Version coding Signal implausible


Possible causes, elimination, notes

Fault effect:
Reduced driving program.

NOTE: As transmission damage can result if the control modules are confused, there is a code in the vehicle wiring harness that must agree with the code programmed in the Tiptronic control module.










1. Use the Porsche System Tester 2 (Control modules/Identification) to check whether the prescribed control module is installed. (Refer to the parts catalog for details of the allocation.)
2. Check whether ground is connected to control module connector pin 12. If this is the case, the control module is faulty.
3. Check wire from control module connector pin 12 to ground point 9 for open circuit.

NOTE: Ground point 9 (MP 9) is located in the passenger compartment behind the right-hand spring strut attachment.
