Speedo Inaccurate

[Glennb]

according to "authorities" here in VIC, going 5km/h over the limit will automatically cause you to spear off the road and into a tree....

Last time I watched ACA they said

Stopped reading there hehe. They're as credible as the ranga running the country right now......

Just one question if possible. Is the MFD display of speed closer (not the average speed display) to accurate than the speedo?

You tell us?
It completely depends on your car...

Makes you wonder doesn't it? In my VW Jetta 1.6 TDI (as in most VW s I assume)
There are 3 speeds. One the digital readout; two the old needle on the dial and three the one you get if you put your watch together with the odo.
AND. They all disagree with each other AND they're all not correct.
Maybe doing mental calculations of 107% of speed limit signs is a cunning way VW has to keep my mind constantly working and alert , thus keeping my travel experience a safer one???????
Love my Volkswagen.
Love my GPS. Happy motoring.

Interesting stuff. My TSi MFD is the same as the analogue gauge, which is 6% slower than the GPS (and Ive tested 2 GPSs against it)
The odometer is spot on when tested against the 5KM test "tracks" on the highway
Keeps the brain active calculating 6% error and driving to that. OR - believe the GPS. OR - just don't speed

Yeah Brian, my MFD speedo and analog speedo are identical too. But I know a lot of people here have mentioned that their's are not. I think that it may have been changed to be identical at MY09 or something like that as it used to be a common thing newbies would post about...

Ditto for me - analogue and digital speedo are the same - although the digital sometimes lags the needle by a couple of seconds.

At an indicated 110kmh the GPS says I am doing 104kmh... so the speedo is reading 6kmh high at that speed - but around 80kmh is only 4 or 5 out, so it seems to work on a percentage. I've been through speed traps at an indicated 121kmh (actual 115kmh) and the police were not interested.

The odometer is accurate when measured against the 5km marks on the highway.
