2019 Audi Q5 2.0L Diesel · B6 RHR

Fuel economy for the 2.0 TDI Q5 in real-world conditions typically ranges from 35–45 mpg depending on driving style, with longer motorway runs returning the higher figure. Road tax sits in a higher band for diesel vehicles of this displacement, and as a premium SUV the insurance group will be higher than average — likely group 30–35, so obtain quotes before purchase. Annual servicing at a main dealer or Audi specialist typically costs £250–£400 depending on whether it is an interim or major service, with major services including brake fluid, air filter, and fuel filter replacements adding to the bill.

Estimated annual running costs including maintenance, fuel (assuming 10,000 miles at 40 mpg), tax, and insurance are likely to fall in the £2,400–£2,800 range, reflecting the premium nature of the vehicle. The DPF, AdBlue system, and quattro drivetrain servicing (transfer box and rear diff oil changes) are particular cost areas to budget for on a diesel Q5 of this age. Budget an additional £300–£500 annually for consumables such as tyres and brake wear to avoid surprises.

Begin with a thorough inspection of the rear braking system, as the 2025 MOT recorded both rear brake pads as wearing thin — at 45,080 miles they will likely need replacement soon and a full inspection of the discs is warranted. Check the rear reflectors and all lighting, addressing the minor failure items recorded in March 2023, though these are straightforward fixes. Inspect the underside for any signs of oil leaks, particularly from the timing chain cover and turbo oil feed pipes, which are known weak points on the 2.0 TDI engine.

Given the diesel powertrain, particular attention should be paid to the DPF, AdBlue injector and tank, and EGR valve, all of which can become costly on mid-life examples. Confirm the four-wheel-drive system functions correctly by testing on a slippery surface or by checking for any warning messages on the dashboard. A diagnostic scan at an Audi specialist will reveal any stored fault codes that have not yet triggered warning lights — particularly important for the DSG automatic gearbox (where fitted) and the emissions system, as these are common sources of expensive repairs on Q5s of this generation.
