this is the text book example of what happens when the in-tank transfer fuel
pump dies. Have him check with the dealer, there is a recall on some sciroccos
and he might get a new one for free.

yes, our fuel pumps don't last, tell him to listen for the buzzing noise that
the pump makes, if there is no noise the pump is dead, if there is way too much
noise the pump is about to die. Have him check for any rust or dirt in the fuel
tank.

alot of the time the front windshield seal starts to leak water directly onto
the fuse box. This happened to me which made my flashers and my wipers short
out. Check the fuse box for any corrosion, all i did to fix it was scrape off
the corrosion in the fuse box and fix the windshield, haven't had a problem
since.
