Also ran a shareware version of VAGcom and got fault codes 00561 - Mixture Adjustment Control, 16486 - MAF Low Input, 16502 - ECT Sensor G62 Signal Too High and 18010 - Power Supply Terminal 30 Voltage Too Low. I replaced the MAF last Wed and the battery was disconnected so that probably accounts for 16486 & 18010. Am currently sourcing a G62 (16502) so that just leaves 00561. Any thoughts would be appreciated
