DiagnosticsFind the fault first
One warning light can mean twenty different things. A code is a starting point, not an answer — it tells us which circuit is unhappy, not which part has failed. Everything we replace is replaced because we proved it was the cause.

A code for a lean mixture can be a leaking hose, a tired sensor, a sticking valve or a blocked filter. A code naming a sensor very often means the sensor is reporting something the rest of the engine is doing wrong, and it is perfectly healthy itself.
Replacing the part named in the code is how people end up paying for three parts and still having the fault. We read the codes, then read the live data around them, then test the circuit before anything is ordered.
The faults we chase most
Engine management lights and limp mode on Sprinters, Masters, Movanos and NV400s. Loss of power that comes and goes. Rough running when cold. Emissions and exhaust system warnings.
Electrical faults with no light at all: a van that will not start on some mornings, a battery flat after standing, a component that works until the vehicle hits a bump.
Intermittent faults are the ones worth telling us the story of — when it happens, how warm the engine is, whether it is wet, whether the van is loaded. That description often saves an hour of testing.
What you get at the end
A plain explanation of what is causing the fault, what it will take to put right, and what happens if it is left. If the repair turns out to need a part, and it is a part we hold for your van, it can usually be fitted in the same visit.
