Speedometer Correction

OP i've often wondered this myself and im suprised it isn't part of a major service, i guess thats due to it not being easy to do/fix maybe...
Because putting cars on a rolling road and calibrating the speedo costs a lot of man hours/money, unless it is an adjustable electronic speedo.I had an after market electronic speedo in my last hot rod, and I set it dead on, to a GPS system. It is surprising how slow most people go through speed cameras when running off of factory speedometers......

OK - wonder if a quick thread bumb can help me.............Just bought a Cayenne S diesel, and the speedo reads 8% fast. Swopped an Audi A8 for it, which read 2% over. 2% I can live with as a safety net, but 8% is ridiculous.....Yes, I can look at my Snooper, but as it moves between cars it won't always be present, and I'd rather have an accurate speedo for setting the cruise and doing trip computer calculations.
So, the (I thought, wrongly!) simple question I've spent the last 2 hours searching for an answer to is this - can a modern digital speedo (2017 car) be adjusted by a main agent, or do I have to go rogue and fit a "yellow box", which I suspect would rule out getting an OPC warranty?
All helpful comments appreciated.
Thanks
