The 1985 Renault R11 has an MOT pass rate of 49.2% based on 191 tests — significantly below the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 70,581 miles on the odometer. With a 50.8% failure rate, the 1985 R11 is rated as "Very Poor" for MOT reliability.
The leading cause of MOT failure for the 1985 Renault R11 is Body, chassis, structure, responsible for 2.1% of failures. 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 range from £100–500+. Noise, emissions and leaks is the second most common issue at 2.1%. Tyres follows at 1.0%.

About This Data
The 1985 Renault R11 has an MOT pass rate of 49.2% based on 191 tests — significantly below the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 70,581 miles on the odometer. With a 50.8% failure rate, the 1985 R11 is rated as "Very Poor" for MOT reliability.
If you own or are considering buying a 1985 Renault R11, 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. At 70,581 average miles, these vehicles are in the mid-range where component wear starts to become a factor.
Body, chassis, structure — 2.1% of failures
Body, chassis, structure issues account for 2.1% of MOT failures on 1985 Renault R11 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.
Noise, emissions and leaks — 2.1% of failures
Noise, emissions and leaks issues account for 2.1% of MOT failures on 1985 Renault R11 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.
Tyres — 1.0% of failures
Tyres issues account for 1.0% of MOT failures on 1985 Renault R11 models. Tyre failures include tread depth below the legal minimum of 1.6mm, cuts, bulges, exposed cords, and incorrect tyre pressure. Tyres are one of the most common and easiest-to-prevent MOT failures. Typical repair costs: £50–200 per tyre. Pre-MOT check: Check tread depth with a 20p coin — if the outer band is visible, the tyre is too worn. Look for bulges, cuts, or embedded objects. Ensure all tyres match the recommended size and load rating.
