Removing and installing gear selector position P switch F305 (vehicles up to 11.2005) — AUDI

Removing and installing
gear selector position P switch
F305
(vehicles up to 11.2005)
The
gear selector position P switch
F305
consists of two microswitches. The two microswitches provide the signal required by the electronic ignition key removal lock to release the key only in selector position P.
The first switch is closed when the
selector lever lock solenoid
N110
is not actuated in selector position
“P”
, (brake pedal not depressed) and the manual release of the selector lever below the ashtray is not operated.
The second switch is closed when the button on the selector lever handle in selector position
“P”
is not operated.
Note the following points before renewing
gear selector position P switch
F305
:
The two switches are connected in series, i.e. both switches must be closed before the ignition key can be removed. The switches can be checked with a diagnostic tester, e.g.
vehicle diagnostic, testing and information system
VAS 5051B
in the Guided Fault Finding mode. After performing the vehicle system test, select the test program
F305 - Gear selector position P switch
(Powertrain / multitronic 01J, front-wheel drive / 01 - systems capable of self-diagnosis / 02 - gearbox electronics / electrical components).
It is also possible to perform an electrical check on the switches. When performing a continuity test using a multimeter, note that the resistance is approx. 470 Ohm with both switches closed.
