Title: 18258/P1850 - Powertrain Data Bus: Missing Message from ECU 2.7 swap b6 a4 Post by: Focal on May 17, 2014, 08:15:17 PM 2002 a4 2.7t car runs very smooth but trying to get rid of this error scanned on the "ABS/ESP channel 18258/P1850 - Powertrain Data Bus: Missing Message from ECU " i have a feeling this has to do with a wire on the RED b5 s4 plug a green/brown wire that traces to pin 74 on b5 s4 ECU i think i read something once that said that should go to j104 (abs module) i was wondering what you guys think
