Durametric Diagnostic Question

[Porsche Enthusiast]

Guys I need some expert help still. I have tried to figure this out on my own but I am not there yet, and precious posts are.

I had a funny "diesel like" rattle when sitting more than 4 hours. Did some reading and read code with a scanner (misc cyl misfires bank 2) and concluded chain tensioner. Then car cel started flashing and car ran like missing a cylinder or 2. Changed out tensioner, no luck.

Broke down and bought Durametric and I get the codes (see attached) during short test. When I check actual available values, I get no Camshaft Position Bank 2 deviation reading. Nothing at all. I found the tech article on sensors, checked them out and they all apear to be connected just fine..

Yet I get a P1524 (Cam shaft adjusment bank 2 error. I have checked the sensors and assuming I know left and right, the position senors are all connected. What sensor is responsible for dev bank 2 reading?

TMM-- Thanks that was what I was afraid of. I was hoping it might be a sensor or a wire issue. So is this a definate or is there anything I need to rule out first?

I finally bought a low profile hi lift jack today, Am I understanding correctly I need to drop the engine if this "bank 2"vario has gone kaput?

Anyone else please chime in with a second opinion/option, please!

Back in the day I could drop a VW bus engine in 12 minutes flat, somehow I am thinking this will not be so simple, I am sure...

In the image you have, it does not appear that you have "selected" the cam deviation values (note the checks in the boxes below). The Durametric software is very capable, but takes some getting used to......

JFP, I was looking for you...
No we checked cam 1 Deviation, worked fine...

Look close there is NO Cam Deviation 2 listed... Thats my problem... Doesn't make sense unless the actuaor is electronically "dead"?

The actuator is not the source of the signal. The cam position sensors tell the DME where the cams are in realation to the output of the crank sensor. I'm not sure why the Durametric does not see the other sensor, but it could be fried or disconnected.

Each cylinder head has one, item #34 in the attached:



Shown here is the camshaft position sensor. There is one located on the top of the left cylinder head towards the front, and one on the right cylinder head towards the rear for the 5-chain motors used up to about 2001. For 2002 and later 3-chain motors, the sensor is located on the top of the left cylinder head towards the rear, and on the right cylinder head towards the front.

Sorry to not be posting something contributing to the resolution, but I have to ask just for my own understanding...are you saying that the car was idling for 4 hours?
