The cruise control on my 2012 VV was driving me nuts. In 6th gear it would constantly readjust speed creating a very unsteady cruise. It wasn't even noticeable on the speedometer or GPS, but I could feel it in the pit of my stomach as it would slightly lurch about every second. Today I got rid of the vampire connectors on the PCV. I soldered pigtails with blade lugs on the appropriate wires and put spade connectors on the PCV wires. No more surging or lurching and I don't have to worry about the connectors or wires corroding or breaking. A worthwhile mod.
