Well, while driving home I got the PSM workshop message. After a couple of minutes of driving, when coming to a stop, it would go very slowly and then finally kick in. Once home, hooked up the durametric. Following codes

470 CAN comfort in signal wire operation

778 Steering signal sensor

1314 DME control module

819 air conditioning sensor open circuit

1336 can comfort off

470 can comfort off

P0700. transmission control implausible signal

P0050 heater control bank 2 sensor test not completed

P2680 fuel pump control no signal

P0011 cam position timing over

P2186 throttle pedal implausible signal

P2174 throttle position implausible



I cleared all codes and only the 470 code remained. I disconnected the negative battery cable for a few minutes and declared using Durametric. Drove fine. After stopping at the store, turning off the car and then restarted the Psm code came back up.



What the heck is going on?

FAULT CODE 1314 -DME CONTROL MODULE

Possible cause of fault
 Signal from DME control module does not correspond to expected signal (please read out fault memory).
 Signal from DME control module does not appear on CAN drive (no signal/communication).

Affected pins
PSM control module plug:
 Pin 15 'CAN drive (low)'
 Pin 11 'CAN drive (high)'

NOTE: If there is no incoming signal via the CAN drive using several control modules,
the CAN drive must be checked for open or short circuits.

What diagnostic tool you use?

I have to ask you to be more specific!
So once again, from which modules you read those errors? PSM? Gateway?...

You can test all CAN lines from gateway, (using the right diagnostic tool)and see in which line is problem.

From his first post he's using the Durametric Diagnostic Tool. It's an aftermarket tool designed specifically for Porsche vehicles.

Funny, I got that message last night on my car after installing my methanol injection. I came here to see if there are any common issues. I'm hoping that I just unplugged something and forgot about it.

Sorry, I missed that.
