The second-generation Toyota Auris (E180) marks a stylistic and dynamic break from its predecessor. Lower, sharper, and with a better-finished interior, it was designed to reclaim the European compact car market (C-segment). Facelifted in 2015 (phase 2), its engine lineup evolved significantly. Although the hybrid version (HSD) accounted for the majority of sales, the Auris offered a full range of diesel engines to meet the demands of European high-mileage drivers of the time. It features historical Toyota blocks (1.4 and 2.0 D-4D) as well as a BMW-sourced block (1.6 D-4D) introduced during the facelift. Overall, the Auris II is a benchmark for reliability, although diesel versions require more rigorous monitoring than petrol or hybrid variants.
The Toyota Auris II is a highly recommendable purchase, often considered one of the most reliable compact cars of its decade. Regarding diesels (your target): the choice should be dictated by your usage. The 1.4 D-4D is an excellent economical and robust choice for mixed journeys. The 2.0 D-4D (2012-2015) is the best compromise for high-mileage drivers, having corrected the early defects of the previous generation. However, caution is advised with the 1.6 D-4D (2015-2018): although pleasant, its BMW origins (N47) bring risks of timing chain and EGR valve issues that clash with Toyota's usual peace of mind. If you drive less than 20,000 km/year or mostly in the city, abandon diesel and confidently opt for the excellent Hybrid version (1.8 HSD).
