I have my 2011 duramax, 60K miles in the second time in a month for the cleaning exhaust filter message coming on and not going out. First time they said it needed a manual regen. Cost me $300. Don't know this time yet. Anyone else have this problem? What did you have to have done? Anyone have the DEF and the exhaust filter removed and a different tuner put on? If so what did you get and how has it worked. Any other thoughts?Thanks.

Do you do alot of idling?? Alot of stop and go with no highway driving?? If the engine never comes up to operating temp, stays there for awhile, and operatered at highway speeds, it cannot/will not go into regen.

I've found that cold weather causes me problems. The exhaust temps just do not get up high enough to do the regen. I had to take it to the dealer for the regen one time. Luckily it was still under warranty and didn't cost me anything. It really shouldn't cost that much for a tech to plug in the laptop and park the truck in the lot to do the regen. It is not like he is sitting there watching the truck run for 3 hours.

$300 to punch a few buttons? I spent my whole life in the wrong business.

I always thought Federal emissions warrantee was good to 80k/8 on any vehicle in the US?I haven't checked on it in forever. Was that changed?

Get a code reader and see. When my F259 goes into cleaning it take about 20 minutes on the highway to stop.
