From BAD TO WORSE. With Key Off I removed the Instrument Cluster to simply unplug and replug to rule out a lose or bad cluster connection and now my gauge cluster has gone haywire.

The problem is not coding then, I have owned the vehicle several years and have used Durametric on it 100+ times, those faults appeared when my door lock assembly became faulty. I am going to inspect the Instrument Cluster and wiring and then desolder the Instrument Cluster.

U0146 Gateway control unit communication
Possible fault causes:
- No power supply for Gateway control unit
- Incorrect coding of Gateway control unit
- Short circuit or open circuit of CAN Drive
- Gateway control unit faulty (in most cases the cause is incorrect coding and not the Gateway control unit!)U155 Instrument cluster, communication
Possible fault causes
- No power supply for instrument cluster
- Instrument cluster incorrectly coded
- Short circuit or open circuit in the CAN display
-J Instrument cluster faulty (in most cases the cause is not the instrument cluster but incorrect coding!)How can verify the correct coding? And can I decode the module using Durametrics? I don't have a CAN Pin Out OBD Tester so can't check the CAN Bus. I am able to access all modules including Gateway and Instrument Cluster so not a power or ground issue.

Greetings,
Need some help diagnosing to fault codes in my ECM Module.
2005 Porsche 997 Carrera S Cab
U0155: Lost communication with Instrument Cluster Control Cluster.
U0146: Lost communication with "Gateway A"
Searching Google only found two other Porsches with the same issue and they were undiagnosed. Now searching those faults individually found other vehicles had those faults when cracks developed in the Instrument Cluster solder joints, people disassembled their Instrument Clusters, resoldered all the joints and the fault went away.
Has anyone else had these faults or experience with them. I recently relocated from Arizona with glass smooth roads to the Los Angeles area and the roads are horrible!!! Just in the last 3-weeks my drivers door lock assembly failed and window goes up and down like crazy and difficult to lock door, I believe this failed due to the rough roads, these faults also developed at the same time, which leans me towards cracked solder joints in the Insteument Cluster. Car runs and drives fine, just have these faults now.
Sincerely,
Stephan

Thanks Ahsai, I have used them in the past. Got lucky and local Porsche Dealership gave me a good price. Installed today and shot a short video.

Greetings RennTech Community,
Seeking the best place at the lowest price to purchase an Air Oil Separator for my 2005 Carrera S 3.8. Pelican Part offers 99710703800 for $211 + Free Shipping but others have mentioned paying around $150+ for the 997.1 AOS. Can someone recommend where I can purchase it for the lowest price?
Thank You,
Stephan
