What is a diagnostic check?

Today’s vehicles are manufactured with complex interrelated electronic systems. On-board computers continuously monitor and store information concerning the performance of these systems. If you see a warning light on the dashboard, this is because the computer has sensed a signal from one of the systems or components which has gone outside of its normal operating range. This is when your vehicle needs to be plugged in for a diagnostic check.

Your garage will have the specialist equipment need to communicate with your car's electronics. It will show them details of any faults reported by the car, and help them to understand exactly what the problem is that is causing a warning light to come on. They can then tell you how serious the problem is (or not!), and what they will need to do to fix the problem.

Driving in London

London is the most densely populated region in the UK, and so it presents challenges for motorists who need to get around the capital fast. On average, drivers in the London commute zone waste an extraordinary 82 hours a year to traffic congestion. Fifteen of the 25 most congested roads in the country are in London: Bedford Road in Clapham has been rated the worst, with Uxbridge Road in Southall and South Ealing and Eversholt Street in Camden also in the top 10.
