Frequently Asked Questions
What is the Mercedes timing chain issue?
Many M274 and M276 engines experience timing chain stretch and tensioner failure, causing a rattling noise on cold starts. If not addressed, it can lead to catastrophic engine damage. We replace with updated genuine parts.
How do I know if my Mercedes engine needs repair?
Warning signs include: Check engine light, unusual noises (rattling, knocking), oil consumption, loss of power, smoke from exhaust, or overheating. Early diagnosis can prevent major damage.
Is it worth rebuilding a Mercedes engine?
If your Mercedes is well-maintained otherwise, engine rebuilding is often more economical than replacing the vehicle. A properly rebuilt engine can last another 150,000+ km.
Do you repair diesel Mercedes engines?
Yes, we specialize in OM651 and OM654 diesel engines including injector replacement, DPF cleaning, EGR repairs, and turbocharger work.
How long does timing chain replacement take?
Timing chain replacement typically takes 2-3 days including proper testing. We don't rush this critical repair.
What warranty do you provide on engine repairs?
All engine repairs come with a 1-year warranty. Complete engine rebuilds carry a 2-year warranty covering parts and labor.
Customer Reviews
Timing chain issue was causing terrible rattle on cold starts. Metre Per Second replaced the complete kit with genuine parts. Engine is whisper quiet now. Excellent work at a fair price!
My E-Class needed major engine work - head gasket and turbo. The team handled everything professionally, explained the process, and delivered on time. Car runs perfectly now.
Oil consumption problem fixed by valve stem seal replacement. They saved me from a much more expensive repair that another workshop suggested. Honest and skilled team.
