Check a Mercedes-Benz Vito advert (free) →The Mercedes-Benz Vito has 2 known faults in our database across 2 generations, 2 of them rated high severity. The most serious are fuel system (piezo Delphi fuel injector failure leading to limp mode and severe misfires) and engine (timing chain stretch (rear-mounted chain) resulting in engine rattle and potential failure). None of them makes the car a bad buy on its own; the risk is a seller who knows and says nothing.
That is a count of the faults we hold, not a reliability score. Popular cars get written about more, and a newer generation has had less time to show its faults.
No year is a write-off on its own. What matters is which serious faults a given year and engine can have, and whether the car in front of you has had them fixed.
Each one is set out in full below, with the symptoms, the typical mileage and a rough repair cost.
Sellers rarely admit these faults outright

The OM651 2.1 CDI uses a rear-mounted timing chain, fitted to the Sprinter W906 and Vito/V-Class W447 from 2008. It stretches typically at 100,000-150,000 km, sooner in commercial vans subjected to hard use or extended oil intervals. Listen for a harsh rattle on cold start that clears after 10-20 seconds.
Always confirm against the vehicle handbook. Intervals vary by engine, and several manufacturers revised theirs after failures in service.
No Mercedes-Benz Vito year is a write-off, but the W639 (2003 to 2014) carries the most serious faults: fuel system and engine. The W447 (2014 on) has none rated high severity. Year matters less than whether the specific car has had the known fixes, so check the history for them.
Ask the seller about the fuel system and engine faults on this page and whether they have been fixed, with invoices. On the test drive watch for engine management light and rattle on cold start. Read the MOT history for repeat advisories, then paste the advert into the free check, which reads it against its known faults before you travel. Check a Mercedes-Benz Vito advert →
