The Renault Mégane II marked its era with its bold design (the famous abrupt tailgate) and technological innovations for its category (hands-free starting card, panoramic roof). Voted Car of the Year 2003, it was also the first compact car to achieve 5 stars in the Euro NCAP crash test. However, its reliability record is split into two distinct eras. Phase 1 (2002-2005) suffered from serious early issues, both electronically (cards, sensors, power windows) and mechanically (turbo failures on dCi engines, Delphi injection pumps). Phase 2 (from January 2006) benefited from a major overhaul of its components, becoming a thoroughly recommendable car. Today, it is a very affordable used model, but one that requires rigorous selection of the engine and production year.
The Renault Mégane II is a textbook example of a car with two faces. Phase 1 models (2002-2005), particularly the 1.5 dCi 80/100 and 1.9 dCi 120 diesels, are to be absolutely avoided due to major design flaws (turbos, injection pumps, electronics). In contrast, a Mégane II Phase 2 (2006-2009) is an excellent used car deal. The petrol engines (1.6 16v, 2.0 16v) are very robust, and the chain-driven 2.0 dCi is one of the best diesels of its generation. Buy a Phase 2 with a clear service history, check the onboard electronics, and you will get a comfortable, safe, and economical compact car.
