Don't want to rain on your parade, but I bought a 2008 1.18 TFSI manual S-Line with 45,000 two years ago and it was the most unreliable car I have ever owned. I was absolutely made up when I got the car but after a month of owning it both front wheel bearings went. I can't remember the exact cost but it was a few hundred pounds.
Then it failed an MOT due to a cracked rubber on a ball joint. That was replaced costing another couple of hundred pounds with labour. Then the car starting jerking during heavy acceleration. One night on the motorway the car went into limp mode. Scanned the car and diagnosed a faulty coil.
Replaced the coil and but the jerking kept getting worse. Took it to an VAG 'Specialist' in St Helens (The Volkswagen Centre - now branded Blackburns - avoid like the plague) who diagnosed a faulty throttle body. £500 later and after a month or so the jerkiness returned. A scan showed a flap position sensor motor in the intake manifold was at fault. Awesome GTI quoted me near £900 to replace the entire manifold. That was breaking point and I part exchanged the car. Total spend was around £1,000 in a year.
Having said that I've just bought another A4 so I must be stupid
