What an EGR delete is

Exhaust gas recirculation sends part of the exhaust back into the Quattroporte intake to cut emissions. Over time the soot builds up in the valve, the cooler and the inlet. An EGR delete recalibrates the engine software so the system is switched off and the engine breathes clean air only.

Why Quattroporte owners ask for it

  • No more sticking or clogged EGR valve faults
  • Less soot carried into the intake and inlet manifold
  • No EGR warning lights or limp mode from a failed valve
  • Often done with a DPF delete or a Stage 1 remap

How it works

  1. Diagnose

    We read the fault codes and live data first, so we know the state of the system and anything else that needs attention.

  2. Read the ECU

    We read the engine software, over the diagnostic port where the car allows it and with the ECU out on the bench where it does not.

  3. Calibrate

    The software is calibrated for your engine so it runs properly without the system, with no warning lights.

  4. Check and hand back

    We clear the codes, run full diagnostics again and check the car before it goes back to you.

Pair it with a remap

Most owners pair it with a Stage 1 remap in the same visit. The 3.0 Diesel 275hp typically goes from 271bhp to around 310 to 325bhp at Stage 1, and Stage 1 plus EGR delete is £349.
