Should I check the MOT history before buying a 2021 Volkswagen Passat R Line TDI S A?

This 2021 Passat R-Line TDI is significantly more reliable than average, with a 91.1% first-time pass rate well above the UK's 80% baseline—diesel owners needn't worry about fuel-type weakness here. The dangerous defect rate of 6.4% is modest enough not to be a red flag for most buyers.

At just under 50,000 miles median, these cars are lightly used for their age, which explains why they average only 0.18 failures per vehicle. The 1.7 advisories per test suggest minor maintenance items crop up occasionally, so budget for routine brake pads and exhaust work—but check the service history carefully before buying to confirm preventative work hasn't been skipped.

The 2021 Volkswagen Passat R Line TDI S A passes its MOT first time more often than most UK vehicles (94.2% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.

⚠️ Around 1 in 20 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

✅ Good baseline reliability. A 94.2% first-time pass rate puts this well above the UK average — it's a well-sorted vehicle in this age bracket.

🔧 Expect consumable spend. An average of 1.7 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 683 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.
