Motorsector Streatham · Streatham, SW16 5LU
ECU testing and coding
An ECU fault should be confirmed before the unit is repaired or replaced. MotorSector can test relevant power, earth, wiring and communication conditions, then advise whether coding, coding where supported, repair or replacement is appropriate for a supported vehicle.
Inspected, estimated and approved before work begins at our Streatham workshop.
