2004 BMW Z4 3.0L Petrol · EK54 ORP

The 2004 BMW Z4 currently presents a stable mechanical condition, evidenced by its clean pass on 29 July 2025 at 139,008 miles with zero defects recorded. This outcome indicates a resolving trend regarding immediate safety faults, as the vehicle required rectification of a supplementary restraint system warning lamp and a rough offside front wheel bearing just six days prior. The tester flagged no corrosion or suspension issues in the most recent examination, suggesting previous repairs or replacements addressed the recurring advisories from earlier years. Accumulating 139,008 miles over 22 years equates to roughly 6,319 miles annually, a typical figure for a vehicle of this age. The MOT records demonstrate consistent, regular use rather than prolonged periods of inactivity. Between the July 2023 test at 125,818 miles and the August 2024 test at 131,310 miles, the Z4 covered 5,492 miles. This increased slightly to 7,689 miles over the following twelve months leading to the July 2025 test at 138,999 miles. Such steady consumption implies routine wear on drivetrain and suspension components, though no severe mileage spikes suggest recent high-stress usage. Despite the recent clean pass, a physical inspection must scrutinise the front suspension and structural integrity given the historical pattern. Between 2023 and 2024, the tester repeatedly flagged corrosion on the nearside and offside upper Macpherson strut mountings, alongside excessively worn lower suspension arm ball joints that required replacement. Buyers should closely examine the inner wing arches and strut tops for advanced corrosion, which can compromise structural integrity on older BMWs. The recurring offside rear tyre wear and inner tyre cracking suggest potential tracking misalignment or perishing rubber, demanding a thorough check of the rear suspension geometry and tyre condition. Finally, the minor oil leak noted in August 2024 warrants investigation, as seepage from the Z4's ageing gaskets can escalate if left unattended.
