Mercedes CLS Timing Chain Malaysia — M276/M264/M256
C218 M276 V6: timing chain stretch less common than 4-cyl M271 but valve cover leaks often occur first. C257 M256 inline-6: robust chain, oil quality critical. M264: same 4-cyl chain concerns as GLC. Malaysia chain replacement RM 3,000–6,000.
CLS Timing Chain — By Engine
- C218 M276 V6: chain stretch less common than 4-cyl — but valve cover gasket leaks come first
- C257 M256 inline-6: robust chain — oil quality and change intervals are the key protection
- C257 M264: same 4-cyl chain concerns as GLC/C-Class — cold-start rattle warning
- Malaysia replacement: RM 3,000–6,000 depending on engine
Timing Chain — Mercedes Malaysia Warning
The M271 1.8T (W204 C200/C250) has a known timing chain stretch problem — this is the single most critical maintenance concern for used W204 owners in Malaysia. Symptoms: cold-start rattle that disappears after 30 seconds (chain stretch), P0016/P0017 fault codes. Fix: full timing chain kit replacement (RM 2,500–4,500). Later engines (M270, M274, M177) have improved timing chains — but still require proper MB 229.51 oil and 10,000 km changes. Early chain failure is almost always linked to extended oil change intervals or wrong oil specification.
