Peugeot 806 MOT Reliability Overview
The Peugeot 806 is a relatively common sight on UK roads, with 38,701 MOT test results recorded in our database spanning 11 manufacture years. It has an overall MOT pass rate of 46.3% and a failure rate of 53.7%, which is significantly below the UK average of approximately 37%.
Based on this data, the Peugeot 806 earns a "Very Poor" reliability rating. The average Peugeot 806 presents for MOT with approximately 127,009 miles on the clock. Manufacture year matters: 1971 models achieve the highest pass rate at 55.1%, while 2004 models have the lowest at 40.0%. This 15.1 percentage point difference suggests notable variation in build quality or component durability across production years.
The most common MOT failure for the Peugeot 806 is Suspension, affecting 42.9% of all tests. 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. The second most common issue is Lamps, Reflectors and Electrical Equipment at 39.3%. Brakes rounds out the top three at 36.9%. 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 Peugeot 806 shows a relatively stable failure rate after warranty — the change of 0% is negligible. Peak failure occurs at age 16 (58.8% fail rate).
Note: pass rates may improve for very old vehicles due to survivorship bias — only well-maintained cars remain on the road.

About Peugeot 806 MOT Data
The Peugeot 806 is a relatively common sight on UK roads, with 38,701 MOT test results recorded in our database spanning 11 manufacture years. It has an overall MOT pass rate of 46.3% and a failure rate of 53.7%, which is significantly below the UK average of approximately 37%.
For Peugeot 806 owners, these results suggest above-average failure risk — thorough pre-MOT checks are recommended. Focus your pre-MOT checks on suspension and lamps, reflectors and electrical equipment 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 806 is likely to perform.
Suspension — 42.9% of failures
Suspension issues account for 42.9% of MOT failures on the Peugeot 806. 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 — 39.3% of failures
Lamps, Reflectors and Electrical Equipment issues account for 39.3% of MOT failures on the Peugeot 806. 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.
Brakes — 36.9% of failures
Brakes issues account for 36.9% of MOT failures on the Peugeot 806. 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).
