The following situation occured with my audi a8.
The fuel gauge shows empty, while the tank is full. No fault codes.
I already took the 4 sensors out of the tank, and the resistance of every sensor looks ok. Upper sensors are 70-157ohm. the lower sensors are 50-300ohm.
There are no fault codes. Fuel gauge just shows empty.
When doing the analog test with vcds the fuel gauge meter works.
The car has a diesel engine, but the gasonline version uses the same gauge senders.
Anyone experienced this problem?
