What an AdBlue delete is

AdBlue (SCR) diesels inject a urea solution into the exhaust to cut NOx. When the pump, heater, tank sensor or NOx sensors fail, the A4 warns the driver and can limit the engine or refuse to start. An AdBlue delete recalibrates the engine software so the SCR system is switched off and no longer needed.

Why A4 owners ask for it

  • No AdBlue to buy or top up
  • No countdown-to-no-start warnings from a failed SCR system
  • No AdBlue pump, heater or NOx sensor replacements
  • Often done with a Stage 1 remap in the same visit

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 TDI 286hp typically goes from 282bhp to around 320 to 340bhp at Stage 1, and Stage 1 plus AdBlue delete is £349.
