17705 and poor fuel economy.

Morning,

Is there a list anywhere of what measuring block 'group' values actually are? My car (mk1 octy 4x4, SAI, 249 & 112 deleted) has poor economy!! driving miss daisy sees me get about 22-25mpg.

I have basic VAGCOM and am getting the infamous above fault code suggesting looking at DV but i have a new (2-3 months) turbosmart recirc valve fitted. In group 26 (i think) of the measuring blocks there are 4 voltages (between 0.5 & 0.7 ish volts @ tickover and rising with revs. 2nd block along in this group rises much faster/higher than the other 3... is this normal??

Are there seperate readings (blocks) for the CTS for gauge and ecu? (several blocks just say 'temp'

TIA,

Jason.
