Diagnostics

At Autofit Garage Services, we have dealer-level diagnostic capability at our disposal. If you’ve got a warning lamp active on your dashboard, or notice anything out of the ordinary with your car, don’t risk causing damage, get in touch.

All of today’s modern cars are fitted with computers which control and monitor many functions of the vehicle. Serious engine faults to electrical failures such as air bags, traction control, ABS, ESP or even your alternator, are all monitored by your car’s onboard computer.

 

Don’t ignore warning lights!
When you see a warning light on your dashboard, it is because your car’s computer has detected a component or system malfunction and created an error code.

Using our advanced and state-of-the-art diagnostic equipment, we are able to read and translate these codes and find out exactly where the problem is.


FAQ – Diagnostic Charges/Faulting


I have what I think may be a warning light on my dash. I’m not sure what it is. Can you help?

If you have a light on your dash that didn’t used to be there, the chances are it is a system warning of some sort. Please don’t hesitate to get in touch or drop in, and we will let you know what the light on your dash represents and will advise upon further action, if required.


Why do I need a diagnostic check?

This is to save on chargeable labour time and is used to determine where the fault is on your vehicle. It is the first stage in diagnosis of any modern engine management system, airbag, ABS or any other warning light fault.


Will my car be fixed after a diagnostic check?

No. A diagnostic check does not repair or change anything on the vehicle; it will be exactly the same as before. The process purely assists us in determining where the fault lies.


What do I get when charged for a diagnostic check?

A machine to code-read and a live data check on your vehicle’s ECU (engine control unit), and approximately half an hour of a technician’s time with further faulting. The results can be interpreted by a technician, who will then advise you on the appropriate next stage. This is usually where an estimate of the full cost of repairs can be given.


How long will it take?

The vehicle is generally needed for up to an hour. However, it is sometimes possible for a result to be available in less than half an hour.


How much does it cost?

A diagnostic check/faulting costs £35 + VAT (£42 including VAT). This covers both the use of the diagnostic equipment and the technician’s time.


If no fault codes are found for my car, have I wasted my money?

No. Occasionally a diagnostic check does not produce a definitive outcome or any fault codes, but it does not mean it was a waste of money. The process still allows our technicians to check live data, and eliminates a number of problems such as sensor faults. It usually directs the technician towards a mechanical fault rather than an electrical one. In this instance, further investigation time may be required in order to produce an estimate.
