Vehicle Diagnostics
Diagnostic scanning and fault-code investigation for a wide range of cars and vans.
Professional mobile vehicle diagnostics and fault finding in Stafford and across Staffordshire. JTW Performance can investigate warning lights, stored fault codes and vehicle running issues at your home, workplace or another suitable location.

A convenient mobile option when you need a vehicle fault investigated without arranging a trip to a workshop. JTW Performance provides diagnostics and fault finding throughout Stafford and surrounding Staffordshire areas.
Vehicle diagnostics can help identify stored fault codes and investigate symptoms such as warning lights, poor running, starting issues, loss of performance and other electronic or engine-management concerns. A diagnostic scan is a starting point for fault finding; further testing may be needed to identify the underlying cause.
Where practical, diagnostics can be carried out at your home or workplace. The vehicle needs to be accessible and parked in a suitable, safe location. If a fault requires workshop equipment or repairs beyond mobile diagnostics, we can explain the next sensible step.
JTW Performance also offers ECU remapping in Stafford. If a warning light or running issue is present, it is sensible to diagnose the vehicle before considering performance tuning.
