I think I've read through most of the REGEN/DPF posts and haven't seen a question/answer on this (course I may just not have been reading closely enough). When does the Exhaust Filter Drive Complete message appear - is it meant to appear everytime after a successful Cleaning Exhaust Filter process? I'm asking as I was driving this evening, the CEF message appeared so I figured what the heck...I like to drive and was close to the highway...was out on the highway for about 20 minutes @ 80km/hr+ and the message eventually disappeared but no Exhaust Filter Drive Complete message ever appeared. Did my cycle complete? I'm wondering if the EFDC message only appears after a Drive to Clean Exhaust Filter occurence. Thanks in advance for responses.
