Hi, I just bought a used 2013 SEL and was looking for a remote start. Since I have the push button start the tech would have to disassemble one of the two electronic keys and convert it to the remote starter otherwise I could buy a third key ($250.00) as a donor for the project. The Remote itself was $199.00.
When buying a new key they all have to be reprogrammed together.
The problem of finding remote starters has something to do with the encryption processes used by Volkswagon being more involved than that used by other manufacturers.
Just found your post and saw no replies, hopefully you found something by now, and if not hopes this helps.
