Probably made worse by the fact that _every_ VW brand car I’ve driven has read about 10% high on the speedometer. I think I’m going 100 kph, but timing using the km markers on the highway show I’m going about 90.
When I talked to the dealers, they said that the speedometers only have to be accurate +/- 10% according to the SAE specifications.
After DieselGate I assumed that the high reading was to game the fuel consumption game.

I believe the requirement is only one way - they can read high by a certain % but they cannot read low. Which makes sense. But that means in reality they will usually read a little high.
A little nice thing the cars could do is automatically calibrate the speedometer from GPS when on a long stretch of a road. You would get the accuracy of GPS and the reliability of speedometer even when in city jungle, underground, during slow speed manoeuvres etc.
Ah, mine is quite precisely 10 years younger, and also European if that matters, sounds like yours might be Mexican if it's in the US unless I'm mistaken. I guess there is some tuning process at the end of fabrication/production, maybe just "wild luck" either way.

Never again, VW auto group…
