    How to replace a BCM? (2005 T5)

    Hi all
    Just joined as have a specific problem.
    I have a faulty BCM on VW Transporter 2005 and have been told it is possible to replace by recoding the new one.
    I have searched the forums but unable to see any simple instructions.
    Please, please could someone provide me with a dummies guide, step by step on how to do this, as I have no experience using VCDS?
    Thanks - and keep safe!!

    Hi and welcome.

    The T5 does not have a single BCM. BCM functions are split between the Central Electric Module at address 09 and the Central Convenience Module at address 46. Which of these do you intend to replace?

    Please post an Auto-Scan from this van in its current condition for context.

    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.
