Vehicle diagnostics
near St Neots
Diagnostic testing identifies the cause of a fault before parts are replaced. A fault code is a starting point; it does not, on its own, prove which component has failed.

Fault codes and live data
A warning light can be caused by several different faults. Code scanning records what the control unit has detected. Live data and targeted tests help establish whether a sensor, wiring, mechanical condition or another system is responsible.
Information that helps diagnosis

Work included
- Diagnostic fault-code scanning and live-data analysis
