Possible causes, elimination, notes

NOTE: The functions of the solenoid valves (SVs) can be checked with the Porsche System Tester 2 (Drive links/ Solenoid valves 1, 2, 3). The activation pulses of the valves can be heard as a clicking sound near the transmission.
  1. Check function of the SVs with the Tester.
  2. Check SV with wiring. To do this, connect ohmmeter to the control module connector and measure the resistance:
    1. SV1 = Pin 52 and pin 30
    2. SV2 = Pin 52 and pin 33
    3. SV3 = Pin 52 and pin 32

    Nominal value: 24 ... 36 ohm

  3. Check wiring from the control module connector pins 30, 32 and 33 to the 16-pole transmission connector pins 8, 4 and 9 for continuity, short to ground and short to B+.
  4. Check SV. To do this, remove the ATF pan, disconnect plug connection on the SV and measure the resistance.

    Nominal value: 24 ... 36 ohm
