About This Data
The 1992 Renault R21 has an MOT pass rate of 47.3% based on 351 tests — significantly below the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 110,595 miles on the odometer. With a 52.7% failure rate, the 1992 R21 is rated as "Very Poor" for MOT reliability.
If you own or are considering buying a 1992 Renault R21, be prepared for above-average maintenance costs. Before your MOT, pay particular attention to body, chassis, structure: Inspect sills, wheel arches, door bottoms, and the chassis for rust. Surface rust is acceptable but structural corrosion or holes will fail. Check that all doors, bonnet, and boot close securely. With an average mileage of 110,595 miles, these vehicles are in the higher-mileage bracket where wear-related failures become more common.
Body, chassis, structure — 3.4% of failures
Body, chassis, structure issues account for 3.4% of MOT failures on 1992 Renault R21 models. Body and structure failures include excessive corrosion, sharp edges, loose panels, and damage to the vehicle frame. Rust is the primary concern, especially on older vehicles or those exposed to road salt. Typical repair costs: £100–500+. Pre-MOT check: Inspect sills, wheel arches, door bottoms, and the chassis for rust. Surface rust is acceptable but structural corrosion or holes will fail. Check that all doors, bonnet, and boot close securely.
Suspension — 2.8% of failures
Suspension issues account for 2.8% of MOT failures on 1992 Renault R21 models. Suspension failures typically involve worn bushes, leaking shock absorbers, broken coil springs, and damaged suspension arms. These affect ride quality, tyre wear, and road holding. Typical repair costs: £200–500. Pre-MOT check: Look for uneven tyre wear, listen for clunking over bumps, and check if the car pulls to one side. A bouncy ride suggests worn shock absorbers. Visually inspect coil springs for cracks.
Noise, emissions and leaks — 2.3% of failures
Noise, emissions and leaks issues account for 2.3% of MOT failures on 1992 Renault R21 models. Emissions failures occur when exhaust gases exceed legal limits for carbon monoxide (CO), hydrocarbons (HC), or particulate matter (diesel). Common causes include faulty oxygen sensors, clogged catalytic converters, or DPF issues on diesel vehicles. Typical repair costs: £100–1,000+. Pre-MOT check: If the engine management light is on, get it diagnosed before the MOT. For diesel cars, ensure the DPF has completed a regeneration cycle. Regular servicing and using premium fuel before the test can help.
