Common questions
Does the Audi A7 (4K) have a timing chain or a timing belt?
1.8 / 2.0 TSI / TFSI (EA888): chain; 2.7 / 3.0 TDI V6: chain; 1.4 / 1.6 / 2.0 TDI (EA288): belt · 210,000 km / every 120 mo.
What are the known problems with the Audi A7 (4K)?
The faults with the highest risk: timing chain wear (150,000–250,000 km, €3,000–5,000); timing chain tensioner (pre-2013) (80,000–160,000 km, €1,000–2,000); DCT mechatronic / solenoids (120,000–220,000 km, €800–2,000); EGR / DPF (120,000–200,000 km, €400–1,800). The full list by engine is on this page.
What does the Audi A7 (4K) most often fail its roadworthiness test on?
In UK roadworthiness tests in 2024, at 50–100 thousand km this model most often failed on: tyres and wheels (6.6 %), lights, wipers and visibility (2.1 %), exhaust, emissions and leaks (2.1 %). It fails more often than an average car of the same age and mileage on: exhaust, emissions and leaks. It fails less often than average on: brakes, suspension, lights, wipers and visibility.
What should you check when buying a used Audi A7 (4K)?
Before you buy, ask an authorised dealer to check by VIN whether the car has any open recalls. If the engine has a timing belt, ask for the invoice for its replacement: with no proof, assume it has not been done. On the test drive, watch for these signs: rattle at rear of engine; rattle on start. The full checklist is in the guide to buying a used car.
