Hey all, was wondering if someone could perhaps shed some light on this. I've just returned from holiday so my B5 S4 has been sitting peacefully in the drive for about 2 weeks without moving a muscle. After returning, I've gone to start the car and probably left it idle for around 10 minutes.
After going out for a short drive and returning I've noticed a patch on the floor (about the size of a rugby ball... maybe bigger) which upon putting my finger in smelt strongly of petrol. At least one part of the patch was fresh.
Just had this checked out today and there is indeed a leak from the top of the fuel tank area, but for the last 2 weeks the car has been on less than 1/4 tank full. Fuel patch was at the back of the car, more to the driver side and around the fuel tank area. I can't figure out what could have happened here... I'm quite concerned! Any ideas?
