Used Audi A6: what to check before you buy

Updated 4 September 2026 · read from the live market and the A6 service schedule

Before you buy a used Audi A6 in Bengaluru, here is what actually matters — built from the 63 on sale right now and the manufacturer’s own service schedule, not generic advice. Every number below is this model, this city, this morning.

What that mileage & age mean

• It's chain-driven, so there's no scheduled belt replacement — but a rattle for a second or two on a cold start points to a stretched chain or tensioner, which is a real bill. Listen on the test drive.
• At this mileage it should already be due transmission fluid, spark plugs — ask for the bills, not just a verbal yes.
• At around 9 years old, the rubber and electrics matter as much as the engine — perished hoses and bushes, a tired AC compressor, and rust in the sills, wheel arches and boot floor.

Where to look hardest on a Audi A6

• On a diesel, have the turbo, injectors and (where fitted) the DPF checked, and confirm the timing belt's service history — these are the expensive failures.
• On an automatic, feel for jerks or slip on a test drive and ask when the transmission fluid was last changed — a rebuild is dear.
• Whatever the paperwork says, the reading on the clock is worth verifying — roughly one in three used cars carries a wound-back odometer.

Is the odometer genuine?

The typical Audi A6 on sale here reads about 68,000 km. A reading well below that for the year is worth a second look — roughly one in three used cars has been wound back. InspektAI verifies the real kilometres against ECU, service and insurance records as a paid add-on, so you buy on the true number.
