The Renault Laguna I (codename B56 for the sedan, K56 for the Nevada wagon) succeeded the aging R21. It marked a spectacular leap forward for Renault in terms of manufacturing quality, suspension comfort, and ergonomics. A true road car, it went through two phases: Phase 1 (1993-1998) and Phase 2 (1998-2001), which brought smooth headlights, new taillights, improved passive safety, and new engines. While the gasoline versions proved very reliable, the diesel range (which is our focus) underwent a major technological transition, moving from atmospheric indirect injection (2.2 D) to high-pressure direct injection (1.9 dCi), with varying degrees of reliability.
The Renault Laguna I is now a 'youngtimer' or a very low-cost 'daily driver'. If you're looking for a diesel, the 2.2 dT is the most robust choice for towing or driving loaded, provided the timing belt has been done recently. The 1.9 dCi offers better driving pleasure but requires rigorous monitoring (EGR, turbo). The 1.9 dTi is to be avoided unless the accessory belt history is crystal clear. The atmospheric 2.2 D is indestructible but too slow for modern traffic. Paradoxically, the best deals on the Laguna I are found among the gasoline engines (1.8 and 2.0), which are indestructible and have fewer kilometers. The absolute black spot to check before purchase remains the heater core leak.
