I just wanted to post a followup to this problem. I found a lot of threads with this issue and many times there was no closure!
I went to the Indy first - they scanned with PIWIS and confirmed the bank 1 code p0011. They swapped the camshaft position sensors and the CEL stayed on the same side. My next step was to change the part number listed above which is part 26 in the diagram shown a few posts ago.
So I order the part and decide to take the car to the Porsche dealership b/c the Indy shop just doesn't instill confidence - they didn't properly connect the intercooler hose on the passenger side - big boost leak. Pretty much every time I go to this Indy there is an issue. I figured what the heck I'd go to the dealer for once. They scanned the car and found other codes with PIWIS that the Indy didn't find, or mention. The tech advised that I ordered the wrong part. Rock, that part you listed (starting with 996) is the solenoid for the valve lift, which apparently is nothing to do with this fault code. They replaced the solenoid for vvt which is part number 22 in the diagram. (the part 26 is the valve lift solenoid). I was charged for 6 hours labour which is painful at the dealer rate of $155 per hour PLUS TAX, lol. The crappy part was that I had assumed he had to take off the bumper to fix my issue but he didn't. So I had to pay another hour labour to re and re the bumper and reconnect the boost hose the other shop didn't connect properly (the Indy would have fixed it for free). Oh well, lesson learned. When the tech was advising that I had ordered the wrong part in a subtle "don't diagnose via the internet" voice I couldn't help think of the irony here as I use that voice all the time when people come to my office after diagnosing themselves online, lol.
I had a few other minor things done and next thing you know the bill for parts and labour is 2 grand. That's Canadian, and right now that's cheap in US dollars but it hurts nonetheless. There is no CEL and the tech says the car drives great and very powerful. However, he can't clear the p0011 and says that there is no signal to the DME from the bank 1 camshaft position sensor. He says it's not a problem to drive the car because the car will use the signal from the opposite sensor. After I thought about it I realized that doesn't make sense because my datalogs show that there is a signal for "actual camshaft position" for both banks. Oh well, I'll pick up the car tomorrow and wait and see what happens. Apparently by changing the part mentioned the timing issue is resolved. I will post a followup....
Sorry about that part # issue. Typically that is what we/they change first as it is not that expensive and easier to get to ( it is in many posts, and listed as Variocam Actuator Solenoid)...But I am also aware of the other part. Too bad they cannot turn off the CEL??
No worries Rock. When I was looking at the engine schematic I noticed a number of different solenoids etc... I was lucky they didn't charge me a restocking fee for ordering the wrong part, but then again it would have been a drop in the bucket compared to the total bill, lol. I wish the tech had written down the other error codes that were stored in the memory, and which led him to the diagnosis. I don't recall any other codes under the same category when I scanned with Durametric and Cobb AP.
I will pick it up this afternoon. I'm still a little nervous about the p0011 they can't clear but the CEL is not on (yet!). I guess as long as the camshafts move in sync it's not an issue. I can always look into the wiring as a possible cause next time I get my plugs changed.
I would be adamant about service manager not being able to clear that CEL. You are paying dealer pricing it should be perfect.

Tech says it's because one of the camshaft position sensors isn't sending any signal to the ecu. Not sure that makes sense because my datalogs show something on each bank.
Anyway, the car has no CEL. The Cobb AP doesn't pick up any error codes. And most importantly the car runs great, like it used to. Over time I had felt that something wasn't right and I was right! The idle is much better now, the smooth power between 2 and 4k rpm is back, and the rush of acceleration has returned. The datalogs show that there are no weird timing spikes (that would trigger a CEL like the p0011) so it looks like all is well here. I'm not sure what PIWIS was picking up that neither Cobb nor Durametric can. Time will tell I guess.
Technically I didn't pay the P dealer to "troubleshoot". I went in there and told them to change the solenoid - and it turns out I had asked them to change the wrong solenoid, lol. So if they had done what I asked I would still have a CEL and drivability issues. So I am thankful that they sorted it out. Obviously if the CEL comes back I will have to look into it further...but in the meantime I'm loving it.
Hi there....I had a question if you have a second. Was that log done with durametric or AP?
Is the parameter literally called camshaft position?

I just changed the oil today and will reset the cel and see if that helps. The x axis above is time in seconds. I rowed through the gears up to 4th gear in this log.
A couple of years ago when I had the p2100 cel with the bank 2 camshaft the cel came on when I was on my way to the track. I drove the car fairly hard that day and no ill effects as far as I know. Later the camshaft was changed under warranty. But now that I've seen all of the knock sensor activity with the current cel I'm guessing that I shouldn't drive the car until this gets sorted out. I presume the labour to get to the actuator is the pricey part so I may just buy an actuator and have the bank 1 actuator replaced. If that doesn't work then I'll have to prepare my wallet for some pain.
