glow plugs light flashing


Registered User
Hi, I've a 2003 A3 8l TDi 130. On the way home the glow plug lamp started flashing, the handbook states that I need to take it to a dealer to get the fault codes read. Anybody else had this fault/know waht it could be? The car is running fine, no loss of power or anything

Might be the brake lights. IIRC, glow plug light is used to indicate a number of problems and brake lights/switch is one of them.
