Speedo Inaccurate

[Jeats]

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....

Not to mention every km/h that you are over, a kitteh meets its end

Seriously?

/me starts driving around at 50km/h over the speed limit everywhere...

Did the avg speed reset thing yesterday, which is kind-of annoying because it reset my avg fuel consumption & hours runs as well.....

100kmh on the speedo = 97kmh on the GPS = 95kmh on the digital readout. So if the digital readout is accurate (I believe the GPS is more accurate) then there was a >10% (12%-13%) difference between analogue & digital speeds when the car was fresh from the factory. No wonder everyone in the fast lane was zooming past.

my speedo shows 140km/h, but the GPS says 130km/h...kinda feel ripped off, but VW tells me with its within tolerance.

I said to them will they refund me the 10,000kms worth of depreciation when my car hits 100,000km but has actually done abit over 90,000km....

they had no answer...

The speedo & odo are independant. I agree the odo still reads wrong but it isn't as bad as the speedo. You need to use one of those 5km long "Odometer check" strips that they have on motorways - the blue signs and use your tripmeter.

[Corey_R]

brad, if your ODO is wrong, then that would be why your 'trip meter reset test' failed to get the same reading as a GPS.
Your ODO shouldn't be wrong unless there is some variation in your wheels/tyres from stock.

On my R, doing the 5km long check is perfectly accurate (within the errors of that check anyway), and the ODO matches the distance reported via a Tom Tom GPS, and the speed matches the trip meter average etc.

So in your case, adjusting the base value in VCDS to get the ODO back into an accurate position would be beneficial to you. It won't help the speedo being out.

Last time I watched ACA they said

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

lol what he said

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

[Corey_R]

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.
