I have a 01 430 with about 67000mi, and the fuel gauge suddenly stopped working. With refueling the needle remained in the same spot and continued to drop to empty even though I filled up. It continues to do so even after several refuelings. It does not gradually climb after driving. I "rebooted" the car by disconnecting the battery, and this returned the fuel gauge to a normal operating pattern, until the next fill up, where it failed again to regester a full tank of fuel. This is the firsts MB I have owned and your site has been a big help. Thanks.............. 2/19/07 up date, after refueling a few times found out that if I don't top off the tank to the pump cut off, the gauge works just fine. So guess will put off the trip to the parts store or dealer for awhile.
