Mercedes Vito Specialist
Vito Servicing
W639 • W447 • OM651 • OM622 • OM654 • Fitted at your door
From £175+ VAT · Fixed price · We come to you
The Mercedes Vito is the mid-size workhorse of choice for tradespeople, taxi operators, and courier companies across Kent and South East London. W639 models use the OM651 engine, while the W447 added the more compact OM622 and later the OM654. Both generations use the ASSYST service system and require the MB 229.51 or 229.52 oil specification. Common fault patterns include injector seal failure on high-mileage OM651 units, turbo actuator sticking on W447 models, and DPF soot loading on vans doing short urban runs. Every service ends with a written findings report confirming work done, fluid specs used, and any advisory items.
The Vito is everywhere - and it needs looking after
The Mercedes Vito is the go-to mid-size van for tradespeople, taxi firms, courier companies, and anyone who needs something bigger than a car but more nimble than a Sprinter. It works hard, covers serious miles, and deserves proper maintenance.
Whether you're running a W639 with the older OM651 engine or a newer W447 with the compact OM622 or OM654, we bring the correct parts, the right oil spec, and dealer-level diagnostic equipment to your door.
No workshop drop-off. No lost working day. Fixed-price servicing you can budget for.
Tradespeople
Plumbers, electricians, builders - your Vito is your mobile office. We service it at your yard or customer site.
Taxi / Private Hire
Vito Tourer owners - we service around your schedule. Early mornings, evenings, or weekends available.
Courier / Delivery
High-mileage Vitos need frequent attention. ASSYST may trigger earlier - we keep you on top of it.
Genuine Mercedes parts, every time
Vito servicing uses genuine Mercedes parts with the correct MB 229.51 oil specification for OM651, OM622, and OM654 engines. OEM filter housings, fresh sump washers, and pre-ordered parts for your exact W639 or W447 variant, so your high-mileage workhorse gets the same quality as a dealer visit, at your door.

Common Vito issues we catch during servicing
Because we run a full diagnostic scan alongside every service, we regularly catch developing faults before they become expensive problems. Here are the most common Vito-specific issues we find:
- Injector seal failure (black death): Carbon build-up around injectors on OM651 - caught early, it’s a seal replacement. Left late, it’s injector removal and carbon cleanup.
- Turbo actuator sticking: Common on W447 OM651 engines. Shows as reduced power or limp mode. We can test actuator movement via diagnostics.
- Glow plug failure: Hard starting in cold weather. We test each glow plug circuit during a major service and flag any failures.
- DPF soot loading: Vitos doing short runs build up DPF soot quickly. We read soot levels and can force a regeneration if needed.
A note on dual-clutch transmissions
Some W447 Vitos are fitted with the 7G-DCT dual-clutch transmission. This gearbox has specific fluid requirements and a service interval that's separate from the engine service. If you're unsure whether your Vito has a DCT or the standard 7G-TRONIC torque converter, send us your reg and we'll confirm.
We can perform transmission fluid changes alongside regular servicing - just ask when booking.
