Forced Regen Service in Vancouver, WA

Your truck is in derate. You are losing money by the mile.

That check engine light came on somewhere around the I-205 interchange. Your truck dropped to 5 mph derate mode. You limped it to the nearest lot and now it is sitting there, burning daylight, while you figure out who can fix it.

The dealer wants you to tow it in. Two days minimum for a DPF regen appointment. The local shops are booked. Meanwhile your freight sits.

We drive to your truck. Plug in our diagnostic tools. Run the forced regen right there in the parking lot. Clear the fault codes. Verify the system is clean. You drive out under full power.

What a forced regen actually is

Modern diesel trucks use a diesel particulate filter to trap soot from the exhaust. The truck normally burns this soot off during highway driving through passive regeneration. When the filter gets too clogged and passive regen cannot keep up, the system throws codes and puts the truck into derate mode to protect itself.

A forced regen uses dealer-level diagnostic software to command the truck to burn off the accumulated soot at high exhaust temperatures. It takes 30 to 90 minutes depending on how clogged the filter is. No parts to replace. No filter removal. Just a controlled burn cycle monitored by a technician who knows what they are looking at.

When a regen is not enough

Sometimes the DPF is too far gone for a regen. The soot load is too high, the filter is damaged, or there is an upstream problem feeding too much soot into the system. Leaking injectors, a failing turbo, or a cracked EGR cooler can all cause excessive soot loading.

We diagnose before we regen. If the filter needs cleaning or replacement, we tell you. If there is an upstream problem that will just clog the filter again in two weeks, we find it. No point running a regen on a truck that is going to derate again next Tuesday.

Common trucks we service in Vancouver

Freightliner Cascadia and M2 trucks running Detroit or Cummins engines. Kenworth and Peterbilt with PACCAR MX engines. International with Navistar powertrains. Hino, Isuzu, and Ford commercial trucks. Every modern diesel with an aftertreatment system can derate, and we carry the diagnostic software for all the major platforms.

The Vancouver DPF problem

Stop-and-go driving kills DPF systems. Trucks running short routes around Clark County, making deliveries in Vancouver, crossing the river to Portland, idling at the Port of Vancouver terminals. This is the worst possible duty cycle for a DPF. The filter never gets hot enough for a full passive regen, so soot accumulates fast.

If your fleet runs local routes in the Vancouver-Portland metro, DPF regens are not a once-a-year event. They are a regular maintenance item. We can put your trucks on a proactive regen schedule so derate mode stops being a surprise.

On-site, not at a dealer

Dealers charge a premium and make you wait. A forced regen takes an hour of actual work. Towing to a dealer, waiting for an appointment, and picking up the truck turns that into three or four lost days.

We come to your yard, your lot, or wherever the truck is sitting. Plug in, regen, clear codes, confirm operation, leave. Your truck never moves except back onto its route.

After hours regen service

Your driver calls at 8 PM. Truck derated on Highway 14 near Camas. The dealer is closed. The shops are closed. We are not. Call us and we will send a tech with the diagnostic laptop to get that truck running tonight.
