I just had one put in my wife’s car (2005 Jetta wagon). I had to have two extra modules. One was for the coded key. They took the valet key and cut the end off and mounted it with a module, and one module to talk to the CAN bus. The Alarm/Remote start was designed to be used with a diesel. It has the glow plug wait to start, and turbo timer shutdown.
The wife loves it. She can start the car from inside the office (about 800 ft). This is what we have, a search on the net will show plenty of others.
