Vehicle Diagnostics

Using advanced diagnostic equipment, McMullan Auto Services offers vehicle diagnostics for mechanical and electronic faults. The team can investigate dashboard warning lights, engine issues, electrical faults and other vehicle problems, identify the likely source of the issue and advise on the repair required.

McMullan Auto Services uses quality replacement parts and can combine diagnostic testing with repair work, allowing many vehicle faults to be investigated and resolved through the same workshop.

Pre-MOT Checks & MOT Repairs

If your MOT is approaching, the garage provides pre-MOT checks and MOT repairs in Armagh. Qualified technicians can inspect the vehicle before the test and, where required, carry out servicing or repairs to address identified problems and help prepare the vehicle for MOT.

Specialist Diagnostic Capabilities

McMullan Auto Services uses Autologic independent diagnostic equipment for specialist fault finding and also offers programming of pre-owned control units.
