Recalls & safety

Pros & cons

Pros

  • Sporty, planted handling; available quattro and a 250-hp 3.2 V6 on early cars.
  • Premium feel and build quality unusual for a compact hatch of its era.
  • Practical Sportback body with a genuinely useful hatch.
  • Inexpensive to buy used today.

Cons

  • Premium fuel and pricey German maintenance.
  • 2.0 TFSI carbon buildup and oil consumption need attention.
  • Takata airbag recall affects most years, confirm it was done.
  • The S tronic / DSG dual-clutch automatic is the defining weak point, harsh shifting and costly mechatronic failures, worst on 2006 and 2009-2010 cars.

Move your cursor along the line to see the estimated value for any year.

Curve anchored at the entry-trim base MSRP ($26,920). Higher trims started higher (up to $36,975), and options added more.

The curve's data ends 10 years in, so the line levels off after that. Treat the tail as a floor, not a forecast: asking prices for older cars depend mostly on condition, mileage, and the current market, and often sit well above it.
