Hello,

My 996 (03' C4 cabrio) is having a stupid problem when the fuel level drops below 1/4 of the tank. The board computer states that there is no fuel inside the tank, so the remaining range is 0 (three dashes). Same indication I get from the PCMII b.c If I put less than 30 liters of fuel it still shows that its empty (three dashes). Most of the times if I fill it up it reads correctly, till the level drops below 1/4 again. As you understand, it works great when I go to the dealer Is it from the fuel level sender or from the gauge it self ?

 

I recall the dealer telling me some 996's have a fuel sender problem (or something like that). Might want to go to renntech.org and look at the TSB's.

 

Are these accessible to anyone ???

 

After just speaking to my Contact at P-car, They will replace the gauge cluster, it is a very well know problem, in fact mine was changed after the first fillup of fuel, they will try and update the ecu, if that fails new cluster you will get!
