sooooo, after a whopping 1.5wks and a few tanks of fuel in my new to me '07 S6 - it threw a CEL. Fak! Figured was only a matter of time honestly, seems to be my luck!
odd part is, I sheepishly admit I’ve no clue ‘when’ it came on - my steering wheel rim completely blocks that upper quadrant of my cluster… d’oh
pulled the code, and got this: p1085-004 bank 4 mixture regulation lean limit exceeded
did a search here, didn’t find it
Googling reveals a slew of ugly issues that could be related to this - but ALL of those posts on forums were accompanied by a glut of “other” codes in conjunction… mine’s just this one
cleared it, came back on about 70-75mi later… this time I saw it, came on during a 15-20mi period of light throttle 50mph cruising in 6th gear
can anyone please share any insight they might have to point me in the right direction here?
thanks much in advance!
