Hi! I hope someone can help me to solve what it causing my speedometer needle to jump....like when I´m doing actually 90km/h...it can "jump" to 230km/h and of course when it hits 120km/h , rear spoiler goes up.
Could this be connected with Vehicle Speed Sensor ? Do ABS-rings in the rear have anything to do with speed ??
Other thing is consumption readings.....it´s usually showing x 2 more gasoline than I´m actually using. (Vacuum sensor broken ???)

(Again, you can answer also in german....I can read better than write :D)
