Forced regen service in Mount Shasta
Your DPF light came on climbing toward the Siskiyou Summit. The truck derated and you are crawling on the shoulder at 5 mph with a line of cars honking behind you. The nearest shop that can run a regen is 60 miles south in Redding.
Fleet Nation runs forced regens on-site in the Mount Shasta area. We come to your location, clear the codes, and get you back to full power.
Why regen problems hit hard on the Siskiyou corridor
Mountain driving is a DPF nightmare. The grades push engines hard, loading the DPF with soot. Then the descents drop exhaust temps too low for passive regen. The DPF fills up and the truck derates.
Chain control delays make it worse. Hours of idling in freezing temps load the DPF and never get hot enough to burn anything off. When the road opens, the truck immediately derates because the DPF is packed full.
Cold weather adds another layer. DEF systems freeze. Doser injectors clog. Sensors read incorrectly in extreme cold. All of these trigger aftertreatment codes.
What we do on-site
Factory-level diagnostic tools to read the full aftertreatment code history. We run the forced regen at your location. Takes 30-60 minutes for a standard regen.
If the regen will not complete, we diagnose deeper. Failed DPF pressure sensor, bad doser injector, cracked DPF core, frozen DEF lines, or DEF quality issue. We repair on-site when possible.
Aftertreatment components we service
DPF forced regen. DOC inspection. SCR catalyst evaluation. DEF doser injector replacement. DPF pressure and temperature sensors. DEF pump and line repair. EGR valve cleaning and replacement.
Cold weather aftertreatment problems
Frozen DEF lines and pumps are common on the Siskiyou corridor in winter. The DEF system shuts down, the truck throws codes, and the engine derates. We thaw frozen DEF components and repair damaged lines on-site.
Call Fleet Nation at 530-925-7775 when the DPF light comes on. Do not drive derated longer than you have to.

Forced Regen Service Questions
Straight answers for Weed fleet operators
How long does a forced regen take?
30-60 minutes for a standard regen. Longer if the DPF is severely loaded or there is an underlying component problem.
Can you do a regen in winter conditions?
Yes. We work in cold and snowy conditions. Our trucks are equipped for winter service.
What if the regen will not complete?
A failed regen means a deeper problem. Bad sensor, failed doser, cracked core, or frozen DEF system. We diagnose and repair on-site when possible.
Do frozen DEF lines cause regen problems?
Yes. Frozen DEF lines shut down the SCR system, which triggers codes and derates. We thaw and repair frozen DEF components on-site.
What truck makes do you work on?
Freightliner, Kenworth, Peterbilt, International, Volvo, Mack. Factory-level scan tools for all major makes.
How much does a forced regen cost?
Depends on whether it is a straightforward regen or involves component repair. Call for a quote.
