Have you looked on the VWROC forum? there is a section 'Gremlins' the hassle people are having is pretty unbelievable, 123 pages and I think the most popular topic!!
I REALLY wanted another Golf R, my 7.5 has been faultless, I demo'd a 8R twice, the second time because I couldnt find the ESC button within the F STUPID and poorly thought out C*AP infotainment system.
Once set in either ESC sport or ESC OFF, press screen, press CAR, swipe CAR, Press BRAKES, select Normal/Sport/OFF confirm you really want to do it
(and you need to do it because the ESC ''help'' is now that intrusive and early to interfere) the car is quite the weapon, the new magna diff makes the car neutral/v slight O Steer instead of ploughing straight on.
And then the seats ***, look like something out of a 80's Fiesta, and the cheapness for eg: a bonnet prop, really? my lad used to take those off his Mk2 GTI Golfs and replace with struts
