Look up a fault code, a repair price, or a shop.
Class 3 through Class 8, trailers, reefer units, and diesel pickups. Every price range comes from real invoices and says how many.
Try 3364, P226C, DPF cleaning, or a city name.

Guides and compliance
- DPF Regeneration Explained: Passive, Active, and ParkedThree different processes get called "regen" and drivers are rarely told which one their truck is doing. Understanding the difference is the single cheapest way to avoid a soot-loaded filter and the derate that follows it.
- Engine Derate Explained: What It Is and How Long You HaveA derate is the engine deliberately limiting itself. Which kind you have determines whether you have a thousand miles or a few hours before the truck is doing five miles an hour. Here is how to tell the difference and what the countdown actually looks like.
- What a DPF or EGR Delete Actually Costs YouEmissions deletes are illegal to sell, install, or operate, and the real bill lands on the truck owner long after the shop is paid. Here is the honest accounting — federal penalties, resale collapse, insurance and CSA exposure — and what actually fixes a truck that keeps throwing aftertreatment faults.
- Out-of-Service: What Puts a Truck Out at RoadsideAn out-of-service order stops the truck where it stands until the defect is repaired. The criteria are published, they are specific, and most OOS orders come from a short list of conditions that a driver can check before the scale.
- The Annual DOT Inspection: What 49 CFR 396.17 Actually RequiresEvery commercial motor vehicle needs a periodic inspection at least once every twelve months, performed by a qualified inspector against a defined federal standard. Here is what the rule says, who is allowed to sign it, and what the inspection actually covers.
- The CSA Vehicle Maintenance BASIC: How Repairs Become a ScoreRoadside maintenance violations feed a score that affects who will insure you, who will load you, and how often you get inspected. Here is how the weighting works and which repair decisions actually move it.
