Should I check the MOT history before buying a 2004 Volkswagen Passat?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

What corrosion should I look for when inspecting a 2004 Volkswagen Passat?

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

How are tyres and brakes typically on a 2004 Volkswagen Passat?

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.

The 2004 Passat passes its MOT first time in only 74.1% of cases, notably below the UK average of 80%, and nearly a quarter of these cars (24.9%) have recorded dangerous defects at some point—a serious red flag for buyers prioritising safety. The diesel-dominated fleet shows a marginally weaker pass rate (73.8%) than petrol variants (76.5%), suggesting diesel engines in this generation carry slightly higher maintenance risk.

These Passats typically carry 110,000 miles, and when they do fail MOT they average 4.2 failures per test alongside 19 advisories, pointing to cumulative wear in suspension, braking, and emissions systems rather than isolated faults. Before buying one, get a full pre-purchase inspection focusing on brake condition, suspension geometry, and exhaust system integrity—don't rely on a recent pass to mean the car is sound.

The 2004 Volkswagen Passat has a below-average first-time pass rate (74.2% vs ~80% UK average) — check the specific vehicle's full MOT history carefully before buying.

⚠️ Over 1 in 5 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.

For context

⚠️ Below average. More vehicles in this cohort fail their first MOT than typical. Scrutinise this vehicle's history — look for recurring issues, not just the latest result.

🔧 Expect consumable spend. An average of 19 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.

🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 28,439 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
