What it covers

A service bulletin tells BMW technicians how to diagnose or fix a known issue. It is not a recall: a repair under a bulletin is normally paid by the owner unless the car is still under warranty or a warranty extension applies.

SUBJECT ALPINA N63TU Overboost Faults Set at High Altitude. The ""Drivetrain Malfunction"" Check Control Message is displayed when driving under certain engine operating conditions and at high altitude (above 6500 ft/2000 m). The engine has reduced power until the ignition is cycled off and back on.
