Hi

I had to change cluster to my Audi A4 B5 -01 because old MagnetiMarelli cluster start to turn off and on during cold weathers.
Old is MagnetiMarelli 8D0920900T and the one i put in is 8D0920930C (From -99 S4).

That S4 was with IMMO2 but it was quite easy turn it to work with IMMO3 by VCDS.

Now the cluster work fine and most of those extra features also (FIS). Just couldn get the aux. heater control work (cant get cluster sent any signal to that pin).

Now the biggest problem:
Cant get ME7Logger connect anymore.
Nefmoto -program works fine.

I have tried change .ecu file connection options, even to 0x00 (KWP1281) ans speeds.
Allways get cause=0x04

If i remove K-line from cluster after start then any software cant connect anywhere (VCDS, nefmoto etc...)
