ABS repair 5/5

By far the best repair business by a mile, I've used ECU Testing pretty much from when they started I have never had a single problem with any repair they have carried out, I have been in the motor trade for 55 years and in the diagnostic business for 50 years I wouldn't hesitate to recommend their work to anyone, they are my first choice whenever I need a ECU repair of any description. Kind Regards Kev Egerton.

Non start no coms to ecu 5/5

Car experiencing non start fault no communication to ecu or any of the can bus system. Sent off ecu and received it back the same week along with them finding a can bus fault within the ecu. Refitted and fault hasn’t return, driving it for a month and it starts every time with no codes. Would recommend! Save her from getting parted out!
