Fitment notes

Getting the exact match for your alternator 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.
  • 4ECUs are usually coded to the car - confirm whether the supplier offers programming or describes the unit as 'plug & play'.
  • 5Cross-reference the unit's hardware/software part number, not just the chassis fitment.

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

Some ECUs require coding to your vehicle. Confirm with the supplier whether programming is included or if your garage will need to code it.
