Hope this helps.............

 Hi Ashraf,
Thank you.  I think I am ok with the regen itself... I just cant find the exhaust temperature data... I think I have to find the right channel in the Can-Bus?  I was wondering if anybody knew the channel, if not I will just go through all the channels one at a time.
Thank you.
Regards,
Peter.
