So for those that don't have warranty for whatever reason. I say we should figure this out. Ive been reading for several days anything I could find on the DSG Mechatronic unit. I've seen a few change their units themselves and one brave guy also will try to disassemble the unit to see what could possibly be wrong.
I say maybe some good techs,transmission specialist, eletronic specialist etc. could shed some light on this issue.
In most cases we know that the TCM throws code: 18227 - Pressure Control Valve 2 (N216): Open or Short to Ground P1819 - 008 - Implausible Signal - Intermittent.
By very simple deduction, there is a problem with power going to this valve.
As you can see on page 30 of this document:

There is a circuit board ( identified as *B* on the picture). Maybe the solder or somehow a crack in the board would explain the issue.
IMPORTANT: I will test with vagcom again, but 2 days ago I could read Volts and Amps values of Solenoids #1 and 2 using Vagcom in TCM.
When the codes are cleared both solenoids show Volts and Amp values normally stable. If you shift to D and wait 10 secs you will get the PRNDS flash of death and you can clearly see the value of Amp. of Solenoid #2 drop to 0.00Amp.
Which makes me think, why is there power at first and then the it is cutt to throw code Open or short to ground?
I will try this week to take out the mechatronics unit and see if there is any sign of dammage or somehow try to understand the issue.
As of my understanding...
18227 - Pressure Control Valve 2 (N216): Open or Short to Ground P1819 - 008 - Implausible Signal - Intermittent.
Means that when the TCM tests or uses Valve N216 it either malfunctions ( doesn't open/close or is simply stuck). The TCM reacts by cutting power to it and throwing a code.
Does anybody know if this code really is an electronic fault or could be mechanical?
