We have been servicing vehicles for over twenty years at our award-winning independent garage based here in Cardiff. Pictured below.

We have received many five-star testimonials on Trust Pilot. Let’s take a look at three shown below.

“Took my BMW there after recommendation from my son, the ambience lights were not working, spoke to A1 Diagnostics and he recognised the fault straightaway, he ordered the parts from BMW, kept me in the loop as there was a delay of the parts coming from Germany, phoned me when the parts arrived and booked the car in within a couple of days. I dropped the car off in the morning and it was all done by midday, they even washed the car. From start to finish A1 Diagnostics went the extra mile with their friendly manner and professional touch, would highly recommend A1 to my family & friend’s.”

“Took my car in for a service to A1 diagnostics. An excellent service provided by the staff and mechanic who took care of my car. Very reasonable prices and excellent service as expected. Well done to the everyone at A1 diagnostic keep up the good work.”

“My father John Haines had an issue with the electrics on his jeep, and unable to get the AA to even come out. In desperation he contacted A1 Diagnostics. They were helpful, and nothing was too much trouble. I have to say, he found them outstanding and their work excellent. They resolved all the issues he had with the Jeep electrics. In fact, they sorted everything out and put his mind at ease. He will now be using them for all his future needs with the Jeep. Outstanding and excellent work”
