9023 Fuel level display
Problem Remedy
If the power supply is interrupted by a discharged or
disconnected battery with the tank containing less than
19 l, the calculated value for the range on remaining
fuel in the instrument cluster will be incorrect or
deleted. •
If the tank contains less than 10 l, it is possible that the
fuel level warning light is no longer activated. •
If the power supply is restored with the fuel level at
less than 19 l, it is possible that the fuel level display
may subsequently display too much. •
This may lead to the vehicle breaking down.
Refill at least 19 l of fuel; then the
fuel level sensor is in operating
range and its display precision is
guaranteed.

9120 Radio
Problem Remedy
The radio reverts to the Code function when the battery
is disconnected and is thus no longer ready for operation.
1. Input the radio code.
2. If the code card is unavailable, the radio
code can also be read from the DME
control module (under "Vehicle data").
3. This code is also available from the
Porsche IPAS.
