No, because you haven't given us nearly enough details. Petrol or diesel? Did it just stop or go into limp mode? Will the starter crank the engine or is there nothing at all?
Thanks for reply I'm not used to this my a3 diesel 2009 drove perfectly to work I returned to car I'n the rain put key I'n message on display brake failure drive carefully to mechanic, I turned key engine fired for 1sec. And stopped ,all engine fault lights still on when I try to start again it's the same procedure . Any comments would be welcome. Cape.
Have you posted on the Audi Forum. Last time I heard of this it was the pressure sensor in the ABS pump that had failed. Get the diagnostics checked out properly. Regards Peter
