Dealer Level Car Diagnostics - Harrogate and Knaresborough

At Great North Auto Services, we use state-of-the-art diagnostic systems – the same technology used by franchised main dealers – giving us full access to fault codes, live data, and system information across a wide range of vehicles. We don’t guess. We find the cause, explain it clearly, and recommend the right fix.

A warning light on the dashboard rarely tells you exactly what’s wrong – it tells you something needs investigating. Accurate diagnostics are the difference between fixing the actual problem and replacing parts that didn’t need replacing.

When you might need a diagnostic check:

• Any warning light showing on the dashboard
• Unusual engine behaviour – misfires, hesitation, or rough running
• Poor fuel economy with no obvious cause
• Failed MOT on emissions or an engine management fault
• Electrical systems behaving unexpectedly
• Pre-purchase inspection on a used vehicle

Diagnostics at Great North Auto Services are more than just reading codes

Pulling a fault code is the starting point, not the conclusion. Our technicians interpret what the data is actually telling them – cross-referencing symptoms, live readings, and known issues for the vehicle – before making any recommendation. It’s a more thorough approach, and it saves our customers money in the long run.

Great North Auto Services is accredited by the Motor Ombudsman, the IMI, and 1link, giving you the assurance that your vehicle is in qualified, accountable hands.
