M272 Engine Timing Chain Sprockets:

Early M272 engines experienced wear in the timing chain balance shaft sprockets, leading to rough idling and check engine lights. While Mercedes-Benz addressed this issue, it's a potential concern.

Evaporator Leaks:

Leaks in the A/C evaporator core can lead to loss of refrigerant and poor A/C performance.

ABS Esp Module:

Some W211 models, particularly earlier ones, had issues with the ABS/ESP control modules. The 2008 facelift may have seen improvements, but it remains a point of attention for diagnostics.

Air Suspension Component Wear:

If equipped with AIRMATIC air suspension, components like air springs and compressor can wear over time.
