MOT
A1 Diagnostics is a fully approved MOT test centre. We can carry out servicing and repairs to get your car through its MOT. We also have a class 4 and 7 MOT test lane for fast, fair MOTs on a wide range of vehicle types.
Key Coding
Did you know the car is actually programmed to the key and not the key to the car? Main car dealers will tell you they have to code three keys for your vehicle, but A1 Diagnostics can program just the one key to help keep your costs down.
