ESP and Standing time

Hi,

I want install ESP (Passat/Audi A6 platform) in my car but I not have CAN dashboard, this ESP requires standing time information from dashboard over CAN (old ASR have this signal on separate wire), can anyone help me find on what address and format is this information on CAN ? I catch data what send CAN dashboard board from Passat B5 but I cannot find where is this data, this is snippet what dashboard transmitting to motor CAN:
320 8 12 00 FF 00 00 00 00 00 249
420 8 87 FF FF FF 40 00 FF 00 2002
520 8 15 C0 00 83 80 ED 54 01 1997
5d0 6 80 34 50 80 18 41 999
5d8 8 15 04 00 3E 11 00 00 01 999

(I have in plan made CAN dashboard emulator and information about what others data represent it will be helpfull also )

thanks for any help or hint :)

nobody ? I bit experiment and watch that data and only this is changed:
520 15 C0 00 83 80 ED 54 0
4th byte (83) is incremented and actual value is sent only at IGN powerup, when is IGN on, value is not changed, new value is sent only after IGN off (some waiting) and IGN on, increment depend on time when IGN is off but I cannot find any relation between time and this value...
5th byte (80) is also incremented () but only when 4th byte reach FF and start from 00 again.
nobody not know what data is on address 520 or this forum is dead ?
