About This Data
The 2011 Mercedes R350 has an MOT pass rate of 76.1% based on 113 tests — well above the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 79,199 miles on the odometer. With a 23.9% failure rate, the 2011 R350 is rated as "Excellent" for MOT reliability.
If you own or are considering buying a 2011 Mercedes R350, you can expect reliable MOT performance overall. 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 79,199 average miles, these vehicles are in the mid-range where component wear starts to become a factor.
Body, chassis, structure — 1.8% of failures
Body, chassis, structure issues account for 1.8% of MOT failures on 2011 Mercedes R350 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.
Tyres — 1.8% of failures
Tyres issues account for 1.8% of MOT failures on 2011 Mercedes R350 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.
Lamps, reflectors and electrical equipment — 0.9% of failures
Lamps, reflectors and electrical equipment issues account for 0.9% of MOT failures on 2011 Mercedes R350 models. Lighting failures cover all external lights: headlights, tail lights, brake lights, indicators, fog lights, and reflectors. A single blown bulb will cause an MOT fail. This is one of the most preventable failure categories. Typical repair costs: £5–50. Pre-MOT check: Walk around the car and check every light — headlights (dipped and main beam), side lights, tail lights, brake lights, indicators, hazard lights, reverse light, rear fog light, and number plate lights. Replace any blown bulbs before the test.
