2009 Volkswagen Passat 2.0L Diesel · LS 6288

The most recent MOT, carried out on 27 November 2025, was passed but returned three advisories – rear sub‑frame corrosion (not yet seriously weakened), and severely deteriorated dust‑covers on both front upper anti‑roll bar ball joints. Prior to that the car passed in December 2024 with a rear‑axle corrosion advisory and in November 2023 with a near‑side rear tyre nail advisory. The only failure in the record occurred in December 2022, when multiple tyres were deemed dangerous and the exhaust emissions exceeded the legal limit. Since that failure the MOT results have shown a clear improvement, moving from outright failure to a series of clean passes with only non‑fatal advisories, indicating that the owner has addressed the most critical safety items but that corrosion and component wear remain ongoing concerns. With 68,938 mi recorded on a vehicle first registered in 2009 the average annual mileage works out at roughly 4,000 mi per year, well below the UK average for a car of this age. Such low utilisation often points to long periods of inactivity or only occasional use, which can be a double‑edged sword: the power‑train and drivetrain components are likely to have experienced relatively little wear, yet prolonged standing can accelerate rust formation on chassis members, promote battery sulphation, and cause rubber components such as seals, hoses and tyre sidewalls to perish. There are no obvious mileage spikes that would suggest a period of intense use, so the wear pattern should be fairly uniform, but the age of the vehicle means time‑related degradation must be scrutinised. A prospective buyer should give particular attention to the rear sub‑frame and rear axle for signs of advancing corrosion – look for flaking paint, rust pits, or any distortion when the rear suspension is rocked. Any clunk, knock or excessive play when applying the brakes or compressing the rear springs could indicate that the sub‑frame is losing structural integrity or that the anti‑roll bar ball‑joint dust‑covers, now severely deteriorated, are allowing ingress of moisture to the joints. On a test drive listen for rattles from the rear suspension, feel for any wandering or uneven response when cornering, and check that the steering feels solid with no excessive play. Verify that all four tyres have a tread depth well above the 1.0 mm minimum, are free from sidewall cracks, bulges or embedded objects, and that the tyre ages are consistent (ideally no tyre older than six years regardless of tread depth). Because the car previously failed emissions, a quick visual inspection of the exhaust system for cracked manifolds, damaged catalytic converter housing, or black soot deposits is advisable, and a diagnostic scan can confirm that the O₂ sensors and catalytic converter are functioning within specification. Given the vehicle’s age and low mileage, time‑based maintenance items should be addressed even if they appear service‑free. Inspect the 12 V battery for sulphation, low cranking voltage and swollen case; a load test or replacement may be prudent if the car has been stored for extended periods. Examine brake discs and pads for surface rust, glazing or uneven wear that can develop when a car sits idle; ensure the calipers move freely and that there is no brake‑fluid leakage at the wheel cylinders. Check the condition of engine oil, coolant, brake fluid and gearbox oil – fluids can absorb moisture and lose effectiveness after several years, so a full fluid change in line with the manufacturer’s calendar service schedule is recommended. Finally, request a complete service book and any receipts for recent component replacements to corroborate that the advisories noted in the MOTs have been remedied and that the car has been maintained in line with Volkswagen’s service intervals.
