Mercedes-Benz Timing chain replacement in Espoo, Helsinki and Vantaa

What this service includes

Mercedes-Benz Timing chain replacement is planned around the exact model, engine, equipment level, service history and driving profile. The aim is to define the real maintenance need, scope the job correctly and avoid both unnecessary parts replacement and under-servicing.

• Mercedes-Benz's M271 engine (C-Class, E-Class) has a known balance shaft sprocket wear issue that can cause serious engine damage. The OM651 diesel timing chain typically stretches from 150,000–200,000 km. We replace the full chain kit and inspect all balancer components.
• The M271 balance shaft sprocket is always renewed at the same time — it is as vulnerable as the main chain.
• Timing chain replacement (chain, tensioner and guides) – from 995 €
• Manufacturer OE timing chain kit – from 1 200 €
• Twin-cam diesel timing chain – from 1 500 €
• Engine run test and diagnostics included
• Symptoms, previous service records and relevant fault codes are reviewed before parts are ordered.
• The work scope is matched to manufacturer instructions, mileage, age and driving conditions.
• Parts, fluids, labour steps and risk items are confirmed with the customer before repair work begins.
• Where one symptom could come from several systems, we use inspection and measurements before recommending expensive components.

How the service is handled

The visit starts with an intake inspection and, where useful, a road test. We then define the required steps, source the correct parts and complete the approved work. If the inspection reveals an additional safety, emissions or drivability issue, we pause and quote the next step separately. At handover, we review what was done, what was found and what should be monitored next.
