ECU faults & repairs

Communication faults, no start or strange electrical behaviour. We diagnose ECU problems.

The engine control unit (ECU) runs your engine. When it, or the wiring and power supply around it, develops a fault you can get no-starts, cutting out, warning lights or modules that won't talk to each other. We test the wiring, power and communication before condemning any unit.

Signs you need this

  • Vehicle won't start or cuts out
  • 'No communication' with the ECU
  • Several unrelated warning lights at once
  • Faults after water damage or a jump start

What we do

  • Power, earth and wiring checks
  • CAN-bus and communication testing
  • ECU repair, replacement and coding
  • Other control modules (BCM, TCM and more)
How much? Every vehicle and fault is different, so we'll give you a price once we know what's wrong, always before any work starts.
