A clogged Diesel Particulate Filter (DPF) will trigger a check engine light, cut your engine power, and put your truck into limp mode fast. When your DPF warning light comes on, every mile you push it risks turning a routine forced regen into a full DPF replacement. Capital Diesel handles forced regen service onsite, at your location, so you avoid the tow and get back on the road without unnecessary delay.
Our diesel mechanics come to you fully equipped to perform a forced regen using professional-grade diagnostic and regeneration tools. We connect to your truck's ECM, confirm the DPF soot load, and initiate a controlled stationary regen that burns off accumulated particulates and restores your filter to proper operating efficiency. The entire procedure is performed at your location with no need to visit a truck repair shop.
Capital Diesel serves Sacramento and the surrounding area within a 60-mile radius, including West Sacramento, Elk Grove, Roseville, Rocklin, Folsom, Davis, Woodland, and Citrus Heights. Our mobile truck repair technicians are dispatched directly to your location and arrive onsite in 30 minutes or less. Whether you are parked at a truck stop, a job site, or on the side of the road, we come to you.
Our team works on all major diesel truck brands including Kenworth, Peterbilt, Freightliner, Western Star, Volvo, International, Mack, Hino, and Isuzu.

What is a forced regen and when does my truck need one?
A forced regen is a controlled procedure that burns off soot and particulates built up in your truck's Diesel Particulate Filter (DPF). Your truck typically needs one when the DPF warning light comes on, engine power drops, or the truck enters limp mode due to a clogged filter.
Can you perform a forced regen at my location in Sacramento?
Yes. Capital Diesel is a mobile truck repair service covering Sacramento and the surrounding area within a 60-mile radius. We dispatch a technician directly to your location, whether you are at a truck stop, job site, or loading dock, and arrive in 30 minutes or less.
How long does a forced regen take?
A standard forced regen typically takes 45 minutes to 90 minutes depending on the truck, DPF soot load, and engine condition. Our technician will give you a time estimate after connecting to your ECM and reviewing the diagnostic data.
What happens if my DPF is too clogged for a forced regen to work?
If the soot load is too high for a stationary regen to complete successfully, the DPF may need to be removed for a professional cleaning or replaced entirely. Our technician will diagnose the situation and walk you through your options with clear, honest recommendations.
