I had a serious electrical problem with indicators brake lights & main beam. Took my car to A1 Diagnostics who again explained the problem. It has been repaired and I am truly thankful. Awesome service.”

“Dropped the car off Monday morning non-starting with engine management issues. Diagnosed, parts replaced and vehicle washed working fine on Tuesday. Fantastic service, really nice staff. Booking a service there in the next week or so.”
Leigh said.
“This is the second time I have used this company. Just done a timing chain on a R57 Mini. Fantastic service and washed and hoovered the car. Highly recommended!”
Bizz Needs said.
“Great service and honest garage. Had my car looked at by A1 Diagnostics – had a fault with a misfire on the car. My local garage told me it was going to cost a lot of money. However £75 later with A1 the car was fixed and cheaper than what the original quote was. Highly recommended 10/10!”
Gareth said.
“Amazing service as always… had problems with other garages. But these boys sorted it straight away.”
Mike said.
“Had a problem with my MK7 Golf GTD yesterday that caused the car to go into limp mode. A1 managed to fit me in today and I’m back on the road! Big thanks to the great mechanics who found that a wire had broken which they went on to fix.”

Our labour rates are much more affordable than main dealers, you could be paying up to £50 an hour more for your vehicle to be serviced if you go to a main dealer, and if the job is a long one and takes all day, you could be paying up to £500 more even before you pay for the parts needed to repair the vehicle.
