Check your module version
Compare each number and its suffix with the label on your part. The stated family helps identify the module; on its own, it does not certify the HW hardware revision, the SW software version or fitment on your vehicle.
The part numbers on this page are used for identification. They do not guarantee interchangeability between different versions.
Prepare your quote request
Provide the make, model, year, engine specification, VIN or machine serial number, symptoms and fault codes. Attach photos of the label, connectors and housing; retain all revision identifiers and suffixes.
Service subject to quotation
Diagnostics, repair or module sourcing can be assessed for a quotation. Send a clear photo of the label and describe the fault so we can assess your request.
The price, feasibility, any module availability, the work involved and lead times are confirmed in the quotation before you approve it.
