What a 2025 Q7 is advertised for

Asking price

$95k to $127k

Odometer

2k to 10k km

Asking prices, not sale prices: the middle 60% of the 404 advertised in the last 12 months, one listing per car.
- Get the rego or VIN From the ad or the seller. Enter it at the top of this page: the make, model and year should match the ad.
- Compare the price With what similar cars are advertised for.
- Ask the seller How long they have owned it, why they are selling, any accidents and any money owing.
- Ask for the service book And for the engine to be cold when you arrive.
- Meet in daylight In dry weather. For a private sale, at the seller's home: the address should match the registration papers.
Inspection

- Panels and paint Uneven gaps, paint that does not quite match and overspray on rubber seals point to accident repairs.
- Rust Under the doors, around the wheel arches and under the boot floor.
- Tyres At least 1.5 mm of tread, even wear across each tyre, and a spare.
- Glass and lights No chips or cracks in the windscreen, and every light works.
- Oil and coolant Check them cold. Milky oil under the filler cap, or oil in the coolant, can mean a head gasket fault.
- Cold start Watch the exhaust and listen for rattles in the first few seconds.
- Wear inside The pedals, steering wheel and driver's seat should fit the odometer reading.
- Warning lights and controls Lights come on with the ignition and go out once the engine runs. Try the air conditioning, windows, locks and screen.
- Flood signs A damp smell, water marks or silt under the carpets.
What to check on a Q7
- Diesel health Take a long drive including highway speeds and check for limp mode, DPF or engine warnings. Ask how the car was used and whether the DPF has been replaced.
- Coolant Check the level when cold, look for leaks under the car and ask whether coolant has been topped up between services.
- Air suspension On cars fitted with it, check the car sits level after standing, rises and lowers in every mode without warnings, and the compressor does not run constantly.
- Electronics Run the MMI, navigation, cameras, keyless entry, USB ports, power tailgate and driver aids through their paces.
- Brakes and tyres Feel for pulsing under braking, look for lips on the discs and check tread depth. Price these into your offer.
- Water leaks Check the headlining around the sunroof, the boot floor and the area behind the tail lights for stains or damp.
- Recall paperwork Ask for proof of recall work, especially the steering shaft bolt, rear axle nuts and fuel delivery unit on 4M models.
- Service history Look for regular servicing at the scheduled intervals by Audi or a specialist. Gaps on a Q7 usually mean deferred, costly work.
The Q7's known problems, in full
Test drive
0 of 5
- 20 minutes or more On slow streets and at highway speed.
- Steering and brakes It runs straight with your hands light on the wheel, and stops straight without shudder or squeal.
- Gear changes Smooth, with no slipping or flaring revs. In a manual, a clutch that bites near the top of the pedal may be worn.
- Noises Knocks over bumps, and whines or hums that rise with speed.
- Temperature and leaks The gauge settles and stays put. After the drive, look under the car for fresh drips.
Paperwork
0 of 7
- Money owing A car with finance owing on it can be repossessed after you have paid for it. A PPSR check shows it.
- Write-off A statutory write-off can never be registered again, and a repairable write-off needs an inspection first.
- Odometer Compare the reading with earlier records of the car: service book stamps, earlier listings and other records.
- VIN match The VIN on the car matches the registration papers and the PPSR certificate.
- Seller's licence The name and address match the registration papers.
- Safety certificate In Queensland the seller needs a current safety certificate, and in Victoria a roadworthy certificate is needed to transfer the registration.
- Receipt The date, the price, the VIN and rego, and both names and signatures.
Money owing and write-offs on the Q7

6% had money owing

10% were recorded as written off

Of about 150 used Audi Q7 checked on Carify since November 2023. Every car checked: 9% had money owing and 13% were written off.

These are cars people chose to check before buying, so they are not a share of every Q7 on the road. Money owing is what was registered against the car on the day it was checked.
Where to find the VIN on a Audi

Q5 (FY) · where to find the VIN
1. 1. Base of the windscreen. Passenger side. Read it from outside.
2. 2. Engine compartment. Right-hand side, stamped in. Open the bonnet.
3. 3. Under the boot floor. On the vehicle data sticker. Lift the floor panel.
Drawn on one Audi model: others may differ, and the owner's manual lists the places. Reading a Audi VIN

Older cars also carry a compliance plate, usually under the bonnet or on a door pillar. A car supplied new since mid 2021 may have none: it is entered on the Register of Approved Vehicles instead.
