hello all

got a w210 E240 avantgarde x reg. car engine seems to be hunting a bit when stuck in traffic or traveling at low speed. plug it into a diagnostic machine and it came up with the following
air pump swover valve R cyls off
air pump swover valve L cyls yes

P2017 Self adaption of mixture formation for right bank of cylinder is at limit valve (at idle speed) E
P2016 same as a above but in brackets (right at part load) EN
p2086 self adaption of mixture formation for left bank of cylinder is at limit valve (at idle speed) E
p2085 Same as a above in bracket (left part load) EN

any ideas what this mean exactly. not sure but has a look and could hear air noise coming from ns of engine .
:)

im not sure, and ive been out tonight, but im sure ive seen self adaptation fault codes somewhere on here before recently and im as sure as i can be that its a MAF fault. im sure someone will correct me if im wrong!

S-A-M/U-N-I-T will know much more than me, as will hertfordshire merx and many others whose names i cant recall at this time im afraid!!
