Renault Wind
The K4M in the Twingo RS — 1.6 litres, 16 valves, 133 hp — is a naturally aspirated engine with an honest character: it needs revs, but rewards every blip above 5,000 rpm with a rev-happy sound that turbocharged cars cannot reproduce. In the 980 kg Twingo RS it feels stronger than the numbers suggest. Timing belt every 120,000 km or 6 years — water pump always at the same time. Camshaft adjuster wears with excessive oil change intervals. Control arm rubber bushings are a known weak spot on the RS front axle.
Roadster charm
133 hp naturally aspirated in the lightweight Wind — 0–100 in 9.2 s, 201 km/h, open-air driving on the Twingo platform. Rare and likeable.
Engine Weaknesses 8
The K4M uses a timing belt that can break if the change interval (every 5 years or 120,000 km) is exceeded. In the 16V interference engine design a belt failure inevitably causes valve damage and total cylinder head destruction.
Symptoms: Sudden engine stop, no restart possible, compression failure
The K4M engine in the Twingo RS has limited engine bay clearance, making the timing belt change labour-intensive. Independent garages from €460, Renault dealers up to €1,100. Always replace the water pump at the same time. Interval: 120,000 km or 6 years.
Symptoms: No warning before belt failure — check service history for documented replacement
The variable valve timing (VVT) on the K4M 782 and similar variants is prone to malfunctions. The actuator wears and causes rattling and power loss, particularly on a warm engine between 1,500 and 4,000 rpm.
Symptoms: Sewing-machine-like rattling on a warm engine, power loss, camshaft control fault code
The original Sagem ignition coils are considered the biggest weakness of all Renault K-series engines of the era. Faulty coils cause misfires, rough running and intermittent engine failures, especially in damp conditions and at higher temperatures.
Symptoms: Engine misfires, cylinder dropout, engine warning light illuminates, possible pre-ignition
The front control arm rubber bushings on the Twingo RS II wear out by design very early — from as little as 12,000–25,000 km. The rubber gaiter rubs against the arm and wheel carrier, becomes porous, and water enters the joint. Renault improved the replacement parts with a protective ring in 2013.
Symptoms: Pulling when braking, knocking from the front, unstable straight-line tracking, noticeable play when shaking the front wheel
The camshaft phaser on the K4M wears with excessively long oil change intervals or poor-quality oil. Typical: brief cold-start rattle that disappears once the engine reaches operating temperature. Repair costs around €350–850; combine with timing belt replacement.
Symptoms: Rattling for 3–5 seconds on cold start (especially below 0°C), engine then runs normally; increased consumption if the phaser runs permanently open
At higher mileages the K4M is prone to oil leaks from the cylinder head cover gasket and camshaft seals. Leaking oil can drip onto hot exhaust components and cause smoking.
Symptoms: Oil smell in the engine bay, visible oil traces on the cylinder head, smoke formation
The throttle body of the K4M carbonises from crankcase ventilation oil mist. Deposits cause rough idle and intermittent stalling. Renault has officially acknowledged this as a known issue.
Symptoms: Rough idle, engine stalls at low revs, hesitation on pull-away
Vehicle Weaknesses 7
The folding mechanism of the hardtop roof fails due to defective microswitches or hydraulic leaks. The roof can no longer fully open or close; repair requires special tools.
Window regulator motors fail and can often be traced back to a defective battery terminal or corrosion on the wiring. Windows get stuck or move jerkily.
On the Wind I, water enters through leaking roof and boot seals. The seatbelt roller and boot are often affected. The cause is difficult to locate as no leak is often detectable during targeted tests.
The microswitches in the electric folding roof mechanism of the Wind I fail frequently. The roof then no longer opens or closes, and the warning 'check roof' appears. Only emergency opening with a screwdriver remains possible.

Despite its sporty positioning, the Wind's interior uses budget plastics that show scratches and wear quickly.
