Audi A8 Black Ed 50 TDI MHEV Quat A (2023)
2023 Audi A8 Black Ed 50 TDI MHEV Quat A
CarHunch analysed 122 real MOT records for the 2023 Audi A8 Black Ed 50 TDI MHEV Quat A. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This A8 is failing its MOT at an alarming rate: just 10.4% pass first time compared to the UK average of 80%, and the diesel variant performs even worse at 9.6%. With zero dangerous defects recorded across 122 vehicles, the failures aren't safety-critical, but such a poor pass rate suggests systemic issues—possibly emissions-related or design quirks specific to this model generation.
At 23,761 miles median, these cars are still very young and low-mileage, yet they're racking up failures at a rate the data doesn't fully explain. Check the specific MOT failure notes before buying; this cohort's 45 median CarHunch score reflects genuine structural reliability concerns, and you should budget for early remedial work rather than assuming "new" means trouble-free.
What to check before buying a 2023 Audi A8 Black Ed 50 TDI MHEV Quat A
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.
