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.
Never again, VW auto group…
- storus 3mo agoJust use the speed reported by your GPS. Most navigation apps show the GPS-based speed.
- cuu508 3mo agoA 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.
- jabroni_salad 3mo agoI have a GTI and with cruise control on, the speedo and my phone's gps reads exactly the same speed.
- embedding-shape 3mo agoI have a Audi A3, speedometer reads ~6km/h too high compared to GPS and various "speed-showing signs" I've driven past.
- mnw21cam 3mo agoMy 18 year old A3 reads about 1mph higher than the true speed at motorway speeds. It's pretty spot-on, which is very unusual.
- embedding-shape 3mo agoAh, 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.
- technothrasher 3mo agoI believe the only Audi car made in Mexico is the Q5. My US model 2025 A3, btw, is dead on (+/- 1 mph).
- martinpw 3mo ago> When I talked to the dealers, they said that the speedometers only have to be accurate +/- 10% according to the SAE specifications. 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.
- gene91 3mo agoWow TIL. I have observed that my rental cars in Europe all have faulty speedometer. Multiple brands, multiple countries. So this is why.
