Hello all
Having cleared the codes with my iCarsoft Pro, a fair way thru another ghastly stop-start commute journey on a not-too-warm day (outside temp ± 25c) warning light comes back on.
CR Pro says"Selfadaptation of mixture formation, The mixture is too rich in the part load range, [P0172]" which is the same as last time.
The error codes list tells me "System too Rich" which is not as specific as the message from the iCarsoft. (I mention the very slow traffic conditions under which the light came on just in case it has any bearing, possible on the way the cat was working?).
Is this something to worry about? and if so where should I look first. My guess is O2 sensors. Of which i believe there are two either side of the Cat. Can my iCarsoft CR Pro receive the readings from the lambda's when the engine is running, as shown in some youtube vids?
Thanks
