These were failure prone; so much so, that vw removed them from the later models. So, people have many times; decided, to remove the broken portion and leave the wiring harness connected and just leave it that way, as a new one, will probably end up breaking again. As to replacements, I don't know; if they are still available from vw, contact your dealers part dept or look up on vw's parts site. www.parts.vw.com
As to the "lift mechanism"; what parts are you referring to (e.g. hydraulics, mechanical pars, etc)?
