Appears that the system is leaking badly, although the motor is working ok . Does anyone know if this is covered under an Audi used warranty ? ( yes I can hear the laughing ) quoted £ 150 by local dealer ........

No idea on warranty, but I’d like to think so. If you’re spanner handy, these jobs are not difficult. Water reservoir normally accessed by removing road wheel, then inner wheel arch liner. Normally a series of Torx screws and a couple of 10mm hex nylon nuts.

If the reservoir has a crack, replace. Pump usually attaches with 12v supply, with rubber pipes. It could be leaking at a pipe attachment.

Main Audi dealer is £200 an hour, not including parts. This is bread and butter work for an independent garage you trust.

Thanks for the reply , if its covered on warranty which I hope so, no probs . Strange thing is I had an S7 a few years ago and the same thing happened with that car , but the repair was done whilst the car was in for service. I will see what they say when I take it in Friday morning .
