I've been looking for a leak in my Avant for a few weeks now. On removing the scuttle panel as one of the first checks (engine drains) I realised all of the plastic screws are chewed by the previous owner and were just sitting in there loose (I removed the main screw and the rest just fell out). The tray itself is fine. I was wondering if the screw sets can be bought separately, if I can use any other screws, or if the whole thing has to replaced. I thought I saw some online but I can't find anything today.
