i created a basefile for a TT with S3 MAF and 550 Bosch EV14
rear O2 is removed
Is there a reason it is open loop and not reaching lambda 1 at idle?
current dtcs:
17834 N80 TANK VENT VALVE
17841 J299 SAI pump relay
17840 N112 SAI RELAY
17695 N249 SUV VALVE
Until you disable powerstage diagnosis you will not get trims or lambda regulation.
