DPF Problem? Back On The Road - Often Same-Day.

No - clamps are priced separately and quoted at check-in, not baked into the flat-rate. Here's why almost everyone says yes to new ones: a clamp that's already been used once tends to lose its seal when it's reused, no matter what shape it looks like it's in - and that often shows up later as exhaust smoke or a leak. If that happens with a reused clamp, it falls outside our cleaning warranty. New clamps are what keeps the whole job covered. About 99% of our customers choose new clamps once we explain that - it's a small add at check-in, but it protects the work we just did.

No - any brand meeting the 32.5% urea standard works the same; premium DEF doesn't perform any better. Sealed at room temperature it's good for about 1–2 years, roughly half that in a hot garage, and about 3 months once opened.

We'd strongly recommend against it - a power washer can physically destroy the ceramic honeycomb inside, and even plain water without pressure can turn ash into a hard, cement-like clog. If you need to get moving in a pinch, compressed air only, then bring it to us to do it right.

If it's asking more than once, or it's becoming a regular pattern, that's usually a sign it's time for a DPF cleaning. If we check it and the filter comes back clean, we'll also look at whether an ECM calibration issue is behind it.

No - we operate strictly in EPA compliance and don't perform or offer emission deletes. A $120 computer diagnostic finds the real cause instead of just hiding the warning light.

Any vehicle type qualifies for Same-Day for a $200 add-on, subject to daily shop capacity. The one thing that can push a job to Next-Day is the filter itself - if it comes off heavily clogged, it may need more time than a same-day slot allows, regardless of truck type.

That's the engine computer protecting itself from a serious aftertreatment fault - usually a clogged DPF, a failed regen, or a DEF/NOx system issue. We run full diagnostics on the exhaust aftertreatment system to pin down the actual cause before quoting anything, rather than assuming it's automatically the filter.

30 days or 15,000 miles on the cleaning itself, as long as the filter's ceramic core is intact and there's no undisclosed underlying engine issue. We stand behind the exhaust-system work we do - the filter, its seals, its flow. If the root cause turns out to be engine-side (oil or coolant reaching the filter, for example), that's flagged and discussed with you before we start, and it sits outside the cleaning warranty.

Every filter gets probe-tested before any cleaning starts. If the ceramic core is cracked or burned through, cleaning it isn't safe or reliable - we'll tell you before doing anything and quote a replacement instead of charging you for a clean that wouldn't hold.

Yes - a $150 CARB Compliance Test confirms your truck meets emissions standards, useful if you're heading into California or dealing with a weigh-station inspection.
