I was wondering if I put a different profile of tyre on if it's possible to adjust speedo reading electronically or does it also take an analogue output too for the dial?

Anyone know?

Thanks

You can do some adjustment using VCDS and adapting instrument cluster, however usually only 2 settings are selectable, about 3.5% apart.

In practice, this allows correcting ~3mph at 60mph, and was originally put in due to slight differences in final drive between 5 and 6 speed gearboxes. I know about it because I swapped 5spd gearbox to 6spd on my Octavia and had to adapt the speedo as it was overreading 4mph at 30mph. Mk1 Superb Instrument Cluster adaptation looked the same, so probably Mk2 has this too as there are still 5 and 6 speed boxes around.

But if you change tyres / rims as per manufacturers recommendations (ie new size/profile listed on the fuel tank flap), then no adaptation is neccessary as overall diameter of all listed tyre/rim combinations is the same, 630mm+-2mm.

Ok thanks for quick response

It`s "so last season" to watch the speed from the car`s own speedometer. I always look the speed from the navigator, it`s basically always right.
