2006 Bentley Arnage 6.8L Petrol · BL06 DAB

A failed test on 29 May 2026 marks a clear deterioration in this Arnage's record after three consecutive clean passes in 2022, 2023 and 2025: the car was failed for a supplementary restraint system warning lamp indicating an airbag fault and, more seriously, a defective or ineffective brake servo. The brake servo failure is the defining concern, as it directly affects stopping assistance on a heavy, powerful luxury saloon, and it must be rectified and retested before the car can be considered roadworthy. Prior to this, the record shows a recurring pattern of front suspension and tyre-related items rather than structural or corrosion failures: a severely deteriorated nearside front ball joint dust cover appeared in both 2020 and 2021, a power steering ram seepage was noted in 2021, and tyre wear or under-inflation was flagged in 2020, 2021 and 2024, alongside corroded rear suspension pipes advised in 2024. At roughly 3,690 miles per year over two decades, the 73,807 recorded miles reflect light annual use consistent with a car that has spent significant periods standing. Test intervals have been regular with no multi-year gaps, so there is no evidence of extended off-road storage in the record, but low-mileage use on a complex 2006 Bentley still carries implications: hydraulic and pneumatic components, seals and brake system parts age with time as much as with distance, which is consistent with the servo failure, the steering ram seepage and the deteriorating rubber dust covers seen across the history. The repeated windscreen stone chip entries from 2020 through 2024 suggest the same screen has carried minor damage for years without replacement. The immediate priority for any buyer is verification that the May 2026 failure items have been properly repaired. The brake servo defect should be confirmed rectified with evidence of the work, and on a test drive the pedal should feel firm and assisted from the first application, with no excessive pedal effort, hissing from the servo unit, or a hard pedal after the engine has been switched off and restarted. The airbag warning lamp must remain extinguished through the full ignition cycle; an illuminated or flashing lamp after claimed repairs would indicate the fault persists, and SRS diagnosis on this era of Bentley can be costly. Beyond the failure items, the test drive should focus on the recurring front-end themes. Listen and feel for knocks or play from the nearside front suspension over uneven surfaces, given the repeated ball joint dust cover deterioration, and check for uneven front tyre wear consistent with the inner-edge wear previously recorded, which may point to geometry or worn linkage issues. Inspect the power steering ram area for fresh fluid seepage and check for any heaviness or noise at full lock. Finally, examine the rear suspension pipes for the corrosion advised in 2024 to establish whether it has progressed, and confirm the windscreen, door mirrors and headlight washers noted in earlier tests are in acceptable condition.
