ECU Testing & Repair in Kempton Park
Computer box and ECU fault assessment, repair and coding enquiries. Diagnose the problem before deciding on the repair.
We come to your location · Services only
The engine control unit (ECU), often called the computer box, gets blamed for many faults it didn’t cause. Low voltage, a poor earth, a corroded connector or a damaged wire can produce the same symptoms as a failed ECU.
We start by testing the ECU’s power, earth and communication circuits and scanning the vehicle’s systems. If the ECU itself is faulty, we explain the options, including repair, replacement and the coding or immobiliser matching a replacement unit may need.

Common questions
Does an ECU fault code mean the ECU is broken?
Not necessarily. Many ECU-related codes are caused by power supply, wiring or sensor faults. Testing those first can avoid an expensive replacement that does not fix the problem.
Can I fit a second-hand ECU?
Often not without extra work. Many ECUs are matched to the vehicle’s immobiliser and must be coded. A used unit with the wrong part number or software may not run the car.
Is ECU repair done on site?
Testing and many checks can be done at your vehicle. Repairs inside the ECU itself may need a separate repair stage. We confirm this once the fault has been assessed.
