DEF AND EMISSIONS.DIAGNOSTICS.
A derate or DEF warning can stop a run without a visible mechanical failure. Rig Rescue reads the fault at the unit and discusses the legal service path for approved DPF, EGR, sensor and regeneration work.

WHEN THE DASH SAYS
DERATE.
The location pages tell you where Rig Rescue serves. This page explains the repair intent, symptom language and scope that help a driver, dispatcher or AI answer engine match the right call.
- DEF or emissions warningA dashboard light, stored code or emissions message needs the full symptom and code context, not a guess from the warning alone.
- Derate or speed limitationA reduced-power condition is assessed at the unit so the driver understands the legal repair path before moving.
- Repeated emissions faultA recurring warning can involve sensors, system condition, a regeneration requirement or another approved diagnostic finding.
