Audi A4 SE TDI (2011)
2011 Audi A4 SE TDI
CarHunch analysed 451 real MOT records for the 2011 Audi A4 SE TDI. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 2011 Audi A4 SE TDI is notably less reliable than the UK average, with a first-time pass rate of just 65.6% against the 80% benchmark—meaning over a third of these cars fail their MOT on the first attempt. The good news is that dangerous defects are absent from this cohort, so safety isn't the issue; instead, you're looking at a higher frequency of correctable mechanical problems.
At 134,000 miles average, these cars are well-used, and that mileage correlates with the 0.72 failures per vehicle on record—typical wear items like suspension, brakes, and emissions components are the culprits. Before buying one, get a pre-purchase inspection focusing on the timing chain (a known weak point on this generation), exhaust emissions system, and suspension condition, because the MOT failure pattern suggests these are the areas most likely to need attention.
What to check before buying a 2011 Audi A4 SE TDI
Practical pre-purchase checks for this age and model.
- 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
- 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
- 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
