ok i have a 99 b5 and there is a puddle under the driverseat. I dont know where it came from and it's starting to smell really really bad. I was wondering if anyone else had a problem with that or knew where the leak my be. Ive re-sealed any holes that I used to run wires through the firewall. Its just under the driver's seat. I can't seem to find the source. thanks for looking..
