Renault Master Lm35 MOT Reliability Overview

The Renault Master Lm35 is a niche vehicle in the UK, with 3,722 MOT test results recorded in our database spanning 5 manufacture years. It has an overall MOT pass rate of 55.0% and a failure rate of 45.0%, which is below the UK average of approximately 37%.

Based on this data, the Renault Master Lm35 earns a "Poor" reliability rating. The average Renault Master Lm35 presents for MOT with approximately 126,946 miles on the clock. Manufacture year matters: 2008 models achieve the highest pass rate at 84.8%, while 2001 models have the lowest at 49.4%. This 35.4 percentage point difference suggests notable variation in build quality or component durability across production years.

The most common MOT failure for the Renault Master Lm35 is Brakes, affecting 55.1% of all tests. 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. The second most common issue is Suspension at 37.0%. Lamps, Reflectors and Electrical Equipment rounds out the top three at 32.6%. Together, these top 3 failure categories account for a significant portion of all MOT failures for this model.

💡 What does the warranty cliff mean?

The Renault Master Lm35 shows a relatively stable failure rate after warranty — the change of 0% is negligible. Peak failure occurs at age 16 (54.5% fail rate).

Note: pass rates may improve for very old vehicles due to survivorship bias — only well-maintained cars remain on the road.

About Renault Master Lm35 MOT Data

The Renault Master Lm35 is a niche vehicle in the UK, with 3,722 MOT test results recorded in our database spanning 5 manufacture years. It has an overall MOT pass rate of 55.0% and a failure rate of 45.0%, which is below the UK average of approximately 37%.

For Renault Master Lm35 owners, these results suggest above-average failure risk — thorough pre-MOT checks are recommended. Focus your pre-MOT checks on brakes and suspension for the best chance of a first-time pass. Use our detailed year-by-year breakdown and failure analysis below to understand how your specific Master Lm35 is likely to perform.

Brakes — 55.1% of failures

Brakes issues account for 55.1% of MOT failures on the Renault Master Lm35. 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).

Suspension — 37.0% of failures

Suspension issues account for 37.0% of MOT failures on the Renault Master Lm35. 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.

Lamps, Reflectors and Electrical Equipment — 32.6% of failures

Lamps, Reflectors and Electrical Equipment issues account for 32.6% of MOT failures on the Renault Master Lm35. 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.
