Diagnostic Services


Every modern car has a standardized connector that allows us to connect our specialist computer to. Using this standardized platform, we have the ability to constantly monitor performance and connect into the car’s computers as it is running. The result is we can get a diagnosis in less than 20 minutes and progress through fixing the problem.
