So just how inaccurate is the polo speedo??

[pomme]

Driving home to the city 30 minutes ago... on wynnum road morningside, between gibson and beverly st (for those that know the road), and *flash*. Took a second to realise what had happened, but i look down an i'm doing about 82 (in a 60).

Although i'm pretty outraged they have a speed camera out at 11:10pm and the road was so dead, i was pretty impressed that it managed to get me parked on the other side of a 4 lane road (2 each way)

Anyway... i was thinking the speedo is about 8% out isn't it? Which would equate to around 75 real speed...

I'm just trying to work out how many points are gone.

I may get lucky and the photo doesn't turn up... either way... she'll be looking hot, i'll add it to the collection.

Bugger Sounds like u need to use cruz controll lol From memory at 100kmh on the speedo the real speed is 94kmh but could be wrong.

"Although i'm pretty outraged they have a speed camera out at 11:10pm" They got you didnt they ppl speed no matter what time it is.

hey dude sorry to hear that.
from memory, there is an error around 100+, but the error below 100 isn't much at all...80 would be like 78 or so...etc.

nah....

There is an error pretty much the whole way through the speedo.

GPS systems show you how **** the current speedo is

and to the topic.

If you want to know what speed you were doing. Put your computer onto the average speed mode. Than go to 82kph. Press the reset button. And the first speed which is shown is normally the correct speed.

If I sit the speedo on 109km/h I'm doing 100km/h actual.

vw apparently puts in a deliberate error throughout the speedo range so that you should never be doing more than the indicated speed.
I have found this with our nbc and our polo.

I still had to correct my ECU's speed by -2 or -3% to get it to read correctly, via my Scangauge (see my separate thread on that device). Might be just my tyres. So yeah, always use a GPS from time to time to get a correct reading.

Agree with the Polo's speedo being a POS. Especially when you reach 80kph, it's a bad joke. For a definition of a clear, easy to read speedo, try the Honda Accord Euro. Or better yet, any new Civic with its motorcycle like big letter display. (Provided it is calibrated correctly that is, can't say anything about that).

This is a crap philosophy by VW, imnsho. It's much better to have an accurate reading so that you know what you are doing, rather than it being a guesstimate of something.

Besides, if you think you're doing 80kph when it says 80 yet you're really only doing 72kp, any time stop to wonder why people get impatient with you when you 77-78 (apparantly) as you actually see it on the speedo? In real life you'll be going 10-15 kph less than the limit! (UGH!%#@!)

Tried that today, 65 on the speedo shows up as 60 on the computer

[pomme]

100 came up as 92. I'll steal a gps off someone

i agree... i have found that all we do is sit 5k's over the limit to compensate for it.

[Funkdancer]

Apologies for using the word that combines bull with manure, didn't mean to upset anyone.

Yep having to compensate for the speedo is a bit suboptimal, all manufacturers do it to some degree (e.g. my Accord is 4%) but in the Polo it has been taken a degree too far. When money and your license is on the line, we deserve to have proper information about the speed our vehicle is doing.

Another thing is that the odo will be displaying an over inflated figure, which will affect resales price.

How would we go about getting it fixed / adjusted?

[PoloGTi]

We could just send VW Australia an email asking why and by how much its out???? Might give us the real reason for doing it.

[ACTGTI]

Hate to be pedantic, but my Peugeot 206 GTi180's speedo was 100% accurate at all speeds! So, not all manufacturers provide inaccurate speedos. This was apparently done by measuring speed at each wheel through the ABS sensors, then taking the average of all 4 wheels.
