pullz 5th wheel II Posted January 7, 2008 Share Posted January 7, 2008 I was a little shocked to see smoke for the first time from my '08. I had about 13,000 miles on it. About 4 miles into my 16 mile hwy commute it felt like it went to regen and I noticed blue smoke as I pulled two short hills, smoke only on the up hill. Second time coming back from Wisconsin at 75mph, around 375 miles into the day I was on a flat stretch and shortly after it started doing its thing I blew some blue ( or what appeared to be) from the pipe. It was close to a fogger for a few seconds. Has anyone seen this? Can someone explain the sequence of operation when regen is required.

MTSuperCrew Posted January 7, 2008 Share Posted January 7, 2008 (edited) My Dad's '08 has been doing that for about 6 months now. He had been working with a couple different dealerships about the problem and they didn't have a clue what was going on so he checked out another local dealership and they said it needs a software update and one of the sensors in the DPF needs replacing, supposedly it is out of spec.

MTSuperCrew Posted January 21, 2008 Share Posted January 21, 2008 My Dad had a sensor in the DPF changed and a software update to the computer and now no more smoke screen plus his mileage has went up. Quote Link to comment Share on other sites More sharing options...
