A little update for others who may wonder the same; I’ve gotten it confirmed from the Audi dealer/importer here in Norway that my manual ‘13 A3 with the 1.4 TFSI CMBA engine does in fact not have a DMF but single mass.
Ill be ordering a sachs clutch kit and swapping it out myself, seeing as the kit itself is only 220£ and I’ve been quoted from 1700 to 2500£ for just a clutch swap, which is insane in my opinion.
