    I have a 2002 a4 cab and I keep going low on coolant nearly every day. I now realise there is a crack on the plastic cover underneath the front of the car and thats where it looks to be leaking from. Does anybody what it could be and how much to repair?:confused:

    The plastic thing underneath is the undertray, this will have nothing to do with water leak, it just looks like its leaking from it.

    What engine do you have, some weak points I have found on the 1.8T are

    On the rear of the engine there is a jacket that divides up the water outlets, this is prone to splitting, it's a shite job to change, cost me approx 150 quid as mine went big time.

    On the front of the car under the radiator is a metal pipe that runs most of the way accross the front, it rusts and splits

    Could be a pipe has split, you can see most of the pipes on 1.8t have a prod about.

    Thats what went on mine, the rubber seal went hard and cracked,it was fully draining all coolant daily. Cost me about £80 to have it replaced and was apparently a pig of a job.

    i had the same problem with my audi there flange in the middle of the engine, after a while the flange will crack due to the heat from the engine.This common with most a4.so it should be ok.

    Sent my car into audi today for assesment. Told them when i went to see my car after the smash there was loads of water coming out the front. They said they'll look at it and deal with it,:happy: And they gave me a 56 plate A4 2.0TDi S-Line as a courtesy - NICE!
