Yes they do Jordanian
Also the speed sensors are actually the abs sensors IIRC, which are of course on the hubs themselves & you have to actually also set the size of wheels on the car for brakes & its possible this also affects the speedo, only possible mind you but given abs seems to control a fair bit like speed sensing, braking systems & the tpms, it wouldnt be impossible for this to also be linked to what we're discussing here.
Question is what wheels were on originally, which I would guess a 17 inch & you now have 18 inch but no change in coding to the larger wheels, but on some cars there isnt an option to set 18inch, there seems to be a possible requirement to put a bridge in wiring on the abs controller to be able to set a larger wheel fitted, as I have tried the coding on mine, given I have the larger brakes & wheels & it wont accept my coding as yet, so I will be looking at the bridge method 1st then test coding again.
Will report back when I check it & for the record I have a mk60 abs controller, maybe with vagcom you can check abs coding & see if yours gives you an option for 18inch.
This may or may not be relevant but something to bare in mind huh.
