6'th update:
It's spring 2022. Have driven it a little less, because I bought electric scooter for everyday use. Still occasionally need my A2 for commuting and trips.
What have I done:
- Repaired windshield washer jets (needed inside cleaning)
- Repaired drainage plastic parts where rainwater flows from the hood, plastic was cracked. 2-component glue saved the day.
- Installed fake leather seat covers so original seats wont wear off and I can more freely put stuff onto seats. Easier to clean also.
- Repaired AC loop: changed AC compressor, changed AC reservoir, changed internal temperature sensor, repaired AC fan controller.
- Had AC loop filled and tested at local repair shop. It wasn't cheap, but overall now I have at least 1 car with working AC.
Known issues:
- some squeaks in the interior, not issue, but little annoying
- engine is more oliy then before. Oil seems to leak from turbo which will pain (and expensive) to repair.
Overall car still runs and drives great. I really like my A2, nice to drive and economical (especially important nowadays).
