NNN500020 ECU repair 5/5

Fantastic company do what they say they will do. Repaired my ECU in two days another company had said it was beyond economical repair, enough said.

Excellent service 5/5

ECU Testing could not have been better, throughout the process continual updates were provided and the final repair was excellent with the vehicle running better than ever. I will use ECU Testing again and would highly recommend them
