Decided to keep the car...borescope is fine. I think the car knew I wanted to sell and the electrical gremlins came out.
Attached is the fault code scans.........PSM and PASM do not work. Heated seats do not work. Convertible top works.....

Might start with checking the battery's health with a battery tester at your local autoparts store.

If healthy, clear all of the codes, disconnect the negative cable from the battery for about 30' then reinstall. Objective is to reboot all of the modules (aka computers).

Tried all that several times and no impact.............

What aftermarket items are installed and tied into the canbus network? PCM/stereo, BT kit, 3-axis accelerometer for DSC contoller, etc?

Remove the negative battery cable. Follow the positive battery cable to the connector pin in frunk, release locking clip and slide off, look for corrosion on the pin and inside the female connector.

Follow the battery ground cable to the chassis. Is it tight and free of corrosion?

Idoktr

Installed new head unit 4 years ago without issue until now...........will try your suggestion. Thanks

Idoktr

There was some corrosion, cleaned it well and reattached but faults still there.............thanks for the help. will take for a drive later and see if driving helps clear codes............

When my spoiler button and PSM button stopped working, it was the switch module. After 2 weeks of the dealer tracing wiring (switch unit checked fine with ohmmeter), they replaced the switch anyway and the problem was fixed. Apparently there was a burned trace in the switch that could not handle the real signals.

Also check fuses....often over looked but you may have popped a fuse.

Your car thought it was for sale, this is part of the Porsche Retribution Package.....tell her she isn't going anywhere take her for a spirited drive to get her back in good graces.

I have been talking nicely to her for the past 2 week and gave her a good warm bath !!!!!!!

Idoktr

Can you give me a pert number or link please?

I’ve been looking for the paperwork and have not found it yet. I must have mis-filed it. If it is the same as the Cayman switch, it would be like this one:

FIXED !!!!!!!!!!!!!!!!!!!!!! Not sure how but applied these suggestions.

1. new ignition switch-Spain model
2. Cleaned corrosion from positive battery terminal at the firewall.
3. Checked all fuses-all ok
4. Reset system with battery disconnect
5. Checked battery heath-all good

THANKS FOR ALL THE SUGGESTIONS !!!!!!!!!!! KEEPING THE CAR !!!!!!!!!!!!!!!

CAVU

you better be REALLY nice to her on the next few dates with her (car). She is convinced that it was all YOUR fault no matter what you did to fix it!!!

Idoktr

I already have been very nice to her. A few warm, soapy baths and lots of sweet talk. I think she is convinced she is staying put (which she is !)
