Should I check the MOT history before buying a 2020 Audi S5 Edition 1 TDI MHEV Quat 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 2020 Audi S5 Edition 1 TDI MHEV Quat 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 2020 Audi S5 Edition 1 TDI MHEV Quat 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 129 vehicles, the 2020 Audi S5 Edition 1 TDI MHEV Quat A has a first-time MOT pass rate of 89.6%, 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 2020 Audi S5 Edition 1 TDI MHEV Quat A?

This 2020 Audi S5 diesel edges past the UK average with an 83.3% first-time pass rate, suggesting solid baseline reliability—though 17.1% of these vehicles have experienced a dangerous defect at some point, which is worth factoring into your inspection checklist. The relatively low 0.43 average failures per vehicle is encouraging, but the 2.4 advisories suggest minor wear items are cropping up regularly.

At 36,000 miles median, these cars are running slightly below the typical mileage for their age, which should mean less accumulated stress on mechanical systems. Before purchase, budget for those recurring small fixes and get a pre-buy inspection that specifically checks suspension, brakes, and emissions equipment—the areas where this model tends to generate advisories.
