BMW’s technical service bulletin SI B 12 33 06 (issued October 2006):

BMW's service procedure for checking the oil level sensor does not require a factory scan tool or any other fancy electronic diagnostics. You simply drain the oil out of the engine, measure it, and then pour the correct amount of oil back into the engine. If the oil level sensor still reads low, replace the sensor and the problem is fixed.

Electronic problems in the CBS oil sensor circuit can also cause other problems. BMW’s technical service bulletin SI B 12 33 06 (issued October 2006) *describes some of the seemingly unrelated problems that can be traced back to faults in the oil sensor *circuit. These include:

• Engine won't crank (E46, E53, E83, E85, M54 & N62 models);

• Charging system is not working (E53, M54 and M62 models);

• "Engine temperature fault" message displayed, but the engine is not running hot or overheating (E60, E63, E64, E66 & N62 models); and

• False oxygen sensor fault codes (E60, E63, E64, E66 and N62 models).
