This could very well be an M5-specific code>>
The M5 is not covered in the Bentley manual.
My guess is that there is an intermittent connection somewhere in the pre-cat sensor circuitry.

Good to hear you're finaly getting some rain...
We're getting more than our share in Northern California to date but understand that this is a La Nina year and we probably won't have sufficient from now to April.
Merry Christmas and Happy New Year!
Re: This could very well be an M5-specific code>>
edjack THANKS ! :) I had wondered about the limitations of my Bentley Manual but couldn't find another manual available for the S62 engine. Thanks for your thoughts though it would appear that something is going on with the O2 sensors......I may just have to take out a loan and go visit my local stealer ( who is an hour and a half's drive away as i live rural ). All the best to you and your Family for the Christmas season and the New year ! :D.........KennyGhttp://forums1.roadfly.com/preferenc...php?img=135692
