VW Audi Group Engine Management - Melksham

An engine management light usually means a sensor or system linked to the engine has detected a fault, and it’s worth having the code read as soon as possible to identify the cause.

At Audi VW Centre, we diagnose and repair engine management faults across most makes and models, using manufacturer-level diagnostic equipment to identify the exact issue rather than guessing.

Common causes of an engine management light

A number of issues can trigger the light, including:

• A faulty oxygen or emissions sensor.
• A loose, damaged or missing fuel cap.
• Worn ignition coils or spark plugs.
• A failing catalytic converter.
• Issues with the mass airflow sensor.
• Problems with the fuel or vacuum system.

Flashing versus steady warning lights

A steady engine management light usually indicates a fault that should be checked soon but doesn’t require you to stop immediately; however, a flashing light is more serious and often points to a misfire, which can cause damage to the catalytic converter if you continue driving. In this case, we’d recommend reducing your speed and having the car looked at as soon as possible.

How we diagnose engine management faults

We connect manufacturer-level diagnostic equipment to read the fault codes stored in the engine control unit, then carry out further checks to confirm the actual cause rather than relying on the code alone. Many faults share similar codes, so accurate diagnosis matters as much as the right equipment. Once we’ve identified the issue, we’ll explain what’s wrong in plain terms and provide a clear quote before any work begins.
