How often is Regenerating on 2007-2008 trucks with a c13

The cat system sucks plain as that.... If a cat is constantly asking for a manual regen it means their are problems. And not doing the manual regen isn't an option so you've got to do it.......most regen every 200-300 miles.

There's been like 1000 updates on the art head not that it helps.......

 

Once my former '08 Cat sdp was fixed right by the Cat house, it would go 2-3 months without a stationery regen.
of course with time all sensors and regen parts get stuffed oF soot and then you'll go back to the Cat house

 

Mine won't do manual regen unless light is on requesting it! rarely ever do manual regen, but change ard head about every 12 months, its junk

 

Ya mine will not let you do a manual regen unless the ECM tells you to. You can push the button all day and if the ECM isn't asking it ain't happening .......in my experance if it's asking you're headed for trouble ......

 

Volvo Trucks with EPA 2010 Volvo engines don't do active regenerations on the road as its set up to clean itself during normal operation passively but our shop does run periodic forced regenerations to keep things clean via the Volvo Link software. Otherwise it won't let you run a parked regeneration unless:

A: the soot level gauge is at the #2 mark, triggering the Park Regeneration needed warning.

Or

B: The SCR system NOX sensor detects low performance due to DEF crystals plugging the SCR catalyst and triggers the parked regeneration needed warning and SCR Performance Low warning. This sometimes occurs during below freezing temperatures since the Volvo emissions system doesn't do on road active regeneration. It's called a crystal sublimation cycle. The DPF gets cleaned as a bonus.

Not running the crystal sublimation cycle asap can trigger the 5 mph derate condition.

In other words every engine has its headaches, lmao.
