Can't change the speedometer calibration with a VAGcom.

Most/all cars run a bit high on speed and mileage. Helps the car maker by

1. Making your warranty run out a bit earlier.
2. Makes you think you are getting better mileage than you are actually getting.
3. Removes the excuse about speeding due to the speedometer reading slower than you are actually moving.

 

I have access to a radar. I think it is just annoying that it is off 3 mph, my Chevy is off -2mph at all speeds. I know I am just being ****.

 

yes. yes you are.

 

fact is you cant calibrate your readings unless its digital, to simplify things your speedo is out by 3mph and that lower than the reading on the clock its called within parameters to save your licence

 

Pull the cluster and move the needle?
