Anyways, i "solved" the problem by selling the car and getting a 6MT A3 ;-) Dealership replaced the TCU, transmission shifter / switch unit & etc . . . . unwilling to replace tranny.

I never knew what the diff between (A and C) was, however I think it's merely superceding an older part number. For reference I was looking into this in mid 2003 so there are possibly new PNs and etc.

I'd def check with your dealer's ETKA for the latest PNs. Like I mentioned, each one of those solenoids are ridiculously expensive and I'd probably go with VR_Life's advice and source out another tip tranny.

Well I would source another valvebody but I dont want more used stuff who knows how many miles the solenoids had on them. In my situation I am better of just getting new ones. An observation:
Seems that pressure regulating valve the "QTY (1) The one that handles all gears" uses the same PN as the other valves so there are actually 4 01V927333's

Output Diagnostic Test Mode (DTM) (Function 03)

NOTE:
There are two different transmissions:

*~*~*~We have the E17 Transmission!*~*~*~*

Transmission with hydraulic controls -E17-, on which the transmission input speed sensor (inductive sensor) is secured to the underside of the valve body.
Transmission with hydraulic regulation - E18/2-, on which the transmission input speed sensor (camshaft position sensor) is secured behind the valve body at the transmission housing.
Output Diagnostic Test Mode (DTM) (Scan Tool Function 03), Transmissions With Hydraulic Regulation -E17-

NOTE:


The Output Diagnostic Test Mode (DTM) can only be performed when the ignition is switched off, the selector lever is in position "P", the engine is not running, and the vehicle is stationary.
DTM will be terminated when the engine is started.
The function of solenoid valves 1 -N88-, 2- N89-, 3 -N90- and the solenoids for the selector lever lock are checked acoustically during the DTM. Avoid noise in the surrounding area during the acoustic check, because the switching noise (clicking) of the actuators is very quiet.
The solenoid valves 4 -N91-, 5 -N92-, 6 -N93- and 7 -N94- are activated during the DTM. A direct functional check of these valves is not possible. But possible electrical faults which occur during the activation, will be recognized by the On Board Diagnostic (OBD) and stored in the DTC memory.
When performing the Output Diagnostic Test Mode (DTM), the individual actuators will be activated until the -> button is pressed.
Only one complete DTM is possible after switching the ignition on. To repeat DTM, the ignition must be switched off and on again.
Activation sequence


Solenoid Valve 1 -N88-
Solenoid Valve 2 -N89-
Solenoid Valve 3 -N90-
Shift Lock solenoid -N110-
Solenoid Valve 4 -N91-
Solenoid Valve 5 -N92-
Solenoid Valve 6 -N93-
Solenoid Valve 7 -N94-

dealer told me they wouldnt even sell them separately. It was all or none.

He musta saw you were a big baller L10 guy :P

I am going to swap around the pressure controller solenoids this weekend *hopefully* see if the problem goes to another gear. Then if that doesn't solve it try swapping around the shift solenoids see if that fixes it. If THAT doesn't fix it try ordering the master pressure solenoid which BTW IS NOT THE SAME PRESSURE SOLENOID as the rest. I called <a href="http://www.peterschmid.com/">Peterschmid&gt;</a> to verify. The entire rebuild kit which includes shift solenoids, pressure solenoids is about ~900.00 or each pressure solenoid is $204.00 each
