There are 3 gears available for the end of your speedo drive. I found this out by accident when my 020 came with a green gear instead of the standard white. I have since found out there is a red as well. The green one is the one you are after for bigger wheels to slow your speedo down if necessary after checking wth GPS.

Red has 15 teech, white has 16 and green has 17

mmmmm i have just been driving without checking with a gps.what is involved with changing the gears where do I get them from (main dealer)?

I think you need the red one to make your speedo faster, green for little wheels - don't know what I was thinking. They simply clip on, 10 second job. Getting hold of one will be another story

Today Tonight/A Current Affair (I can't remember which one, they're both chequebook/tabloid journalism at it's worst) have a story on tonight about speedo calibration. If you're lucky, they may actually speak to someone worthwhile and accidently put some useful information in amongst the rest of the garbage the story is made up of...

hahahahahahahahahaha...
hahahahahAHAHAHAHAHAHAHAHA...

*giggle* I suppose it could happen. Honest journalism and all that...

Let me take a stab at it...

Speedo's are off, they are all under (no reference to ADR that says they can be under but not over).
Dealers/Manufacturers know this, but don't tell you because a services comes around quicker (in many cars).

Ummm...

...it's a consipracy with the fuel companies...
...and now onto another Aussie battler...

hahahaha and that would be very lucky...

i have found all my vdub speedos to be out.
our nbc over reads by about 3-4k's
our polo overreads by about 5k's
our jetta overreads by about 4-5k's
but the trip computers are accurate. its the speedo indication that is altered not the distance you travel.
