2010 Carrera S 6M Cab 150k miles

TLDR: Dealer tells me the code is 2402 and Durametric returns 0024 with a description that matches the dealer.
I am getting screwey values when I look up actual values.
I try to clear codes and they don't seem to clear.
Has anyone else seen this?

I got CEL after about 1000 miles after replacing the catalytic converters myself. I pulled the codes with my Durametric and got:
0024 - DMTL Diagnosis module for tank leakage; pump drive rUpper limit exceeded
0010 - Intake camshaft driver

I took it to Porsche because I wrongly figured this was related to my cats. They pulled the codes and said the car was throwing 2402 and that the 0010 was in the system but had been there for a long time and was not relevant.

Now I had cleared that 0010 about a half dozen times so I thought it was fresh. It did not register at the time, but that means my reset did not work.

They said that it would cost $1,100 to replace the DM-TL and filter. It was very likely the right thing to do because they tried to actuate it and it would not spin.

As I have dropped about $14k on my Porsche habit in the last 30 months and my wife has had about enough of this, I paid the diagnostic fee and replace the parts myself (saving about $700).

Now my Durametric is still pulling the same codes plus a new one:
0014 which it says is No signal/communication

That code, like the 0024, is not in my copy of the Porsche 997 essential companion.

So when went to look at live values relevant to the DM-TL the Durametric was putting in some weird results. Percents or bars when the units should have been seconds.

Background: DM-TL is a complicated pump/sensor that determines that there are no leaks in the gas fume recycling system. It pulls low amps if there is a leak, so a high value means there is a problem with the pump or maybe a short.

 

What is the Porsche 997 essential companion? How can I get a copy for the 997.2?

 

here ya go!
