“I’ve had two MOTs at A1 Diagnostics and I’ve had great experiences both times! Really nice, honest staff.”
Neil Ware Jones
“Repaired my turbo, I’m very happy with the service and team.”
“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”
“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
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.”
“Fantastic service. Polite & professional staff with a TV room ready with cartoons on to keep the little one entertained. I also got a free cuppa! Top service.”
“Thanks for getting me back on the road so quickly”
“Thank you guys so much for servicing my AUDI R8 so quickly, I will see you in the future for a service”
“Amazing service, staff are really friendly and helpful. Nothing was too much trouble.”
“Thank you for sorting my car out for me guys, I have to be honest, the surroundings, décor, waiting room and free coffee were all great, but what made it for me was the excellent service from polite, helpful, knowledgeable staff. From the moment I walked in I felt like a mate had just popped in to say hi – don’t change a thing, it’s awesome!”
“I just wanted to say a big thank you to Richard and the team at A1 Diagnostics for finally helping me to get my lovely little veteran MG back on the road! I am very grateful and will be recommending you to friends and family. Many thanks.”
“Many thanks for fixing my Honda Jazz. The Staff were very helpful and friendly. They explained the problem in detail before repairing the vehicle quickly. It was also very reasonably priced.”
“To A1, thank you for everything, my Mercedes is driving beautifully!”
