The Renault Clio II is an iconic versatile city car that marked a turning point for Renault in terms of comfort and road handling. Marketed in several phases (Phase 1: 1998-2001, Phase 2: 2001-2003, Phase 3: 2004-2005) and extended under the "Campus" designation until 2012 in Europe (and beyond in South America), it democratized direct diesel injection with the famous 1.5 dCi. While its dynamic qualities and comfort are undeniable, its reputation has been heavily tarnished by major reliability issues on the first generations of dCi engines (Delphi pump) and electronic quirks (UCH).
The Renault Clio II is a car with two faces. If you are looking for a diesel, avoid at all costs the 1.5 dCi produced between 2001 and 2005 unless the complete injection system (pump, injectors, tank) has been recently replaced with an invoice. Prioritize 'Campus' versions post-2006 where the dCi has been made more reliable, or opt for the rustic but indestructible 1.9D if performance is not a priority. Paradoxically, the petrol versions (1.2 and 1.4) are excellent choices, very reliable and economical, often preferable to diesel for this generation.
