pump and last, but certainly not least, replacement of the timing chain. . BMW in some cases will offer an extended full service warranty.
