Maybe I've missed it in the discussion, but you've decided on a specific vag engine that you want, but don't know what car to get?
Essentially I'm struggling dropping from an 05 1.8T and 06 2.0 down to the 1.5T / 1.4T engines. I've driven two now, and although both have been nice cars (Golf, A3) the pickup, lag at roundabouts does have me concerned specifically with the Mrs driving as we're both used to being able to easily take off without issue.
Thing is, you rule out those engines, it's a massive proportion of them on the market, and most seem to be saying they're lemons because of the hesitation, and resultant fix VAG put out, then blamed on the 'characteristics' of the engine.
The second factor, outside of that, is just the frustration with the overcomplication of many out there. Happy with cruise, Aircon, that's it, don't want lane assists and all that messing around, I'm actually quite happy to have a manual handbrake, don't need radar cruise etc. Just more to go catastrophically wrong.
Like an earlier post mentioned, it's like they're intentionally designed have a limited use so everyone is on the PCP bandwagon constantly cycling through cars at cost because most will struggle to fix or maintain them anymore.
I'm actually starting to become concerned for many a traditional independent garage given the specialist kit, per manufacturer they're going to need to use too (e.g. timing kit for Audi belts etc)
Back on topic, went to see a 1.8T 15 plate Audi and it was battered, near 16k they wanted for it - brown coolant so the silica bag has already had it, terrible paintwork etc.
...there are a fair few 1.4-1.5T A3 and Golfs coming up, but they're all around the kangaroo fault time with 1-2 owners at most and sub 40k on the clock which keeps making me think people have tolerated it, had enough and shifted it through a trade in and took the hit.
