  2011 & 2010 Audi A3. Click image to enlarge |
The TDI engine seems to be largely free of troublesome issues, though a possible intercooler issue may cause icing that could choke the engine’s air supply and cause stalling in cold weather. This was addressed by a service bulletin, as were minor issues with injectors and fuel pumps, in other TDI applications. Ask your local Audi dealer to be sure no recall or Technical Service Bulletin (TSB) work is outstanding on the A3 TDI you’re considering.

The Verdict: Stick with a 2.0T manual model where possible for lower purchase prices, higher availability and lower running costs. A TDI will prove better on fuel, but more expensive to buy and harder to find. The V6 engine will cost the most to fuel and maintain in the long run.
Buying from a certified pre-owned program at an Audi dealer is likely the safest bet – but be positive to have a mechanic confirm that the model you’re considering isn’t suffering from the well-documented carbon buildup issues. This may require removal of the intake manifold for a visual inspection, or a compression test.
