I took a C8 for a test drive which I have since bought. During the test drive, the engine management light came on and the control panel was displaying 'ANTIPOLLUTION FAULT'. This has been fixed by the dealer, but now, each time I accelerate, there is a beeping noise and the control panel is diplaying an image of the car with the front bonnet area of it highlighted. Can anyone please tell me what this might be???
