Always wanted one now feel like I made a mistake or rushed into it

Hi people I just bought a 1.8T 180 last night test drive fine on B roads nothing where I could really open it up but on the way home on the motorway it judders when at high end acceleration and this morning hard driving caused it to over heat but when I took cap off it cool down and not seen issue since but also not drove it hard. Have a bought a piece of crap or am I over thinking it. Also couldn’t see faults due to dash being pixelated and not working properly but sure there was an error saying coolant issue Please help Thanks Geraint
