Audi A6 '98 - Tiptronic Problem

[Azzx]

Hey

I have a problem with Tiptronic on 2.5 TDI Audi A6, 98 year.

I have the DTC P0706 (according F125 switch) - on dash all gears ligten up.

Changed switch - the same DTC.
Disconnected switch - the same DTC.
Checked the wiring (8 cables, 4 goes straight to TCM - all ok, 5- ground - ok, 6-reverse lights - ok, the two left goes somewhere else but they are okey near TCM).

Any ideas (have anyone where the two left cables go?, blue with black strip, brown with white strip)?

The TCM is under passenger carpet (don't have atm any other TCM for change).

Thanks

I have changed the F125 switch without success (I posted it above).

Hi,
dear i thing b/w is for start system, and b/w is ignition, did you check is on the f125 have ignition after open ignition?

[Azzx]

You posted twice b/w, you mean ignition by b/b - black blue?

I figured that there is 12V on Black/Blue by some manual (haven't checked yet).

On the Brown-White is also 12V?

From manual:
1+6 with ignition on - 12V, 1 is black-blue, 6 is brown - ground

So what the brown-white stands for (number 7)?

Thanks!

The brown-white goes to "V94 - Central Locking / Alarm System / Interior Light Delay Control Modul"

The module is under driver carpet (LHD), so looks like there is problem with TCM - wiring OK, F125 OK.
