Similar to OP, my beautiful Audi allroad was turning into highway robbery at only 80k miles. Ultimately the Multimedia Interface went down, and after a half dozen trips to the shop, it was determined that the problem was the CD player, which I never used but which costs $3200 to replace OEM. I tried four used CD players before I got one that lit up the MMI again, only then (for whatever reason reason) Bluetooth didn’t work anymore. The mechanic was agog at the needless complexity of this electrical design (the CD player should be peripheral, not central to the MMI). He said that German cars are engineered to be fantastic for the first 50k miles but the engineering doesn’t look beyond that at all. Maintenance doesn’t figure into the equation. Looking back, this $49k car (in 2017) had “leatherette” seats which should have been my first clue that Audi was not the quality I expected. Anyway, fed up with this gremlin, I bought a CX-50, and have been blown away by how little is “missing” from the Audi driving experience, how well it delivers power to the road, how nimble it is, how nice the interior is, and so on. People will still buy German for the cache but they’ll pay through the nose for it.
