Great Service and 100% Genuine Great Service and 100% Genuine 5/5

We had our airmass meter repaired as part of the ECU and told locally it was £1400 to replace. I used ECU testing who firstly take the ECU and let you know every step of the way by phone and email if the ECU can be repaired. Once you confirm for the work to go ahead you will, just like advertised get an SMS or phone call every step of the way. I was so pleased with the service guarantee and communications ECU testing provided.

Stalling Mercedes cured. Stalling Mercedes cured. 5/5

My son bought an A class Mercedes which almost immediately developed a problem with stalling from idling. An independent diagnostics test revealed the mass air flow meter to be at fault. Prices quoted for a repair ran close to a £1000. After looking on the net I found ECU testing. The unit was refurbished for £145 plus vat . The unit was returned after only 3 days. The car is now running fine. I would have no hesitation in recommending them.

Love your work! Love your work! 5/5

A huge thank you to the ECU testing team. I sent my mass airflow meter to the other side of the world. It came back to me exactly as promised and worked as soon as it was back in my car. Your service saved me thousands of dollars & has my car back on the road in New Zealand. A huge thank you! Sarah M. Wellington, New Zealand.
