Vehicle Diagnostics FAQ's

What is a diagnostics check?

If a warning light or fault code has appeared on your dashboard, a diagnostics test can help identify and trouble-shoot potential issues. Using the latest vehicle diagnostics, we can read faults shown on your vehicle and either clear the fault memory or configure replacement parts. We can read faults on almost every make and model of vehicle. Our aim is to find your fault more quickly resulting in lower labour charges.
At John Delany Motors we use state of the art Bosch, Autologic & Mercedes-Benz equipment for vehicle diagnostics which can read the engine fault codes in your ECU’s memory. We operate dealer level equipment allowing us full access to all control units and vehicle information. With direct links to the manufacturers, we are able to carry out software updates and re-programming, keeping up to date with the latest changes.
Our fully-trained technicians can then suggest any necessary repairs to get you back on the road and rectify the error. There’s no need to pay vehicle dealership prices for your diagnostics check next time a dashboard warning light appears in your car.

I have a warning light on my dashboard, how do I know how important it is?

It’s always a good idea to keep your vehicle handbook in your car as it should give you a detailed explanation of the warning lights and what action you should take.

It is important to know whether a warning light requires immediate attention or if your vehicle is safe to drive and requires investigation in the near future. If your vehicle is displaying a warning light find a safe place to stop, turn the ignition off and remove the key for 5 minutes. If the fault is still there when you restart the car then give us a call.
