Check Engine Light
High priority warning
A check engine light can mean anything from a sensor fault to a more serious engine problem. ADL Mobile Mechanic provides on-site diagnostics across Shropshire to identify the cause before unnecessary parts are fitted.
Should I keep driving with the check engine light on?
If the check engine light is flashing, or the engine is misfiring, shaking or losing power, stop driving and call Aaron — continued use can damage the catalytic converter or engine. A steady light on an otherwise normal-running car is less immediately dangerous but should still be diagnosed soon; ignoring it for weeks often turns a small sensor job into a bigger repair. On a visit, Aaron scans fault codes, reviews live data, checks obvious causes such as loose fuel caps or worn ignition parts, and road-tests where safe. The aim is a confirmed fault and a sensible repair plan, not a cleared code that returns tomorrow. Shropshire coverage from Wem is roughly thirty miles — call or WhatsApp with the registration, which light is on and how the car behaves. Photos of the dashboard help when messaging, especially for intermittent faults.
What to do next
Do not ignore a check engine light, especially if the vehicle is misfiring, shaking, smoking, or has reduced power. If the vehicle feels unsafe to drive, stop and get advice before going further.
