2004 Volkswagen Passat 1.9L Diesel · CW04 BNV

A significant concern is the rear‑brake imbalance recorded on the 16 August 2026 MOT, which was classified as a major failure together with a non‑functional windscreen washer. This failure interrupts an otherwise clean recent history – the car has passed every other test since 2020, with only advisory notes on suspension corrosion, a slightly noisy off‑side front wheel bearing and a dash‑display brake‑pad warning. The latest result therefore signals a deterioration in the braking system that needs immediate attention before the vehicle can be considered road‑worthy. At 148 806 mi the Passat averages roughly 6 700 mi per year, a mileage rate that sits comfortably within normal usage for a 22‑year‑old model. The MOT record shows annual testing with no large gaps, indicating the odometer readings are likely reliable and the vehicle has not endured prolonged periods of inactivity. Nonetheless, the cumulative mileage means that wear items such as brake discs, pads, suspension bushings and wheel bearings will be approaching the end of their typical service lives and should be inspected for thinning, excessive play or corrosion. The rear‑brake imbalance suggests uneven wear or a possible hydraulic fault on the left side of the rear axle; listen for a pulsating pedal, uneven braking force or a high‑pitched squeal when the brakes are applied. Verify that the brake fluid is at the correct level and that there are no external leaks from the rear brake pipes. The inoperative windscreen washer points to a blocked nozzle or a failed pump – test the washer lever for any spray and check the reservoir for fluid. The advisory on slightly corroded suspension components warrants a visual inspection of the rear sub‑frame, control‑arm bushings and mounting points for rust flakes or pitting; any looseness when the wheel is rocked could indicate compromised structural integrity. The off‑side front wheel bearing noted as slightly noisy in 2021 should be re‑checked by feeling for grinding or humming at low speeds and by confirming that the wheel rotates smoothly without excessive play. Finally, the dash‑display brake‑pad warning from 2020 may reflect pads that are now near the minimum thickness; inspect both front and rear pads for wear indicators and ensure the discs are not scored. Before committing, have a qualified mechanic perform a comprehensive brake service, replace or repair the washer system, and carry out a full suspension and bearing examination. Addressing these items now will mitigate the risk of sudden brake failure, steering instability or premature component collapse, and will provide a clearer picture of any further hidden wear that the MOT advisories have hinted at.
