I don't own an MK4 TDI, but this link leads me to believe that some sort of fuel consumption signal does exist. Of course, the cluster pinout provided in that thread does not indicate a fuel consumption signal, but how else would the cluster retrofit be able to calculate fuel economy?

Actually, I just bought an 99 Audi A4. I'll check out the Bentley and see if it may indicate a fuel consumption signal on the ECU schematic. Mine has factory MFA. I imagine it would be very similar to the VW setup.
