Engine fine on warmup,nice lambda switching, then once up to temp O2 sticks at .84v but responds instantly to throttle movement. Using Vag com, no DTCs but on Measuring group '2' there is a voltage displayed which when at nbv all is well but then changes to a varying voltage of 2-16v when running badly. I need to know to what this voltage refers to. Also CAPs info only shows the earlier vane type AFS (not internal MAP sens) or the usual EOBD cop-out so pin-out data would be appreciated. The ECU has been tested by ATP and deemed ok by the way. Sorry to ramble Andrew
