Our specialist diagnostic testing is like having a mobile mechanic that specialises in electronic control units to your door. We can perform a car or commercial diagnostic test to highlight any fault codes that may be stored in the ECU, should you have any fault codes we will provide you with a full report for you to take to your local garage or mechanic. We also are able to provide our own fitting service for most parts via either a “visit us” or a mobile service. Alternatively if you have had any parts fitted by a mechanic or garage that require calibration, coding or programming we can again provide a mobile service or a “visit us” diagnostic service for this to. 

Car diagnostic testing can be used to diagnose faults and erase fault code memory. With our specialist diagnostic equipment we can give you an expert opinion and guidance as to what the issue may be.
