How ULEZ rules apply to the A4
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 (68% of A4s tested): likely compliant from 2016; 2013 and earlier are likely to be charged.
- Petrol (32% of A4s tested): likely compliant from 2006; 2000 and earlier are likely to be charged.
A4s from 2014 and 2015 sit on the boundary (15% 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 A4 for London: what the MOT data shows
The Audi A4s in this data were first registered between 1995 and 2021. 2016 was the most common year, with 22,396 tests (8% of the total), and half were registered in 2012 or later.
A4s from likely-compliant years passed their MOT first time 79% of the time, at an average of 74,371 miles. Older ones likely to be charged passed 67% of the time with 128,519 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 A4s likely to comply are from 2016. 15,467 of them were tested; 2016 cars passed first time 80% of the time and averaged 73,459 miles. Check the Euro standard on the V5C before you buy one from around then.
On a budget, the oldest petrol A4s likely to comply are from 2006. 6,261 of them were tested; 2006 cars passed first time 62% of the time and averaged 135,538 miles. Check the Euro standard on the V5C before you buy one from around then.
Whichever year you choose, check the A4's weak spots. The most common MOT failures were suspension: "fractured or broken" (3.6% of tests); tyres: "tread depth below requirements of 1.6mm" (3.4%); lights and electrics: "not working" (2.9%). The most frequent advisory was "tread depth below requirements of 1.6mm", on 18.4% of tests.
Overall, 73% of A4s passed first time, roughly in line with the 71% average for all cars, and they had covered 102,275 miles on average, more than the 73,145-mile average.
