There isn't any selective output tests, whether the TCU allows a sequential output test I've not looked.
When testing with VCDS measuring blocks to note are these:
MVB 5
Display zone 1: Solenoid valve 1 -N88
Reverse/first/second/third gear: off
Fourth/fifth/sixth gear: on
Display zone 2: Activation pressure regulating valve 1 -N215
(for clutch A)
Display range: 0 to ... mA
Display zone 3: Activation pressure regulating valve 2 -N216
(for clutch B)
Display range: 0 to ... mA
MVB6
Display zone 1: Activation pressure regulating valve 3 -N217
(for brake C)
Display range: 0 to ... mA
Display zone 2: Activation pressure regulating valve 4 -N218
(for brake D/clutch E)
Display range: 0 to ... mA
Display zone 3: Activation pressure regulating valve 5 -N233
(for ATF system pressure)
ATF: Gear oil
Display range: 0 to ... mA
Display zone 4: Activation pressure control valve 6 -N371
(for converter clutch)
Display range: 0 to ... mA
MVB 7
Display zone 3: Torque converter clutch status
Converter clutch open: TCC open
Converter clutch regulating/slipping: TCC control
Converter clutch closed: TCC closed
Fingers crossed for you mate.
