CIS-E3 problems - temperature sensor?

[L DC]

Not to highjack Eyvind's thread but this goes along the lines.

John, as in Eyvind's case, and as per the suggestion of a QSW Syncronized lister (http://autos.groups.yahoo.com/group/syncronized/), I have also done that quick test of unplugging and plugging O2 sensor on my VW QSW (JT code) to determine its effectiveness.

No difference what-so-ever.

Could you elaborate on that if you would please?
