I'm about to buy a new speedo cluster for my Polo 6r, and I'm guessing the milage is stored in it, so when I install it my milage will be wrong? Is there any way to change the milage on it?

there are several tools to do so. but did you realise you also need to deal with your immobiliser?

I found this video but it's on a 2001 Toyota, do you have any idea if it would work on the polo?
He does the odometer like halfway through the video.
I also just ordered a Hex-V2 so hopefully that will be enough. All other searching has led to nowhere except for that vid.

After some reading, seems like it might be much easier swapping the plates between the two but I'll have to see when it arrives.
If I just swap the plates from MPH to KPH will it still match the real speed or does the speedo needle need to be changed etc?

Change the dial facia, providing the increments are the same the needle doesn't need asjusting. Make a note of where the needle is when you take it off and put it back on. Any change or rotation to the stepped motor will put it out of wack. Make sure the donor clocks have the same min and max values. Only if the top end is stepped will it need re-coding.
You will need to change the region on the clocks by coding them to amend the odo. The speed display setting is a setting in the GUI I believe.

You can change the dial(s), but you will need to change the scales with VDOeditor.
You will need a serial programmer with SOIC-8 clip:
You can find a guide on how to use the serial programmer with VDO dashboards I made here: viewtopic.php?f=56&t=76679

If you swap the dials you will indeed need to change the scales in the eeprom to make the needle show the correct speeds.
If you don't want to disassemble your cluster to read out the eeprom, I have developed some client/server toolset which allows me to remotely access your cluster (to read/write eeprom, or immo, or mileage) and can be used which cheaply available canbus cables.
