Hi All, new to the forum but hoping you could help with a cruise control problem I've got on my 2012 beetle. My speed drops 5-8 mph every time the road curves to the right. When the road straightens out it begins to accelerate back to the set speed. Wondering if it could be related to a vacuum line or something? VW dealer has hooked it to computer and scanners and everything checks out fine. Any ideas or help would be greatly appreciated.
