Need some assistance checking my N75 valve- how to check in VAG-COM?
I can not seem to get out of limp mode- car won't boost over 6psi.
What I have done already:
Reset battery
Reset throttle body
unplugged MAF and drove around
Disconnected Boost Machine
Checked hoses coming and going to the N75 valve
Here are my codes as reported yesterday, and what I have found so far...
Throwing 2 codes:
P0106- Mainifold/Barometrix Pressure Sensor (G71)/(F96): Implausible
P0238- Manifold Pressure/Boost Sensor (G31): Signal too High
After looking up both errors in the Bentley I found they both point to the N75 as the failure point- unless it is the actuator rod connected to the turbo.
I know there is a way to check that the car is communicating to the N75 valve, just wondering how people have tested that? That at least will start me down the path of a bad N75 or bad wiring harness. Thoughts?

I ran some logging with the VAG-COM on Blocks- 115 and 032
<center><img src="http://pictureposter.audiworld.com/11040/groups_115_032.jpg"></center><p>After reading a BUNCH of threads about N75 issues, and others I tried to take that and make some logs myself. Tell me if anyone sees anything specific here- or if I should be logging something else?
