Passat 2004 1.8T 5 SPD Man Trans
Engine code indicates "Speed Sensor". Local mechanic has replaced engine speed sensor twice , cleared code and engine light returns on dash after 30 miles (twice). Still indicates "Speed Sensor" as fault. Mechanic replaced ring sensor in 5 SPD Manual transmission as possible cause as the "Cruise Control" indicates an "ON" condition on dash but will not engage and engine light is "ON" when running. Mechanic say everything indicates NORMAL including the speedometer. He is stumped as to the real fault, any ideas or direction?
