I have an X reg Audi A4. Yellow 'OK' illuminated momentarily when turning on ignition which I assume means all systems functioning correctly. However also have permanent yellow warning (depicting outline of an engine) does anyone know what this is indicating. An engine defect I would imagine however as I say, have OK disply also. Thanks

 

I have a yellow warning light looks like an engine with a K inside it. Peugeot 405 L Reg. Please don't tell me to buy a new car.
