• Where the vehicle is close to a model-year change, the VIN is a more reliable guide than the registration date.
• Electrical parts are the least returnable category we sell, because once a module or sensor has been plugged in it cannot be resold as new.
• Where a module needs programming after fitting, confirm that before ordering. A correctly numbered module that is not coded to the vehicle will not work.

A part that fails early usually points at an installation fault or a worn component nearby rather than at the part itself. Fitment lists are a guide rather than a guarantee, because the same model year can carry different parts depending on the production break and the option code.

The part number is the thing to verify. Where the old part carries no legible number, a VIN and a photograph are enough for us to identify it. Handed to the carrier within one to two business days from our US warehouse, free over $59.
