I had the same problem with my gas gauge, after filling up my gas gauge was going to empty for about 20 to 25 miles. If I fill up too much, the problem comes back. If I stop at the first click the gas gauge works fine. I was advised by my mechanic that the floater near to the tank is getting stuck if I fill up all the way to the top. To replace the floater you are looking at $115 for the part and $65 for labor. I hope this helps. __________________ 1989 E30 325is 5s Coupe Zinnoberrot 1991 E30 325i Auto Coupe Schwartz 1991 E30 325is 5s Coupe Hellrot 1995 318ti E36 Alpine White III DASC (RIP) 1996 328i 4Dr Artic Silver (RIP) 1999 M3 Estoril Blue Metallic RMS Vortech SC 2001 325i E46 Alpine White - Sports Package (SOLD) 2005 E46 M3 Coupe SMG |
