What drivers call us about
- A DPF or regen light that won’t go out
- A regen that won’t start or won’t finish
- A DEF warning, with or without a full tank
- A truck that’s lost power after one of those lights came on
Soot, ash or DEF?
Three different problems can look like one light on the dash, so it helps to know which is which.
- Soot is what the filter traps as you drive. A regen burns it off.
- Ash is what stays in the filter after a regen. Another regen won’t clear it, and that’s where a DPF cleaning comes in.
- DEF is a separate system from the filter, with its own tank and its own warnings.
You don’t need to work out which one you have. Tell us what you’re seeing, and the mechanic takes it from there.
What to tell us
- The exact wording of any message, and which lights are on
- Whether the truck has lost power, and how much
- When it last ran a regen, if you know
- Whether you’ve just filled up with DEF
- The make, model and year, and where you are on I-40 or I-27
At the truck, or at a shop?
DPF cleaning, regens and DEF system repair are all work we do at the truck. If the mechanic finds the cause is somewhere else in the engine, they’ll tell you what it needs and whether that means a shop.
Where we cover
We're open 24/7. We cover Amarillo, Canyon, Lubbock, I-27 and I-40 from Vega to Groom, and can stretch farther across Texas. Call with the location and we'll tell you whether we can get there. We don't promise an arrival time on this site, so ask on the call, and ask for an estimate before any work starts.

These reviews aren't about DPF or DEF work specifically.
… They are not a parts changer, you go there for a problem, they find out the problem and fix it.... 5 Star !!! …
Very good service, great customer service, prices and a professional team
Frequently asked questions
- What's the difference between a regen and a DPF cleaning?
- A regen burns off the soot the filter has trapped. A cleaning deals with what a regen leaves behind, which is ash. Which one the truck needs is for the mechanic to find out.
- The truck has lost power. Can I keep going?
- Tell us the message on the dash before you decide. If it's telling you to stop, stop somewhere safe and call.
- The DEF tank is full but the warning is still on. Is that something you handle?
- DEF system repair is work we do at the truck. Give us the wording of the warning and any fault code.
- Do you work on my make of engine?
- Ask on the call. Have the make, model and year ready.
