Bentley Arnage MOT Reliability Overview
The Bentley Arnage is a relatively common sight on UK roads, with 27,842 MOT test results recorded in our database spanning 13 manufacture years. It has an overall MOT pass rate of 84.5% and a failure rate of 15.5%, which is well above the UK average of approximately 37%.
Based on this data, the Bentley Arnage earns a "Excellent" reliability rating. The average Bentley Arnage presents for MOT with approximately 51,267 miles on the clock. Manufacture year matters: 2010 models achieve the highest pass rate at 94.4%, while 1998 models have the lowest at 81.2%. This 13.2 percentage point difference suggests notable variation in build quality or component durability across production years.
The most common MOT failure for the Bentley Arnage is Brakes, affecting 12.7% 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 9.4%. Tyres rounds out the top three at 7.8%. 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 Bentley Arnage shows a moderate increase in MOT failures after warranty. The 26% increase is typical — plan for gradual maintenance cost increases. Peak failure occurs at age 12 (17.7% fail rate).
Note: pass rates may improve for very old vehicles due to survivorship bias — only well-maintained cars remain on the road.

About Bentley Arnage MOT Data
The Bentley Arnage is a relatively common sight on UK roads, with 27,842 MOT test results recorded in our database spanning 13 manufacture years. It has an overall MOT pass rate of 84.5% and a failure rate of 15.5%, which is well above the UK average of approximately 37%.
For Bentley Arnage owners, these results suggest a reliable vehicle that generally passes its MOT without major issues. 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 Arnage is likely to perform.
Brakes — 12.7% of failures
Brakes issues account for 12.7% of MOT failures on the Bentley Arnage. 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 — 9.4% of failures
Suspension issues account for 9.4% of MOT failures on the Bentley Arnage. 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.
Tyres — 7.8% of failures
Tyres issues account for 7.8% of MOT failures on the Bentley Arnage. 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.
