Beth Edwards said,

“I’ve had two MOTs at A1 Diagnostics and I’ve had great experiences both times! Really nice, honest staff.”

Neil Ware Jones said,

“Repaired my turbo, I’m very happy with the service and team.”

Karl Harris said,

“Wonderful people and service as always from A1 Diagnostics. My car had a whole host of engine problems but it’s now running like a dream. Thank you again”

Matthew Brown said,

“Really happy with my Fiat Punto repair after its MOT fail. I expected a fair old bill on this car due to its age but I was delighted with the cost. I’m also really happy with how clean the car was when I got it back. That’s probably the cleanest it’s ever been!”

Lucy Ann Evans said,

“I was sent here by the garage I bought my car from to resolve an issue with the brake pad warning light. A1 fixed this with a new set of brake pads all the way around. I have recently had another problem with a noise coming from the engine after a crash. I feel the garage went above their duties as not only did they identify and fix the problem, but they also helped with the insurance company and the Audi garage. Normally I don’t like going to garages, but A1 made me feel really welcome, and as a plus, there’s always a free coffee on offer 🙂 I definitely would recommend this garage.”
