2004 Volkswagen Passat 1.9L Diesel · KW04 HVJ

The vehicle is currently roadworthy, but the maintenance history reveals a trend of reactive rather than proactive care. While it passed its most recent test in January 2026 at 86,730 miles, this followed a significant failure just two weeks prior involving multiple critical safety and mechanical faults. The January 16th failure flagged a supplementary restraint system fault, an inoperative engine management light, and split drive shaft boots. The presence of these high-priority failures suggests that the owner only addresses mechanical issues when forced by the MOT tester, rather than identifying faults during routine servicing. The mileage profile is exceptionally low for a 22-year-old vehicle, averaging approximately 3,900 miles per year. The data shows a notable gap in usage between April 2024 and January 2026, where the car covered only 1,474 miles in nearly twenty-one months. While low annual mileage generally reduces wear on the drivetrain and braking components, the long periods of standing often accelerate the degradation of rubber components and seals, which is evidenced by the persistent deterioration of the drive shaft CV boots noted across several testing years. A buyer must closely inspect the structural integrity of the vehicle, specifically the front and rear sub-frames. Both have been flagged for corrosion since at least 2022, and while currently described as not seriously weakened, the recurring advisories indicate an ongoing process of oxidation that will eventually lead to structural failure. The buyer should also verify that the engine management system and SRS faults have been properly rectified, as these were major failures in early 2026. Given the history of split CV boots, a physical inspection of the front drive shafts for grease leakage or play is essential to ensure the joints have not suffered internal damage from grit.
