My 2007 S8 (101k) has been throwing a cell lately, I cleared it at first hoping for the best but its back. VCDS scan shows:
000048 - Oxygen (Lambda) Sensor B1 S1: Heating Circuit
P0030 - 004 - Malfunction / Open Circuit - Intermittent - MIL ON
Freeze Frame:
Fault Status: 10100100
Fault Priority: 0
Fault Frequency: 5
Reset counter: 255
Mileage: 163965 km
Time Indication: 0
Date: 2018.03.15
Time: 13:35:45
I searched and cannot find anything specific to the S8, There were some A8 comments around cleaning the connections that seems to address the issue.
Anyone had this on an S8 and fixed it, please god don’t say its an engine out job
