1998 BMW 740 4.4L Petrol · S882 DHT

The most recent DVSA examination on 22 May 2026 recorded a PASS, although two advisories were noted: a nearside oil leak described as not excessive and slight free play detected in the steering box. Reviewing the recent trajectory, the maintenance trend is broadly stable but with a clearly worsening pattern of corrosion and wear-related advisories rather than active rectification. Between 2022 and 2025 the vehicle accumulated recurring brake pipe corrosion advisories at both front and centre locations, culminating in a Major failure on 19 February 2025 for excessively corroded nearside front brake pipes. The same 2025 test also flagged sub-frame corrosion front and rear, front anti-roll bar bush wear, and three worn rear lower suspension arm bushes, all of which appeared again as advisories at the re-test. The 2024 pass added broader front and rear suspension component corrosion advisories, and the 2026 test has now introduced a steering box wear note. This combination indicates an ageing chassis and underbody requiring ongoing, potentially costly structural and braking system attention. With 120,751 miles recorded over 28 years, annual mileage averages around 4,313 miles, which is exceptionally low for a vehicle of this age. Such figures typically reflect either very light use or extended periods of standing, and the MOT history supports the latter interpretation given the irregular testing intervals, particularly the long gap between 2014 and 2022 when the car appears to have been off the road for several years. Low annual mileage reduces wear on high-mileage components such as the engine internals, clutch and gearbox, but accelerates calendar-based deterioration of rubber, plastics, brake components and bodywork. Standing periods commonly produce binding brake calipers, corroded brake discs with surface pitting and uneven pad wear, oxidisation in the fuel system, perished hoses and seals, and chronic underbody corrosion, all of which align with the advisories seen across recent tests. The 2014 dangerous failure for a tyre with exposed plies and a leaking fuel tank also suggests the vehicle has a history of neglect that warrants careful verification of remedial work. For a prospective buyer, the recurring brake pipe corrosion advisories across nearly every test from 2022 to 2025 are a significant concern and should be physically inspected underneath the vehicle. Look for flaking, blistering or section loss along the full length of the brake lines, paying particular attention to unions, mounting clips and the pipes running along the sub-frames and centre tunnel, since corrosion in these concealed areas often progresses unseen between tests. The sub-frame corrosion advisory, repeated at the 2025 test, must be examined with the vehicle on a ramp to confirm structural integrity, checking for perforation, distortion or previous poor-quality repairs. The worn rear lower suspension bushes and front anti-roll bar bushes should be evaluated by hand for free movement and on a test drive for clonking over bumps, vague steering and poor turn-in response, while the steering box free play advisory warrants a careful check for sloppiness around the straight-ahead position and any knocking or fluid seepage from the box itself. On the road, listen for suspension knocks, feel for brake shudder or pulling under heavy braking, and observe any warning lamps on the dashboard. Beyond the recorded items, the low-mileage, standing-prone history demands a thorough age-related inspection regardless of MOT outcome. Check all tyres, including the spare, for sidewall cracking and perishing consistent with age rather than tread wear, and verify date codes as tyres over six years old should be replaced regardless of tread depth. Inspect brake discs for severe surface rust, lipping and any calipers that fail to release cleanly, which can cause uneven pad wear and pulling. Examine the underbody, wheel arches, jacking points and boot floor for rust, confirm the 12V battery holds charge under load as it is likely original or long-standing, and verify that all fluids including brake fluid, coolant, power steering fluid and engine oil have been changed on a calendar basis rather than purely mileage intervals. Service history stamps should be cross-referenced with the MOT gaps to confirm whether major items such as the fuel tank, suspension links and braking system were properly addressed after the 2014 failures. A pre-purchase inspection on a ramp by a BMW specialist is strongly recommended given the vehicle's age, corrosion trajectory and complex chassis components.
