Volkswagen Polo Mk6 (AW)

The sixth-generation Volkswagen Polo (AW), launched in 2017, represented a major leap forward for the supermini, growing significantly in size to match the dimensions of an older Golf. Built on the MQB-A0 platform, it offered a level of refinement, safety technology, and "big car" feel that established it as a segment leader in the UK used market. Positioned as a more premium alternative to the Ford Fiesta and Vauxhall Corsa, it remains a favorite for its strong residual values and understated, high-quality interior. Reliability is generally very high, with the Mk6 Polo consistently scoring well in UK owner satisfaction surveys. The 1.0-litre TSI three-cylinder petrol engines are mechanically robust, though occasional misfires can occur due to failing ignition coils. The optional 7-speed DSG automatic transmission requires strict 40,000-mile fluid changes to prevent mechatronic unit failure, and some owners have reported frustrating software glitches with the infotainment system and faulty door lock actuators. Mechanically, the Polo is sound, but like its MQB-platform siblings, it can suffer from slow-leaking water pump housings over time. When buying a used AW Polo in the UK, the 1.0 TSI (95PS or 115PS) is the recommended "all-rounder" for its balance of efficiency and performance. Prospective owners should test the central locking and remote fob multiple times to ensure the actuators are functioning correctly and check the service history for recent DSG maintenance if buying an automatic. A 2021-onwards facelift model is particularly desirable, as it introduced LED headlights as standard and updated interior technology. A full VW or specialist history is a major plus, ensuring any critical software recalls have been addressed.
