Auto Electrics in Cardiff - SWSS BMW
A yellow warning light will appear on your dashboard if there are any faults related to your ECU (computerised engine control unit), engine or exhaust system. Your car may still drive perfectly but you should definitely have it checked out by our tech team at SWSS BMW – we’ll run a full diagnostic check at our workshop in Cardiff, and advise you on the best course of action to fix the fault.
If the red light is illuminated it’s a sign that there’s a serious issue with your car’s cooling system; if this happens, continuing to drive could result in major engine damage so make sure you get in touch with our team at SWSS BMW straight away.
SWSS BMW are independent BMW specialists; we provide unbeatable quality BMW MOTs, repairs and services, giving you the main dealer level experience but at a fraction of the cost.
