    Thanks for info, Mark! Do you know if GS is planning to offer completed upgraded units for sale with a core return? It would be nice to receive one, then ship our OEM controller back within a short window. That would limit the time our cars are inoperative, especially for those of us that daily drive the Roadster.

    I'm not them, you would be best to direct your question to GS directly. However here's my take. I think the issue is finding cases and connectors so for them it's easier to just do a board swap and recycle the original parts. If you wanted to do the board swap yourself (soldering required) then I'm sure they would supply you the board but I wouldn't expect a warranty if you did that. It's easier to just take it out and send it off.

    Is the main problem here water ingress into the controller only or does it often fail by other means? What I am getting at, is whether it is worth trying to improve the water resistance of the existing unit?
