Nope, not just neglected maintenance. The A4 cars with the 1.9L TDI (1999 - 2005 Jetta) were notorious for electrical problems. That isn't neglect.

I did maintenance by the VW service schedule with all OEM parts.

Things that broke on my 2003 Jetta Wagon (built in Germany BTW)
  1. The radiator fan
  2. The heater blower and resistor pack (twice)
  3. Glow plug harness (twice)
  4. MAF sensor
  5. Both headlights (The lenses yellowed)
  6. Replaced 3 out of 4 window regulators
  7. The sunroof seals started leaking
  8. I had to clean the intake manifold twice because soot from the EGR system would fill it up
  9. The glove box latch broke
  10. The center console latch broke
  11. The soft-touch paint stared peeling off the interior trim pieces

I had to do brakes, tires, shocks, struts, etc too but those are normal wear items.

Compare that to my 2005 Toyota Prius. The only thing I every had to replace on that car (and the 2009) that wasn't on the service schedule was the 3-way valve in the coolant system. The valve failed on both cars about 125K miles
