If you own or are considering buying a 1984 Renault R9, you can expect reliable MOT performance overall. Before your MOT, pay particular attention to brakes: Listen for squealing or grinding noises. Check brake pedal feel — if it feels spongy or goes to the floor, have the system inspected immediately. Look at brake pad thickness through the wheel spokes (minimum 3mm). With relatively low average mileage of 41,377 miles, many of these vehicles are still in good mechanical condition.
Brakes — 10.9% of failures
Brakes issues account for 10.9% of MOT failures on 1984 Renault R9 models. Brake-related failures include worn brake pads, corroded brake discs, leaking brake lines, and faulty brake servos. These are safety-critical components — any brake deficiency will result in an MOT fail. Typical repair costs: £150–400. Pre-MOT check: Listen for squealing or grinding noises. Check brake pedal feel — if it feels spongy or goes to the floor, have the system inspected immediately. Look at brake pad thickness through the wheel spokes (minimum 3mm).
Lamps, reflectors and electrical equipment — 8.7% of failures
Lamps, reflectors and electrical equipment issues account for 8.7% of MOT failures on 1984 Renault R9 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.
Visibility — 2.2% of failures
Visibility issues account for 2.2% of MOT failures on 1984 Renault R9 models. Visibility failures relate to the windscreen, wipers, washers, mirrors, and view-obstructing damage. Cracks in the windscreen swept area, ineffective wipers, or empty washer bottles are common causes. Typical repair costs: £10–300. Pre-MOT check: Check the windscreen for chips and cracks — damage larger than 10mm in the driver's swept area or 40mm elsewhere will fail. Test washers and wipers. Ensure both door mirrors are intact and adjustable.
