Not sure how to post pics but I`ve broken it already. 
In fact the emissions control light (engine block picture) came on as I was leaving the dealer`s on Fri, they read the code (02 sensor) and re-set it but couldn`t change it out as they didn`t have any. :thumbsdown: Anyway it`s back on now permanently, the car`s running perfectly smooth and not going into "Limp" mode so I`m guessing it`s a Post-cat sensor rather than pre-cat and need to get it booked in at my local dealer.
It seems the 02`s are a common problem on the E85/6 M, why is this ? My last E46 M3 had no problems with them in 3 yrs of ownership and 2 of those years were supercharged.
