Durametric Code 1045 - Selector Lever Switch

[vrichmd]

My manual shift works intermittently and after driving for 20-30 minutes P-R-N-D will all light up.  Lights go out after car is turned off and restarted.  Tiptronic on steering wheel works fine and will shift into manual when selector is in manual, but intermittently switches back to automatic.  Sometimes, manual works fine with no problem.  I replaced the trim cover even though it wasn't broken and it didn't change anything.

 

Durametric gives me "1045 Selector lever switch - Implausible signal, test conditions are not-completed, fault is currently active and causing a DTC light"

 

Is this code for the selector switch on the side of the transmission or the microswitch at the shift lever?  Any other suggestions?

I sent you a PM.

PROBLEM SOLVED...Hopefully.  I got ready to delve into this earlier this morning and since I'm a firm believer in the KISS method, I disconnected the Tiptronic control unit and reconnected.  Now, the manual-automatic is working as it should and the fault is gone.  I'll go back and do a thorough cleaning of the pins in the connector, but I am hopeful that this was a simple fix.

The shift lever assembly is going bad is not un-common. Some have repaired their assemblies but if it faults again I'd just purchase a new one. Not too expensive from Sunset or Sonnen Porsche.

It looks like mine may have been corrosion on the pins of the control unit connector.  Still working fine as of today.

I had this same issue and the fault was the magnets on the circuit board under the shift lever

the circuit board had cracked allowing the magnets to get out of alignment and send false signals

I found a cut wire and another that was almost cut in the wiring harness going to the circuit board.

Where is the Tiptronic control unit located? I have same problem as you  

[vrichmd]

It is underneath the passenger seat.  The attached PDF shows all module locations.

Which circuit board, under the shifter or under the pass seat?
