Early emission problems

[baer]

Considering purchasing a Phaeton and wondering about the early Cummins engines that had to meet emission standards.
Looking at the 08-10 models, any good or bad experiences with those particular years or would it be better to be looking at pre emission engines?
Any info is greatly appreciated

Our Chassis is a 2007. We have the 340hp six which has the cat converter but does not yet take DEF. Works like a champ. Been full timing in it for a year, had it for a year and a half. We are careful to avoid excessive idling and use the idle speed bump up when forced to idle. We had never even seen it doing it's cleaning sequence until recently while climbing mountains slowly and wouldn't have known if not for the dash indicator. It has circled the country one full time, climbed the Rockies in Colorado spent days at a time on the interstate and lots of time on 2 lanes in the West without a hiccough. I wouldn't worry.

How many miles? My only concern is for the DPF filter. I would have Cummins update the ECM for the latest versions. Based on the dumpster full of the filters they did have considerable growing pains and passed that pain onto the consumers. Extended warranty companies followed suit and did not cover them.

I suspect it is around 4-5K to have one diagnosed and likely replaced today. Perhaps a good ECM update and a DPF filter cleaning to remove any concerns.

My regenerations have been totally different since they updated my ecm and have had no further problems.

Around those years there was a newer version thermostat that came out. Easy enough to change.

If the RV has say 50K miles on it and a service history I would not worry about much but as always, feed the maintenance budget well. These things eat $100 bills.

Interesting. I did have the ecm updated and that is when I started seeing the regen working. Mine has about 40,000 mi.
