Advice for buyers
What should I look for in a used Audi Q5 4x4?
The Q5’s 2.0-litre diesel engine requires a new cambelt every five years or 140,000 miles, for which Audi charges a lot, so be sure factor this into the purchase price if necessary.
There’s a small chance there might be a bit of rust, particularly around the wheel arches, and check the the clutch on manual versions operates smoothly as a replacement will cost the best part of £1000. The manual gearbox should also have a direct, positive shift, while the dual-clutch S tronic automatic should respond keenly when you put your foot down and be smooth when slowing to a stop. Also make sure that reverse gear engages and that the S tronic gearbox has been serviced to schedule (it requires new oil and a filter every 38,000 miles).
Worn ball joints have been an issue with some Q5s, so listen out for creaks from the suspension. Electrical glitches are also common, particularly linked to the air conditioning, boot switch and the tyre pressure monitoring system.
Diesel Q5s are fitted with a diesel particulate filter (DPF) which needs to be cleared every so often by taking the car on a longer journey. Failure to do so can also result in an expensive repair bill.
