This time it was completely different. I cleared the P0021 and it came back again. I got an oil change in hopes the problem was simply dirty oil...but, of course, not the case. I drove it for about 20 miles and the code came back.
Next will be the cam angle sensors...and hopefully that will address the issue...but if not, grrrrrrrrrrrr.
My car is a 2007 and I just hit 21,000 miles. I am out of warranty. I wonder if it is even worth it taking it to the dealer about this issue...
Thanks for the feedback.

As stated in previous posts, the sensors and actuators were swapped from one side to the other. During this process, we cleaned both of them pretty good and re-installed. I am happy to inform that the problem has not come back. At least, not that silly code.
I have had to deal with another issue. I believe the tune from EVOMS is slightly rich and about once a month or so I would get a "running too rich" on both banks. I would check the code and reset it. During the last 30-45 days, I have been getting "random misfires" and it would manifest in the car running rough and missing on cylinders 1/2/3.
I have put about 2,000 miles in the last 2 months as I did the Crescent Event in Arkansas (what a hoot by the way). I went through a set of tires, brakes and rotors so you can get an idea of how fun it was.
The problem with with the "random misfires" was happening more often and we attributed to the spark plugs as those things have been there for about 10,000 miles now, and considering the car runs slightly rich, then it could make sense.
The plugs looked fouled so I am hoping that was the case. This past weekend, plugs, brakes, rotors and fluid were replaced and after some 30 miles, all seems to be ok now. Tires will be in tomorrow and hope the car is good for a while.
So in conclusion, if you are getting the cell P0021, you might want to clean your sensors first. I am not saying that is going to fix the problem, but, it could.
Agreed, this happened to me last month. Swapped the sensors and the issue hasn't come back. I still have to drive the car more and this winter isn't helping. So I don't know if it's going to return. Fact is if the sensors are swapped and cleaned, then it was just a dirty sensor. If the new sensor on the same bank that the issue came from rises from the dead... you're in for a big bill. Please god let it be a dirty sensor...

Good luck man, let me know what the shop quotes you, curious what an indy shop charges.

Did you swap the sensors yourself or did you have a shop do it?

I just swapped mine, and if you want to try it, you can get to them by following my Spark Plug DIY tutorial. I did it last weekend and maybe took an hour or so. You do not even need to lower the engine to get to them.
Good luck...

i read this threar and didt saw any pressure problems with anybody.
so what i have?i have cel p2100
how i detected it.one drag weekend after 1st qualification i wanted the second run
that i pressed together brake and accel pedal and my car didnt get any boost more that 0.2bar.before it was without problems 0.6-0.8bar.when iam back i have read fault codes and found that code((pity
before 4000rpm car runs looks like school bus acceleration and after that it runs normal .
also with turbo pressure when car just started and cold it gives me 0.6-0.8 bar.after car becomes hot(normal work temp) it will not give any pressure i want((
so what i want ?change oil, sensors (FROM SIDE TO SIDE) and actuators and may be wwill see some sleeves may be they are dirty.
who can explain what does it means taht pinning?What is that?anybody may be can give some pics before and after?thanks

Reason: add info
Have there been any updates to this issue? Is there a way now that we have Accessport logging to see if the issue is just a bad sensor or a spun cam? I am probably 125 miles in after a fresh oil change at the dealer and CEL on drive home....slow 15mph stop and go traffic when it popped.
編輯：這絕對不是由改裝引起的 - 有一個壓入式套筒，從工廠沒有正確安裝。這可能甚至不是保時捷的缺點 - 無論他們從哪個品牌購買這些攝像機都會被責備。2009年的奇怪的是沒有這個問題，所以在凸輪的當前修訂中 似乎已經解決了問題。如果一個經銷商試圖否認索賠因修改我把它帶到另一個經銷商，永不再做些生 意。[/ QUOTE]
Hello, I have a 997TT from the United States in 2007 in Taiwan.
The number of inspections is 46800km.
The current check engine light is on. Can't eliminate the error.
The fault code is p0021
Does your friends have the same situation?
How to solve this problem?
Can you share, thank you.
Thank you, after reading all the articles, I am very worried that my 997TT is due to the rotation of the camshaft. I have already contacted the Porsche technicians in Taiwan. I hope my car can be successful again.

Before going straight to the big ticket items of changing out cams...try the actuators first.
Thank you for your suggestion
Porsche technicians have already
aligned the solenoid valve and the
camshaft sensor before checking the camshaft.I get the same result. I will ask the technician to test the actuator again.
