Hi, returning member here but had my '98 Beetle for years. My speedo needle fluctuates about 15 or 20mph while driving on the highway at 65. When I put the cruise on the car tries to keep the speed steady, but with the speedo doing that the car bucks really bad. No codes using my Ross Tech Vag Com. Anyone else have this problem, or ever heard of it? My transmission is the 01M, but not exactly sure what one, andthe vehicle speed sensor was replaced by the dealer when I got the car. There is 185,000 miles on it. Thanks in advance for any help.
