Is the Audi A6 ULEZ Compliant?
Based on 129,378 MOT tests, around 38% of Audi A6s still on the road are likely to meet London's ULEZ standards, and about 45% are likely to be charged. For the remaining 18%, it depends on the exact Euro standard or month of registration.
The fuel mix matters: tested cars were 91% diesel, 9% petrol. Diesel A6s are generally compliant from 2016, while diesel cars from 2013 or earlier are likely to be charged. Petrol A6s are generally compliant from 2006, while petrol cars from 2000 or earlier are likely to be charged.

How ULEZ rules apply to the A6
Cars that miss the standard pay £12.50 for each day they're driven in the zone. Petrol and petrol-hybrid cars need Euro 4 (most from 2006), while diesels need Euro 6 (most from September 2015).
- Diesel (91% of A6s tested): likely compliant from 2016; 2013 and earlier are likely to be charged.
- Petrol (9% of A6s tested): likely compliant from 2006; 2000 and earlier are likely to be charged.
A6s from 2014 and 2015 sit on the boundary (18% of those tested): some were built to the required standard before it became compulsory. The Euro standard is sometimes on the V5C logbook, or Audi can confirm it. Our ULEZ calculator can help.

Buying a used Audi A6 for London: what the MOT data shows
The Audi A6s in this data were first registered between 1995 and 2021. 2016 was the most common year, with 13,524 tests (10% of the total), and half were registered in 2014 or later.
A6s from likely-compliant years passed their MOT first time 87% of the time, at an average of 64,518 miles. Older ones likely to be charged passed 72% of the time with 136,474 miles on average, so a compliant car is usually the more reliable buy as well as the cheaper one to drive in London.
On a budget, the oldest diesel A6s likely to comply are from 2016. 12,736 of them were tested; 2016 cars passed first time 86% of the time and averaged 77,340 miles. Check the Euro standard on the V5C before you buy one from around then.
On a budget, the oldest petrol A6s likely to comply are from 2006. 472 of them were tested; 2006 cars passed first time 65% of the time and averaged 162,636 miles. Check the Euro standard on the V5C before you buy one from around then.
Whichever year you choose, check the A6's weak spots. The most common MOT failures were tyres: "tread depth below requirements of 1.6mm" (2.9% of tests); lights and electrics: "not working" (2.3%); suspension: "pin or bush excessively worn" (2.2%). The most frequent advisory was "tread depth below requirements of 1.6mm", on 17.8% of tests.
Overall, 79% of A6s passed first time, noticeably above the 71% average for all cars, and they had covered 102,678 miles on average, more than the 73,145-mile average.
