    Hi i bought a A3 the other day its a A3 1.8T and has a all S3 bits on it, It is a 1998 and the in car heater is very weak?
    When you rev the car above 2000rpm it gets a little warm but on idle it goes stone cold i have changed the termostat and bled the system and still its the same i have also done a head gasget check and all is ok on that side of things?
    I dont know what else it could be, it has the digatal climate control and i dont know if that is the right 1 for the car as my friends one witch is the same model and age has the non digital ones????

    If anyone could help me that would be great

    Thanks
