Fleet & Commercial Van Repair
In our experience the Sprinter is the most reliable van on the road. The diesel engines and transmissions are robust, payload and towing are excellent, and they are efficient for their size.
The Sprinter is a premium platform, and it rewards precise, by-the-book care. Many shops will not take them on. We do, and we follow the Mercedes-specific procedures that keep them running at their best.
NOx sensors, DEF tank heaters, and crystallized DEF at the injector are common. A critical fault starts a 'no restart' countdown, and when it hits zero the van will not start until it is fixed and cleared with Mercedes-level diagnostics.
Short trips and city routes keep the DPF from getting hot enough to burn off soot, leading to forced regens, cleaning, or replacement.
On the OM642 V6 the rubber oil cooler seals harden and leak. The cooler sits in the engine valley under the intake and turbo, so a cheap seal becomes a big labor job. We do it right the first time.
The flex pipe near the turbo and catalytic converter cracks from vibration and heat, then blasts hot exhaust into the engine bay, melting wiring, DEF lines, and sensors.

Sample data for illustration
Service intervals set from your routes, loads, and mileage, not a generic schedule. Fewer breakdowns and less downtime.
Every service we do on your Sprinters goes on record. Clean, documented history makes audits easier and helps resale value when it is time to cycle a van out.
See what we see before you approve anything. Every item is rated so you know what is urgent and what can wait.
That is the DEF/SCR start countdown. It means the emissions system found a critical fault. Get it in before it reaches zero, or the van will not start.
Not properly. Sprinters need Mercedes-capable diagnostics, and maintenance has to be logged and reset in the van's modules. Many shops will not work on them.
If the service was not reset in the computer, the engine keeps running on old parameters, like a clogged air filter it no longer has. That can cause drivability problems.
For fleets, yes. Kept on schedule, the engines and transmissions are built for long commercial duty.
