2007 BMW Z4 3.0L Petrol · WA56 URR

A persistent oil leak and the long‑standing corrosion of the brake pipe are the dominant themes in this Z4’s MOT history; the June 2026 test still recorded the brake pipe as corroded and covered in grease, while an oil‑leak advisory has appeared on every test from 2020 through 2025, indicating a leak that has not progressed to an excessive level but has not been rectified. Tyre condition also stands out, with a 2023 failure for exposed ply on both front tyres and a near‑side rear tyre worn to the legal limit, followed by multiple advisory notes for nail punctures and a rear coil‑spring corrosion warning in 2020. Apart from these issues, the car has otherwise passed its annual tests, suggesting that the identified defects have remained confined to the same components without new failures emerging. At 134 077 mi the vehicle averages roughly 7 000 mi per year, a mileage rate that sits comfortably within normal usage for a 19‑year‑old sports coupe. The MOT record shows no large gaps in testing, with yearly examinations from 2020 onward, so the mileage progression appears steady rather than indicative of periods of intense short‑term use or prolonged storage. Mechanically, this moderate annual accumulation means wear on consumables such as brake pads, suspension bushings, and tyre tread will be in line with age‑related degradation rather than accelerated mileage‑driven failure, but the recurring oil‑leak advisory suggests a component that may be approaching a threshold where the leak could become excessive. Prospective buyers should focus on the oil‑leak source: inspect the engine bay and under‑tray for fresh oil stains, check the condition of the oil pan gasket, valve cover seals, and any visible hoses, and listen for any dripping or splashing while the engine is running. The corroded brake pipe warrants a hands‑on examination of the front brake lines for rust perforation, especially where the pipe is coated in grease; any soft spots, pin‑hole leaks, or a spongy pedal feel should be taken as a sign that replacement is required. Tyre health must be verified beyond the MOT advisory – examine tread depth across the width, inspect sidewalls for cuts, cracks or exposed cords, and feel for any vibration or pulling that could indicate uneven wear or internal damage. The rear coil‑spring corrosion noted in 2020 should be probed for rust penetration that could compromise spring integrity, and the rear brake assembly noise reported should be checked for loose or worn components that might cause judder or reduced braking efficiency. A thorough pre‑purchase inspection by a qualified technician is advisable to address the oil‑leak origin, replace the front brake pipe, and fit a fresh set of tyres that meet safety standards. Replacement of the rear coil spring, remediation of the rear brake assembly noise, and renewal of the fuel‑cap seal and wiper blades are relatively low‑cost items that will remove the outstanding advisories. Confirm that any remedial work is documented and that a subsequent MOT is passed before finalising the purchase, ensuring the vehicle’s roadworthiness aligns with the documented history.
