I have a Audi A3, speedometer reads ~6km/h too high compared to GPS and various "speed-showing signs" I've driven past.

My 18 year old A3 reads about 1mph higher than the true speed at motorway speeds. It's pretty spot-on, which is very unusual.

    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.
