2008 BMW 635 3.0L Diesel · SR58 KTP

The vehicle is currently roadworthy, but the maintenance history reveals a reactive approach to repairs rather than proactive upkeep. The most recent test in July 2024 at 189,322 miles shows a pass only after a significant failure five days prior. This failure highlighted critical safety issues, including a fractured offside front coil spring and tyres with exposed cords and illegal tread depths. While the car passed the immediate re-test, the trend suggests that the owner only addresses mechanical faults when they reach the point of an MOT failure. At 189,322 miles over 18 years, the car has averaged approximately 10,500 miles per year, which is consistent with typical usage for a grand tourer. There is a notable gap in data between November 2021 and July 2023, where the vehicle covered roughly 9,600 miles. However, the accumulation of 12,000 miles between July 2023 and July 2024 indicates a period of recent heavy use. This high mileage places significant strain on the complex drivetrain and suspension components typical of this BMW era. A buyer must conduct a thorough inspection of the engine bay and underbody. The record notes persistent oil leaks onto the plastic undertrays since 2020, appearing again in 2024, suggesting a chronic gasket or seal failure that remains unaddressed. The suspension shows signs of ongoing wear, with misting shock absorbers noted in 2021 and 2023, and deteriorated anti-roll bar ball joint dust covers in 2023. Given the fractured coil spring in 2024, the entire front suspension geometry should be checked for bushing wear and further component fatigue. The braking system also requires scrutiny. Records from 2020 flagged pitted and scored brake discs on all corners along with deteriorated rear brake hoses. While these were not flagged in later tests, the age of the rubber components and the high mileage suggest these parts may be far beyond their design life. The buyer should verify the thickness of the brake pads and check for any cracking in the hydraulic lines, as the history indicates a pattern of neglecting wear items until they become hazardous.
