2008 BMW 635 3.0L Diesel · S33 AAK

The roadworthiness status of this BMW is currently questionable, as the most recent test on August 26, 2023, at 138,730 miles sits nearly three years behind the current date. Operating without a valid annual test for this duration leaves a significant compliance gap, and buyers must verify the current MOT status before purchase. Despite this long lapse, the final recorded test ended in a clean pass with zero defects noted, indicating that previous mechanical concerns had been resolved. The vehicle has accumulated 138,730 miles over its 18-year lifespan, averaging a modest 7,707 miles per year, which aligns with typical usage for a grand tourer of this class. The historical mileage progression reveals steady accumulation punctuated by irregular test intervals. Just 361 miles separated the January 19, 2022 pass at 130,241 miles from the September 12, 2022 failure at 130,600 miles. The subsequent pass occurred the very next day on September 13, 2022, followed by another test exactly 51 days later on August 26, 2023, where mileage rose by 8,129 miles over nearly a full year. Inspection of the mechanical and structural integrity requires a thorough physical examination due to the absence of recent test data. The sparse advisory history across these examinations suggests basic components were monitored, but high-mileage BMW E63 models frequently suffer from degraded suspension bushes, oil leaks from the engine gaskets, and corroded brake lines or subframes. Prospective buyers should inspect the condition of the brake discs and pads, check for suspension knocks during a road test, and verify that all electronic modules function correctly given the age of the vehicle.
