I have had a problem with my a3 1.8t agu in the last couple of days it started with struggling to start and having a ticking noise coming feom inside and under the bonnet. i had a coolant tenp sensor fault which i changed today with no luck.
When i got the car started it sometimes cut out and on trying to restart it, it would struggle and backfire and not start. I have managed to pin point the ticking noise inside the cabin to be the fuel pump relay to be ticking but cant solve why it is and if thats the reason my car wont start and stay on.
Thanks in advance grant
