Hi there, i am trying hard to identify a possible dicky thermostat as a cause for high fuel consumption. THere are numerous measuring blocks within VCDS which measure "Temperature".
I know that the reading for the dash guage and the ecu are taken in different places. Anyone know specifically where the ECU takes its temp from and how i can read this in VCDS to check against dash guage.
My engine is the AVF in an A4 1.9 TDI
If it helps i am using the old 4.9 VAG Com software
