    Webasto unlock to start from pin1

    Hello. I have an webasto thermo top Z from an bmw x5 2004 and i want to put it on a bmw e39 530d. The problem is that i cannot start it because it is locked. I understand from another persons , this unit must be unlocked to start from pin 1 or pin 3 from 6 pin conector,before i can start and use it. It is anyone who can help me with an information,how can i unlock the unit? Must be recoded with ncs dummy? Can be unlocked with inpa,sss,rheingold,etc or i need an dedicated software for WTT?

    There is a Webasto diagnostic program that you can use to work on it via pin 2. I've been repairing these for a while now (my 530d is on its 3rd one lol). Search for "Webasto Diagnostic Cable" on ebay.

    Also, the e53 doesn't have the coolant pump on the webasto, while the e39 does. They are identical otherwise. I'm not sure if the pump on your e39 will still be working.
