Fitment notes

Getting the exact match for your nox sensor matters - vehicles share families but rarely share parts 1:1. Use the points below as a starting checklist, then enter your registration and ask the responding supplier to validate fitment before you commit.

  • 1Confirm the exact vehicle: make, model, generation/chassis code and registration date - facelifts often change part numbers mid-cycle.
  • 2Match the OEM part number from the old unit where possible. Ask the supplier to cross-reference it against the offered part.
  • 3Check trim and option packs (e.g. M Sport, S line, R-Line) - these can change brackets, sensors and looms.
  • 4Engine code and Euro emissions standard must match - Euro 5 and Euro 6 DPFs are not interchangeable.
  • 5Check whether sensors (NOx, lambda) and brackets are included.

What's included

Test evidence

Ask the supplier what checks were completed and request supporting evidence.

Warranty terms

Check any cover offered by the supplier in the written quote.

Original photos

We ask yards to include real photos of the actual part.

Returns and rights

Review the supplier's return terms; your statutory rights remain separate.

Before you buy

Emissions parts (DPF, cat, EGR) must match your Euro standard - fitting the wrong unit can cause an MOT failure.
