Should I check the MOT history before buying a 2013 Audi A6 S Line TDI?

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 2013 Audi A6 S Line TDI?

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 2013 Audi A6 S Line TDI?

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.

Is the 2013 Audi A6 S Line TDI reliable?

Based on MOT data from 632 vehicles, the 2013 Audi A6 S Line TDI has a first-time MOT pass rate of 92.7%, 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 2013 Audi A6 S Line TDI?

Yes. The MOT history will not show outstanding finance, insurance write-offs, or stolen status. An HPI check covers these areas and should be part of any used car purchase.

The 2013 Audi A6 S Line TDI is a notably unreliable proposition at MOT time, with a first-time pass rate of just 63.6% against the UK average of 80%—meaning roughly one in three fail their test. The diesel variant, which dominates this cohort at 624 of 632 vehicles, performs no better at 63.3%, so fuel type offers no hiding place here.

At just over 101,000 miles median mileage, these cars are running reasonably hard for their age, yet they're averaging only 0.3 failures per vehicle, suggesting the failures are concentrated among a subset of problem cars rather than universal wear items. Before committing to one, budget for pre-purchase inspection by a diesel specialist and ask the seller for full service history—this generation's TDI engines are sensitive to neglect, and gaps in maintenance often explain the weak pass rates you're seeing.

The 2013 Audi A6 S Line TDI passes its MOT first time more often than most UK vehicles (92.7% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.
