Hope you enjoy your GTI Mossy. Had my Mk8 from new back in Nov 2020. Did have an initial period of tech problems which took altogether two months to sort out in its first year. That apart and with a few Racing Line additions {alloys, air intake system and some cosmetic bits} its been fine. There are some pics posted in Nov 23 within the forum pages somewhere!
Pop to the shops no dramas, reset the driving modes, drive it accordingly and it will revive that hot hatch spirit buried inside.
The Mk8 has had a tough time, due in no part to incompetence at VW which cost the then CEO his job, but I've enjoyed mine tbh.
Have fun!
