Car Diagnostics Garages in Lancashire

A warning light on the dashboard tells you the car's own computer has logged a fault, not what the fault is. A diagnostic check reads the stored fault codes and live data so the garage can find the cause before replacing parts. The garages on this page say on their own websites that they offer engine or warning-light diagnostics.

Ask what the check includes and whether the fee comes off the repair if you go ahead. The law says a garage must do the work with reasonable care and skill, and if no price was agreed you only have to pay a reasonable one, so agree the price in writing first. An MOT does not cover the condition of the engine, clutch or gearbox, so a recent pass does not rule out a fault.
