I have a 2005 A4, 2.0 TDI. Recently bought from a local dealer.
Car starts perfect from cold, but when the engine is heated up it turns over a few times before firing and when it does fire the bremse light flashes a few times. What could be the problem? Car is still under warranty so I want to get it sorted ASAP. It has been back in the garage and they changed the thermostat sensor but it didn't work!
Any help would be appreciated.
