We are the proud owners of a 2002 e4. I’m big on modifying my other toys and the last few days have pointed me here on a number of topics - ton of good information on the site. On the search for user manuals. I think mine was modified because it seems to hit 35 on gps. the digital gauge shows -04 so I’m buying a new parking brake switch (thanks to this site).
UPDATE: I plugged in my VIN on Polaris’ site and had 2 recalls, 1 of them was a parking brake the other a controller DC board. For $95 they are coming out to my house and performing the whole recall service. That should cure my -04 code. Woohoo!
