Hi Andy just sent you a PM, JIMOh and welcome to the forum
I am a new member. I have two z3. aone is a 2.8 98 model in black and the other one is a 99 model in silver. I could do with some thought on why my fuel guage does not work on the 99z it is not the guage as i have tried another cluster so it is likely to be the sender itself or wiring. Does anyone know whether the sender is repairable or where to purchase a replacement.
