We have not found this engine singled out by any emissions scandal, but it is an old design with several critical maintenance items - timing belt, water pump, turbo and EGR: check the service history before buying.[2][3][4]
Faults that affect 2005 cars
- High severityFrequency: OccasionalTimingTiming belt and water pumpThe 1.4 TDI drives its timing with a toothed belt; on the unit-injector generation, that belt and its camshaft also drive the unit injector pumps. It is advisable to change the water pump along with the kit: if it seizes first, it can drag the belt with it, risking breakage and serious damage.Repair (garage): €400–€700
- High severityFrequency: OccasionalTurboFailing turbo: loss of power, whistling or smokeThe 1.4 TDI turbo can seize through carbon build-up or wear on the shaft over time. The engine loses power, whistles or gives off bluish smoke, and replacing it costs around €1,000 if there is no added damage to other parts.Repair (garage): €1,000
- Medium severityFrequency: CommonEmissions controlEGR valve clogged with carbonThe EGR valve builds up carbon, especially on short urban trips, until it seizes and stops sealing or opening precisely. The engine loses power and jerks; cleaning it costs considerably less than replacing it.Repair (garage): €100–€1,000
Faults outside the engine in the 2005 Audi A2
- Critical severityFrequency: OccasionalAirbags and safetyDriver's airbag that may not deploy with the three-spoke sports steering wheelIn 2002 the DVSA recorded an Audi campaign because, in A2s with the three-spoke sports steering wheel within certain chassis ranges, the driver's airbag might not deploy in a collision above the trigger threshold. The remedy is to replace the airbag unit.
- Medium severityFrequency: OccasionalBrakesLoss of parking brake strength (handbrake)German press points to the A2's handbrake as a weak point: it was already among its defects in 2004, and in 2018 it was explained that the parking brake, like the service brake, pulls with less force as it ages. No source gives figures or mentions a campaign.
- Low severityFrequency: OccasionalElectrical systemElectric window regulator failureA used-car test in the German press (2004) lists faulty electric window regulators among the A2's weak points and describes them as a common problem across several brands in the group. The source does not say which part fails, at what mileage or how often.
