Renault Clio RS
High-revving 2.0-litre — naturally aspirated in the Clio RS III (screams to 7,500 rpm like a small touring car engine), twin-scroll turbo in the Megane RS making 165-201 hp. The NA version rewards every rev, the turbo pulls hard and early. Cam adjuster and timing belt are the big service items — always do both together at 120,000 km / 6 years. The VVT oil strainer gunks up with lazy oil changes — 10,000 km max intervals. Let the turbo cool down after track sessions.
Last Pure Naturally Aspirated RS — an Icon
7,500 rpm, no turbo lag, no artificial soundtrack. The F4R in the Clio RS III sings at high revs like a small race engine and smells of hot metal when pushed. The steering is so direct that road cracks can be felt through the palms. Light, agile, without digital filters between driver and road. Anyone who has driven one properly understands why the RS community celebrates it as a generational car.
Engine Weaknesses 6
The highly tuned F4R-RS in the Megane RS is frequently driven hard. Insufficient cool-down periods after full-load operation damage the turbo bearings. Recommended: 2–3 minutes idle before switching off after spirited driving.
Symptoms: Whistling from turbo area, oil in intercooler
The timing belt change on the F4R-RS requires full removal of intake manifold and ignition coils. Workshop costs 530–880 € at independents, up to 1,600 € at Renault dealers. Always replace water pump at the same time. Interval: 120,000 km or 6 years.
Symptoms: No warning before failure — check service book for documented replacement
Sportily driven Megane RS with F4R-RS develop oil leaks at valve cover, turbo oil feed lines and crankshaft seals, accelerated by high loads and temperatures.
Symptoms: Oil traces under engine, dropping oil level, oil smell in cabin
As with the standard F4Rt, hot restart problems occur on the RS after intensive driving and subsequent shutdown, caused by fuel pressure drop. The hot engine bay vaporises fuel in the lines.
Symptoms: Poor warm restart, extended cranking, engine then runs normally
The Megane RS is often driven on track. The standard clutch wears significantly faster than in normal road use. Many used examples already have performance clutch upgrades.
Symptoms: Clutch slip under acceleration, spongy clutch feel, burning smell
The oil strainer of the inlet camshaft VVT adjuster clogs up with deposits from extended oil change intervals. Result: poor cold-start performance, rattling and in the worst case valve damage. Repair costs 400–1,200 €.
Symptoms: Rattling on cold start (diesel-like sound at front), poor part-throttle performance, difficult hot start
Vehicle Weaknesses 7
Shock absorber failures are regularly identified at vehicle inspections. The Clio III generation has the most suspension problems. Sway bar links wear out early.
Rust problems are known on the Clio III, particularly on wheel arches and sills. TÜV reports cite lighting failures and rust as frequent issues driving up maintenance costs.
Brakes on the Clio III can be worn out as early as 50,000 km. Brake discs and pads wear faster than average, requiring regular inspection.
The Clio III is particularly frequently flagged at the MOT for broken springs and worn shock absorbers. Repair costs are 250–500 € per axle. Tie rod ends and strut top mounts are also typical MOT defects.
Ignition coil failures are a known weak point in the Clio III as well, particularly on the 1.2 and 1.4 petrol engines. Misfiring and cylinder dropouts in everyday driving are typical consequences.
Wiper motors, radio systems and airbag sensors fail more frequently. Electrical problems are widespread on the Clio III and are often caused by corroded connectors.
Headlights, rear lights and fog lights fail significantly more often than the class average. TÜV reports confirm below-average lighting reliability.
Reports & Tests
Shock absorbers, springs and steering joints are flagged above average. Rust susceptibility is particularly serious. Brake lines and brake discs wear prematurely.
