Stop little problems becoming big ones

Worrying warning lights on your dashboard? Let Halfords Autocentres' ATA-trained technicians quickly identify the problem and stop costly component failures.

We use state-of-the-art car diagnostic test equipment and our high-level technical training means we can make sense of baffling fault codes and advise on any necessary repairs.

You'll always pay a great price for our comprehensive vehicle diagnostics check - and the peace of mind is priceless.


All modern cars contain on-board computers that monitor or control things like emissions levels, engine temperature and even windscreen wipers. When things go wrong, these computers produce error codes which can only be read with vehicle diagnostics equipment. You may see a warning light on your dashboard, but these only give a small part of the full picture.

Our car diagnostic check picks up these errors and identifies what they mean, so component failures can be prevented before they lead to further damage or expensive repairs!

You don't have to go to a dealership to find faults. We can carry out diagnostic testing for almost all makes and model of car, and the service is available in all our autocentres.

The cost of our car diagnostics test is fixed - the price you see is the price you pay. If we discover problems with your engine or other components, we'll provide you with a free, no-obligation repair quote upfront.
