Common initial failure categories
These are the items that most often caused a Bentley Arnage to fail its first test, with what each one usually means for a buyer.
- Brake Performance — 2.7% of tests. The brakes underperformed on the rolling road. Expect brake work rather than an adjustment.
- Exhaust Emissions — 2.1% of tests. The car exceeded its emissions limits. Can be a sensor or a service, but on a diesel it can also mean an expensive filter or catalyst.
- Anti-roll Bars — 1.8% of tests. Worn anti-roll bar links or bushes. Inexpensive but often recurring.
- Suspension Arms — 1.6% of tests. Worn arms or bushes. A common age-related repair that affects handling and tyre wear.
- Condition — 1.6% of tests. Corrosion, damage or wear on a tested component. Worth seeing in person, as the cost ranges from trivial to structural.
- Wipers — 1.5% of tests. Worn wiper blades. Minutes to fix, and a fair hint that servicing was skipped.
What this does and does not tell you
A pass rate describes how a population of cars behaved on test day. It says nothing about how one car was driven, serviced or repaired, and an MOT does not cover the engine, clutch or gearbox at all.
Use it to know what to look for: if tyres and brakes dominate the list, price those in; if corrosion or suspension appears, get underneath the car. Then check the individual vehicle — its MOT history shows whether these same items have been advised year after year, and its mileage record shows whether the reading is consistent.
How many Bentley Arnage are left?

- Suspension Arms — 1.6% of tests in 2024. Worn arms or bushes. A common age-related repair that affects handling and tyre wear.
- Ask why it was off the road — Of the 1,757 Arnage vehicles still on the DVLA record, 1 in 2 is SORN (761 at 2026 Q1). A car that has been laid up needs a closer look at brakes, tyres and the MOT history.
- Budget for a shrinking fleet — Licensed numbers are down 44% from the 2014 Q3 peak of 1,781. Fewer cars on the road usually means fewer donor parts and fewer specialists.
