2004 BMW 3 Series 2.0L Diesel · WN04 DZB

The 2004 BMW 3 Series presents a mixed maintenance trend, showing a recent improvement in structural advisories but a persistent neglect of basic consumables. The most recent MOT test on 2025-10-09 at 202,158 miles resulted in a pass, though the tester flagged corrosion on the rear subframe mounting prescribed area and an offside rear tyre worn to the legal limit. This follows a fractured offside rear coil spring failure on 2022-10-07 at 193,424 miles, a serious mechanical defect that was promptly rectified given the subsequent pass in October 2022. The recurring tyre wear advisories point to a pattern of deferred routine maintenance. Accumulating 202,158 miles over 22 years yields an average annual mileage of roughly 9,190 miles, which is entirely typical for a vehicle of this age. The records show consistent usage, with the mileage increasing by approximately 2,700 to 2,800 miles annually between October 2022 and October 2025. No significant gaps or sudden spikes in the odometer readings appear in the data, indicating the car has been driven regularly rather than sitting idle for extended periods. A physical inspection must prioritize the structural integrity of the rear end, given the history of corrosion and suspension failure. The tester noted corrosion on the offside rear suspension mounting prescribed area in October 2023 and the nearside rear subframe mounting area in October 2025. While both were deemed not excessive at the time of testing, a buyer must closely examine these specific prescribed areas for advanced rust or fracturing, particularly around the rear sills where the previous coil spring failed. The repeated advisories for edge-worn rear tyres suggest potential misalignment or worn suspension bushes that remain unaddressed. Inspect the condition of the offside front wheel arch for spreading corrosion, and verify the operation of the nearside registration plate lamp.
