They really are that bad. Just run away.
I had a 2004 VW Beetle TDI that my aunt gave me, it was meticulously maintained.
Total money pit. Was on its 3rd Dual Mass Flywheel and it STILL chattered like crazy! Cost almost $2000 for the first one, second one replaced under warranty, transmission was failing too. It literally CRUNCHED when you let off the gas when it was cold. And when I say crunch, I mean CRUNCH. CV boots tearing all the time, door panels breaking, $300 in speakers dying and I replaced (2 of them), camshaft worn out, timing belt engines, A/C compressor very loud and going out, blower motor very loud, headlights burn out all the time, air bag light came on, luckily it was able to be reset set by a shop because otherwise the upholstery on the seat would have had to have been removed to replace the sensor, airbag light came on before for multiple other sensors, check engine lights, the last one for the turbo actuator sensor. It cleared itself luckily, otherwise the whole turbo has to be replaced. Volume knob going out on the stereo deck, $1000 for new radio, I tried a nice aftermarket one but it sounded weird. New door panels are literally $1000 a PIECE, used ones are impossible to come by because they break so easy and fade and get all gummy from heat. I glued and riveted the old ones back together. And I'm talking a tube of glue and 12 rivets per door panel. Seats didn't like to fold forward anymore most of the time, sunroof sometimes got stuck, windows sometimes wouldn't go up and would roll themselves back down, starter died at low mileage and so did the alternator.
I could go on and on. Endless money pit cars, I'd never own a German anything unless it was a really old BMW or Merceded diesel. Even then it's really pushing it.
My aunt's 2013 VW Beetle TDI isn't any better so far either.
