Check your module version
Compare each number and suffix with the label on your part. The listed type helps identify the module; it does not by itself confirm the HW hardware revision, SW software version or compatibility with your vehicle.
Prepare your quote request
Provide the vehicle make, model, year, engine, VIN, symptoms and fault codes. Attach photos of the label, connectors and housing; include all revisions 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.
