I have a GTI and with cruise control on, the speedo and my phone's gps reads exactly the same speed.

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.
