Trickygti 3 Posted April 17, 2013 Report Share Posted April 17, 2013 Going off the VAG measured value blocks rather than vagcom ones engine load should be MVB 3 Zone 2 and should be between 1 & 4%Display group 3 -Basic functions- for control unit number: 021906258A ... CKRead measured value block 3 ⇒ [ltrif ] Indicated on displayxxxx rpm x.xx % xx <° xxx.x °C1 2 3 4 [ltrif ] Display zones Specification Evaluation Intake air temperature -45...108.5 °C Throttle valve angle 9...19 <° --- Engine load 1.0...4.0 % --- Engine speed (idling speed) 650...750 rpm Hope that makes a bit of sense, was everything switched off i.e lights, heater, and any other electrical consumers?
