cascadia regen..... nightmare!

Sorry to hear it, man. I lost a turbo leaving that Love's back in August and spent a weekend in Lexington waiting to get a new one. Lexington is actually a pretty nice little college town, so I guess it could be worse.

 

Your filter is full already. By the time that the lights come on and the stop engine light comes on it is too late to do anything about other than take it to a shop. No point in messing around with it. Two things on the aftertreatment system will cause this. To high of a temp or to big of a difference in pressure between the front of the filter and the back of the filter. The dozer or doser vavle is the valve on the exhuast pipe right after you turbo. It should have at least 3 lines going to it. Coolant in, coolant out, fuel in, and one connecter. All this valve does is put raw fuel directly into your exhaust stream. Sorry to hear about your luck with this issue. Hope everything gets worked out this time.

 

Man that sux.

When mine went bad I tried freightliner davenport. Told me all I needed was a regen.
Then freightliner cheyenne, replaced a sensor, fixed it for a while.

Then went to smiths Detroit here in slc, replaced the dozer valve and 50,000 miles later she's still good.

At least someone knew how to fix it.

 

I drove a 2008 Cascadia for about 6 months. Mine had the 60 Series Detroit. Never had a problem with the Regen working correctly. I know for a fact that if you monkey with the HP/Torque it can affect the regen system. The comapny I was working for at the time dropped their top speed from 68 to 65. They had to leave the Freight shakers at 68 for a little longer due to getting the right programming for the Detroit. Also, sometimes I would see over 7.0 MPG pulling heavy loads, and then have days where I could barely get 5.5 MPG pulling nearly empty trailers. the wonders of modern technology...

Also, when doing a parked regen, let the truck slow the idle down on its own when the regen is done. Wait for the throttle to come back down completely and be sure the High exhaust temp light (HEST) is out. Don't monkey with cruise, throttle, regen switch, drive or shut the truck off till this happens. If you try do drive or mess with it without letting the computer do this on its own, it may trigger warning lights again after a short distance, thinking the cycle never completed. This is the problem I was having with the Cummins ISX.

I've driven Caterpillar, Cummis, and the New International Maxxforce 13 with regen. All of the new engines have their little quirks. Most of them make a backfiring noise when shifting gears. None of the new engines are fond of stop and go traffic. It can clog your DPF in a hurry. Also, surging and rough idle (such as going across a parking lot and your RPM's won't stay steady with your foot). And the smell while doing a regen is putrid, coming from the hood not the exhaust. I will say the Maxxforce was the worst, I couldn't even put my windows down when the thing was doing regen on the highway.

Both the Detroit ans the Maxxforce I noticed soot around hoses and metal fittings where the high temps where causing leaking. Who cares if the driver inhales it, as long as the exhaust pipe is clean, right? I always found it a bit redundant to have something designed for pollution control and then have to do a regen at 1400 to 1700 RPMs for up to an hour and a half every few weeks. All in the name of clean air.

 

Also, not to be insulting, but is it posible that you or one of the previous drivers put Low Sulfur Diesel (LSD) instead of Ultra-Low Sulfur Diesel (ULSD) If you fill one of these new trucks with the old fuel you will cause mega mega dollars worth of damage.

I had a situation a couple years ago where I was in Georgia low on fuel, and there was a shortage after a hurricane and nobody close to me had ULSD. My company told me stick in 50 gallons of the Low Sulfur fuel and get it back up north and then fill with ULSD ASAP. It worked, but I think the truck was doing constant regen going down the road. Truck ran better gradually after a few ULSD fillups. I'm sure Detroit would void the warranty if they got wind of it...

 

replace filter at 300,000? really? I have a series 60 cascadia and that hasnt been done, but it does have a "turbo speed low" code on all the time and a "radar network" code on all the time...
