Volkswagen Passat Sel TDI S A (2020)
2020 Volkswagen Passat Sel TDI S A
CarHunch analysed 1,339 real MOT records for the 2020 Volkswagen Passat Sel TDI S A. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 2020 Passat TDI diesel is a solid performer on the MOT bench, passing first time at 86.7%—a clear 6.7 percentage point lead over the UK average—and only 13.8% have ever recorded a dangerous defect, which is well below the worry threshold. Diesel reliability here is straightforward; there's no petrol variant to compare against, so what you're looking at is genuine consistency in this engine type.
At a median 51,556 miles for a four-year-old car, these Passats are running right on schedule mileage-wise, and the 0.34 average failures per test suggests owners aren't facing major surprise repairs. The 3.0 advisories per vehicle points to routine wear items (brakes, suspension, wiper blades) rather than systemic weakness—typical for a car of this age and mileage. If you're considering one, get a pre-purchase inspection focused on turbocharger condition and DPF cleanliness, as diesel-specific issues tend to cluster around those components.
What to check before buying a 2020 Volkswagen Passat Sel TDI S A
Practical pre-purchase checks for this age and model.
- 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
- 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
- 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
