Have a little problem with my vcds.
Recently bought an A4 B6 1.9 TDI,connected up my vcds and everything worked.
However,as the fuel gauge in the cluster didn't work so bought a second hand cluster and swapped over the fuel and temperature gauge.
Now everything works in the cluster,but i can no longer connect to the instruments or even do an autoscan (can search for fault codes in everything individually except instruments though),could do both before the cluster repair.
Any ideas of where i've screwed up ?
