What the known faults on this Mercedes-Benz V-Class typically cost to put right at a UK independent garage · use the figures to price risk before you bid, and to justify a reduction when something shows up on inspection.
The single priciest documented job on the 2014–2025 Mercedes-Benz V-Class is timing chain, tensioner & guides at £900–£2,400. Few cars need every repair listed here · treat £2,150–£9,450 as the full exposure if one arrived with all of them.
Metallic rattling noise from the rear of the engine on cold start, indicating timing chain stretch on the 2.1-litre OM651 diesel.
Inspect · Ensure the engine is completely cold. Open the bonnet, start the engine, and listen closely at the bulkhead for a sharp metallic rattle lasting 3-5 seconds.
