M156 Specific Concerns:

While the M156 is a robust engine, early versions could experience camshaft wear issues (often addressed under warranty or recall). Oil consumption can be higher than standard engines. Regular oil changes with correct specification oil are critical.

Airmatic Issues:

AIRMATIC system can develop leaks in air springs or compressor failures over time. Control modules can also be a failure point. Diagnostics are crucial.
