Gas Gauge Problem
Bought a 2003 Z4 2.5i from a dealer and the gas gauge didn't work; it only would move to half full when it was filled.
The dealer got a new sender unit (connected to the fuel pump - more than $400) but on further inspection the mechanic saw another sender in the tank.
When he questioned the BMW dealership about this, they told him it is a programming problem.
The dealer has been fine paying for everything, but I am left wondering if this is a common problem with the Z4, and if it is a programming problem
Thanks in advance for any info.
