A lightweight pocket rocket weighing just over 1,000 kg with a rev-happy naturally aspirated 1.6-litre engine. The Twingo RS 133 shares its K4M engine and many chassis parts with the Clio RS 197, but in a smaller, lighter package. It offers excellent fuel economy for a hot hatch and a cult following among driving enthusiasts.
Simple, robust NA engine
Lightweight and fun to drive
Ball joints wear quickly
Scuttle panel water ingress
Buy if: You want a raw, lightweight hot hatch with low running costs and can find one with full service history and cambelt done.
Avoid if: You need comfort, refinement, or a car that tolerates neglected maintenance — the K4M engine needs its cambelt on time.

Common Problems
Ball joints wear quickly on pre-facelift models, causing vague steering and knocking · more· less
The lower ball joints on the Twingo RS are a well-known weak point, especially on pre-facelift (2008-2011) cars. Symptoms include a clunking noise over bumps and imprecise steering feel. Renault does not sell the ball joint separately — you must buy the complete lower wishbone arm at around €100-130 per side from Renault, or €40-60 for aftermarket. Aftermarket ball joints alone are available for around €20-40. Including labour, expect €200-500 for both sides. Some owners report needing multiple replacements within the car's life. This was partially improved on facelift models from 2012.
Variable valve timing pulley wears internally, causing diesel-like rattle at idle · more· less
The K4M engine uses a camshaft dephaser pulley for variable valve timing. As it wears, it produces a distinctive rattling noise at idle that sounds like a diesel engine, particularly when warm. This is a known K4M issue across Renault's range, not specific to the Twingo. The dephaser pulley itself costs around €100-150. Best practice is to replace it during the timing belt change to save on labour, bringing the combined cost to €400-700 at an independent specialist. If done separately, the labour alone adds €200-300 because the timing belt must be removed to access the pulley.
Upper gearbox mount under battery tray deteriorates, bolt can shear if ignored · more· less
The gearbox mount located under the battery tray wears prematurely, especially on cars used enthusiastically or on poor roads. Symptoms include noticeable vibration through the gearlever and a rocking motion under acceleration and braking. If left unchecked, the mounting bolt can shear, leaving the gearbox hanging on the subframe — a potentially dangerous failure. OEM replacement mount costs around €30-60, with fitting around €100-150 at an independent garage. Uprated mounts from Vibra-Technics or K-Tec Racing are available for around €80-120 and last significantly longer. Total repair cost including all engine/gearbox mounts is typically €150-400.
Standard exhaust rusts through, particularly the mid-section and back box · more· less
The standard mild steel exhaust on the Twingo RS is prone to corrosion, particularly in wet climates. The mid-section and rear silencer are most affected. Renault offered a stainless steel exhaust on the limited Silverstone GP edition, acknowledging the problem. A replacement OEM exhaust section costs €200-400. Aftermarket stainless steel systems from K-Tec or Scorpion range from €500 to over €1,000 but last indefinitely. Many owners fit an aftermarket system as a permanent solution when the original rusts through. Budget €300-800 depending on whether you opt for OEM replacement or stainless upgrade.
Water leaks through scuttle panel joint into the front footwells, damaging carpets and electrics · more· less
Water seeps through the join where the two-piece scuttle panel overlaps in the centre, pooling in the front footwells. If left unaddressed, this can lead to damp carpets, mould, and eventually corroded wiring or ECU damage. The fix is straightforward: lift the scuttle panel section, apply silicone sealant to the overlap joint, and tighten the securing screw. Also check and clear the drainage holes at each corner of the scuttle area below the wipers. The repair itself costs almost nothing in materials, but if water damage has already occurred, drying out carpets and replacing damaged wiring or connectors can cost €100-300.
Individual coil packs fail causing misfires, rough running, and loss of power · more· less
Coil pack failure is the most commonly reported cause of rough running on the Twingo RS 133. The engine uses individual coil-on-plug ignition, and when one fails the engine runs on three cylinders with noticeable vibration and reduced power. The good news is that replacement coils are inexpensive at around €25-35 each and are easy to fit — a straightforward DIY job requiring only basic tools. Even at a garage, replacing all four coils as a precaution costs only €100-150 including labour. This issue tends to occur more on higher-mileage cars above 80,000 km.
Steering rack develops play, causing imprecise steering and knocking over bumps · more· less
While not as common as on the Clio RS 197/200, steering rack failure does occur on some Twingo RS 133s, particularly those that have been driven hard or on rough roads. Symptoms include a clicking noise when turning and looseness in the steering. A new rack from Renault including fitting (4-5 hours labour) costs around €700-1,200. Inner tie rod ball joints wear separately and can be replaced individually for around €40-80 per side. An ex-Renault technician reported not encountering many steering rack replacements during their time, suggesting this is an uncommon but expensive fault.
Simple and mostly reliable, but age-related wear needs attention
The Twingo RS 133 is fundamentally a reliable car. The K4M engine is robust and proven across millions of Renault models, and the 5-speed manual gearbox is strong. Most issues are wear-related and typical of the car's age: ball joints, engine mounts, and exhaust corrosion. The dephaser pulley should be replaced with the timing belt as preventive maintenance. Water ingress through the scuttle panel is easy to fix if caught early. There are no catastrophic design flaws — most problems are well-understood and affordable to address.
Recalls and Technical Service Bulletins
Seat belt buckle retention failure (manufactured Sep-Oct 2014)
Verify completed
Bonnet skin separation due to adhesive failure (manufactured May 2014-Jul 2015)
Verify completed
The seat belt and bonnet recalls affect late-production Twingo II models and the Twingo III. Most RS 133 models (2008-2013) are unaffected. Contact Renault with the VIN to verify whether any applicable recalls have been completed.
Warranty Status
Factory warranty (2 years)
Expired on all Twingo RS 133 models
Rust perforation warranty (6 years)
Expired on all models
All Twingo RS 133 models are well outside their original 2-year factory warranty and 6-year rust perforation warranty. Extended warranty options from third-party providers may be available but are rarely cost-effective for a car of this age and value.
