Should I check the MOT history before buying a 2009 Audi A4 SE TDI 6sp?

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 2009 Audi A4 SE TDI 6sp?

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 2009 Audi A4 SE TDI 6sp?

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 2009 Audi A4 SE TDI 6sp reliable?

Based on MOT data from 928 vehicles, the 2009 Audi A4 SE TDI 6sp has a first-time MOT pass rate of 81%, 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 2009 Audi A4 SE TDI 6sp?

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.

This 2009 Audi A4 TDI is a serious reliability concern—just 39.9% pass first time against the UK average of 80%, meaning four in five examples fail their MOT on the first attempt. The good news is that dangerous defects are essentially absent from this cohort, so failures are typically fixable rather than safety-critical issues.

At 144,877 miles on average, these cars are well-worn, which partly explains the high failure rate, but the 0.68 average failures per vehicle suggests systemic mechanical wear rather than isolated problems. If you're considering one, budget for repairs before purchase and have a pre-buy inspection focus on suspension, braking components, and diesel engine condition.

The 2009 Audi A4 SE TDI 6sp passes its MOT first time at roughly the UK average rate (81%) — solid but worth checking this vehicle's history carefully.
