ECU Repairs 

This customer called in after having his vehicle in at several garages and was unsure if the ECU was causing the faults on his vehicle. The customer reported to us the following symptoms:

• Running Rough
• Lack of Power
• Engine Hesitation
• Hard to Start

These are common symptoms of a failed ECU for this vehicle so we requested the customer send his ECM unit in for ECU Testing. His local garage removed the ECU and sent it to us along with the diagnostic report.

We connected the ECU up to our testing bench which can emulate the ECU being connected to a vehicle and run a cycle of programs which will simulate the different starting / driving conditions of the vehicle to determine when the faults occur. Our testing equipment very quickly picked up that the unit was faulty and we were able to identify the exact cause of the failure.

We notified the customer and he was happy for us to proceed with the repairs. We repaired the ECU and returned it to our customers garage who plugged it in and confirmed the vehicle was running perfectly. No programming was required as we retained all coding in the ECU. The repaired ECU was returned with our 12 month warranty.
