DSG - For those who have dealt with N215 - short to plus code

Has anyone had luck with simply changing out the N215 solenoid valve in the mechatronic with the tranny still in the car? I assume that you can't assume that the solenoid valve would be the only thing that could be what causes this, i.e. anything else in that circuit that would cause a short.
I'm trying to find the path of least cost and labor before committing to replacing the entire mechatronic.

18223 - Pressure Control Valve 1 (N215)
P1815 - 008 - Short to Plus - Intermittent - MIL ON
Freeze Frame:
Fault Status: 10101000
Fault Priority: 0
Fault Frequency: 255
Reset counter: 40
Mileage: 385270 km
Time Indication: 0


There is another fault code in the TCM for this:


00194 - Ignition Key Removal Lock
008 - Implausible Signal - Intermittent

I went looking for the key lock solenoid and it is not in the ignition lock anymore. It must have been giving a previous owner some grief.
I don't think that these two would cross paths but don't have a wiring diagram for DSG (thanks Bentley!)

A bit more added info...

The car came in without the code and it did not trigger after numerous test drives. I first noticed this code after performing a basic setting procedure on the transmission. I have found a few very similar incidents here on the forums.

The owner never mentioned that there were issues with the trans but was not totally surprised when I mentioned that a problem cropped up that did not allow reverse to engage once the car warmed up a bit.

Well,
Swapping out the N215 did not help. I guess it is time to break the news to the owner about coughing up cash for a new mechatronic.

A new mechatronic unit corrected the problem.

.... almost six years later?

Some people cough up cash slower than others.

He was saving up money.
