Hi Mick (assuming that's your name!!)

I've an newish (07) A3 doing exactly the same. I'm filling up with 1/2 a litre every week (500 miles). As it's under warranty, the dealer kept it over night to pressure test, but found nothing. I was asked to keep a diary (dates, amount filled) and go back in the new year for further investigation. I'll post the result when I get it. On another Audi forum, a guy had the same problem and it turned out to be a microscopic hole somewhere in the radiator. Seems possible

H thanks for the reply, i too took my A3 into the local Audi dealers for them to find nothing at all, and most surprising of all, i was charged nothing either, will keep forum posted should i ever find out.
