Dealer notified me Friday that the recall for AH08 is complete. The camshaft controllers were not replaced, just the pan-head bolts. I am okay with this. The engine is running great. I will pick it up next week after they take care of a few other items. In the meantime, I thought I would prepare a comparison of the parts between the two campaigns.
If anyone has their controllers replaced under AH08, please upload your parts list. I can then update the comparison.
I did not see where Porsche rolled part numbers from WC-22. The pan-head part number shows up on a dealer's parts portal but it provides no history.
Porsche has rolled the camshaft controller three times. 948-105-051-23 is the latest. Prior versions are 948-105-051-21, 948-105-051-22

It doesnt look great that Porsche are still struggling to get parts, but it does seem that it starting to happen.

Oh, now thats interesting! What happened? I took the time to register the car with PCNA and had to provide proof that I owned the thing (like purchase documentation). Still didnt hear anything from them!

Contacted my dealer last evening. I should be bringing it in for the AH08 recall next week pending availability of a loaner. SA says they've done a couple at the dealer already. SA also mentioned they have it listed as a 5 hour job according to their internal AH08 documentation. They'll also once again look into the intermittent extreme cold weather coolant drip issue while it's there for the AH08 recall. More to come...

I brought in my CTT to the dealer today to have some warranty items taken care of (I have 1 month of CPO warranty left) and to have the AH08 recall done. I asked my service advisor if it was just replacing the bolts with a newer version and she said the techs will check to see if the existing bolts are loose. If loose, they will replace the camshaft and bolts. If they aren't loose, they will just replace the bolts. I'll post a copy of the parts used as soon as I get my car back from the dealer.

So it's interesting now that the recall work is happening, to hear that these infamous bad bolts ARE able to be extracted from the controllers. The early theory before AH08 even came about was that the bolts could probably not be removed, and may have been loctited in or something similar from the factory. It would be interesting just to see the process they use to pull the old bolts out.
In any case, just glad to see this progressing and making this issue a thing of the past. Mine should be going in Monday if they secure a loaner for me. I'll update my experience as well when it's done.

Maybe those positive vibes helped out. I've clocked about 900 miles in the week I've had it back with no problems. Occasional longer-than usual cranking before starting, and the alignment still needs to be redone.
I finally filled out the survey I was sent after the first visit, and the service manager emailed me the next day apologizing for how it was handled. I had also separately shared my writings further expanding on what had happened to Porsche customer care, but somewhat surprisingly have heard nothing from them.

The previous owner of mine took it in a few months ago for a cam timing related check engine light. For some reason they had the parts for the recall in the fall, everyone else I have noticed is just getting it done now. Anyways after the repair one of the cams broke and engine locked up while idling in their shop. After that it was an engine out repair to replace the entire top end. I hope it was a one off and this doesn't happen to others (although now my 85,000 mile truck has brand new heads, valves, cams, lifters and all cam drive components).

Do you know if the initial problem with the cam timing CEL was specifically related to the aluminum cam adjuster bolts, or did they just go ahead and replace them too while it was in there getting whatever work was necessary for the CEL initiated problem? Is it also possible someone doing the work in the shop screwed up thereby causing the ultimate failure? In any case, if it was a P dealer, I’d guess it should have been on their dime.

The invoice said that there was no signal from the cam actuator, so they replaced and did the recall. Also mentioned there was some sludge in the head that may have been a contributing factor. After that repair it broke while idling in the shop. Whole thing was on Porsche's dime, not sure if was mechanic's error or something else.
