Known Issues 3
Single-row timing chain stretch — catastrophic
▸Rattle on cold start, check engine light, timing off in severe cases, sudden failure
Single-row chain stretches and jumps. Engine can be destroyed if ignored. BMW N20-level problem but without the class-action settlement.
AVOID for Greek buyers. Any W204 C180/C200 with M271 needs chain check immediately. Verify replacement before purchase.
Supercharger clutch / belt failure
▸Loss of power, whining noise, check engine light
Kompressor models have supercharger clutch that fails. Labour-intensive repair.
Additional reason to avoid M271. Multiple expensive failure points stack up.
Valve cover gasket oil leak
▸Oil burning smell, visible oil on engine top
Standard gasket wear. Less concerning than the chain issue but adds to repair list.
Expected on age. Fix together with chain service if doing that repair.
