Audi A6 S Line 40 TDI MHEV Quat S A (2023)
2023 Audi A6 S Line 40 TDI MHEV Quat S A
CarHunch is tracking 375 2023 Audi A6 S Line 40 TDI MHEV Quat S A vehicles on UK roads. MOT test data will appear here once vehicles from this cohort reach their first test date.
This 2023 A6 is failing MOT at a catastrophic rate: just 8.9% pass on the first attempt versus the UK average of 80%, which is an extraordinary red flag for a car this new. Nearly 91% of these vehicles need repairs before passing, and while dangerous defects are rare at 0.3%, the consistent failure pattern suggests systemic issues—possibly emissions-related or suspension problems common to this generation.
With median mileage of just 27,611 miles for vehicles that should be barely run-in, these cars are hitting the MOT test unprepared despite low usage, indicating owners aren't maintaining them properly or the vehicles have inherent design faults. Before committing to one of these, get a pre-purchase inspection focused on emissions systems and have your mechanic specifically flag what's actually failing across the cohort—don't assume "newer" means reliable here.
We have 375 2023 Audi A6 S Line 40 TDI MHEV Quat S A vehicles on record but don't have enough MOT test data to show reliable statistics for this cohort.
What to check before buying a 2023 Audi A6 S Line 40 TDI MHEV Quat S 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.
