M271 1.8 Kompressor
Supercharged pre-facelift petrol. Simple and quiet, and carrying one catastrophic fault. The balance-shaft gear wears and fixing it means the engine comes out.

Engine and component issues
Check-engine light with camshaft/crankshaft correlation codes, rough running, and eventually a car that won't start. The balance-shaft gear was manufactured too soft on a range of early engines and wears against the crank gear until timing is lost. Mercedes revised the part.
Check: Scan for correlation codes before anything else. A clear scan today doesn't clear the car, but codes present are decisive. Ask for a balance-shaft repair receipt with the revised part number; engine number ranges are published and a specialist can check yours.
Later parts: Revised gear; not present on the M271 EVO from the 2011 facelift
