A matching connector and housing do not establish that a used mechatronic unit is suitable for a vehicle. Hardware, software, transmission variant and supported adaptation requirements may differ even when the parts look similar.
Compare the complete identities
Photograph both labels and keep the donor information supplied by the seller. Record the gearbox code and vehicle details. Ask a competent specialist to confirm the proposed route before fitting, coding or modifying the replacement.
Do not discard the original unit or assume its entire data can be transferred safely to any similar assembly. A successful identification read is not proof of operating compatibility. If the replacement has already been installed, preserve all error messages and the tool log. Explain what functions work and what fails. The assessment should state any compatibility limits clearly so that further parts or programming are not purchased on the basis of physical appearance alone.
