Diagnostics and ECU repair
A warning light tells you something’s wrong, not what. We read the fault codes and the live data at your home or workplace, find the cause, and explain the fix before any work is done.
Warning light on? Tap the one you can see.
We’ll tell you what it usually means and who to send it to.
Engine management light
- What it usually means
- The engine computer has stored a fault. It could be a sensor, boost, fuelling or emissions problem, so the light on its own doesn't tell you which.
- What we do
- We read the fault codes and the live data to find the cause, then explain the fix before any work is done.
What we look at
- Fault codes and live data We look at what the engine is actually doing, not just the code it’s stored.
- Limp mode and power loss We find out why the engine cut its own power to protect itself.
- Rough running and smoke Misfires, hesitation and smoke all leave clues in the live data.
- Gearbox faults We read the gearbox control unit and tell you whether it’s a software job or a mechanical one.
ECU and module work
- ECU programming Updating or reprogramming engine control unit software.
- ECU repair Finding and fixing faults in the engine control unit, depending on the fault.
- BCM repair and cloning Body control module faults, and moving data across to a replacement unit.
- Module coding and programming Coding replacement modules so they work with the rest of the car.
- Electrical fault finding Tracing electrical faults with the diagnostic tools and live data.
- Instrument cluster repair Cluster faults, and setting a replacement cluster up for the car.

Questions people ask
Can’t see yours? Send it to us on WhatsApp.
Can you just clear the light?
We can clear stored codes once the fault is fixed. Clearing a code without fixing the cause only means the light comes back.
Do you come to me?
Yes. Diagnostics are done at your home, workplace or yard across the West Midlands. We’re based in Willenhall.
Will you remap the car at the same time?
Only once it’s healthy. A remap isn’t a fix for a fault, so the fault comes first.
What if it turns out to be the DPF or AdBlue?
We’ll tell you, and point you to our sister companies: DPF Clean Specialist or Repair My AdBlue.
