Should I check the MOT history before buying a 2021 Audi A4 Sport Ed 35 TFSI MHEV S A?

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 2021 Audi A4 Sport Ed 35 TFSI MHEV S A?

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 2021 Audi A4 Sport Ed 35 TFSI MHEV S A?

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.

Based on MOT data from 201 vehicles, the 2021 Audi A4 Sport Ed 35 TFSI MHEV S A has a first-time MOT pass rate of 92.5%, indicating generally reliable for its class. Always check the full MOT history of any specific vehicle before buying.

Do I need an HPI check when buying a 2021 Audi A4 Sport Ed 35 TFSI MHEV S A?

This 2021 Audi A4 is notably reliable, with a 92% first-time MOT pass rate that sits well above the UK average of 80%—a strong sign of engineering quality. The dangerous defect rate of 12.4% is moderate and not a major concern, though worth noting when budgeting for repairs.

At an average mileage of 34,963 km, these cars are still relatively fresh, and the low failure rate of just 0.23 per vehicle backs up their dependability. When you do take one to MOT, expect around 1.5 advisories (mostly minor wear items) rather than serious problems—but before buying, run a pre-purchase inspection to catch any electrical or suspension niggles early, as hybrid systems and Audi's infotainment can be expensive to fix out of warranty.

We have limited data for the 2021 Audi A4 Sport Ed 35 TFSI MHEV S A — treat the figures below as indicative rather than definitive.

⚠️ Around 1 in 8 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.
