They all seem to do it,,Tyre and wheel sizes can affect it also.
On the other hand my classic car ''under reads''so I've got to be careful. Anyone not having an 'IPK' MPH reading,then I found a free app' on my mobile gives a digital readout and also can give a HUD heads up display on the windscreen when placed on the dash. Ken. |

As stated, a 10% over read is pretty standard in the UK... innit..

I have a Scan gauge permanently connected to my OBD2 port and it, like everyone's sat nav, shows an error of 3mph at 30 and 5mph at 60. While talking about this subject does the law still allow 10% error for speeding or has this come to be a generally understood phenomena due to all our speedos over reading?
In my trucking days I always kept my truck on the limiter(55mph) and never once got pulled up for speeding in roadworks. Due to what I have read on this thread about speedos being set to read higher than actual speed in a truck this is downright bad practice. With a digital tachograph any speed over the limit(85kph) comes up as an overspeed and UK police have been known to issue fines and points on this evidence. This speed is actually below the speed limit for trucks on motorways which is set at 60mph. How can that make sense? I know it is an EU rule (85kph) but the Spaniards have an exemption. Why don't we?

Both the analogue dial and digital readout get their information from the same source - the OSF ABS wheel sensor.
Interestingly on the V8's where the digital readout was factory enabled, it has been reported that it matches the analogue speedo, so they must have tweaked something. |

In effect, this means that you'd have to be travelling at an actual speed of 36MPH in a 30, 47MPH in a 40, 58MPH in a 50 etc before you'd get a ticket. But, it's up to the force concerned (and indeed to individual officers) where they draw the line. |
