2015 Audi Q5 3.0L Diesel · CU08 RTS

The 3.0 TDI diesel engine typically returns around 40–47 mpg combined, though real-world figures from a vehicle at 132,082 miles may be nearer the lower end. Road tax falls in a higher band due to the large engine capacity, so expect annual VED costs in the £200–£300 range depending on the exact list price recorded. Insurance for an Audi Q5 3.0 TDI typically sits in group 35–40, meaning premiums of £600–£900 per year for an experienced driver.

Servicing at main dealers or specialists will be pricier than for smaller vehicles — expect annual maintenance including oil change, filters, and inspections to cost £250–£450. Timing chain replacement, if ever required, can cost £1,000–£1,800, so confirming the chain has been inspected or replaced is worthwhile. Including fuel, tax, insurance, and maintenance, estimated annual running costs come in at approximately £1,400–£1,800.

Pay close attention to the front suspension components flagged in the January 2026 MOT: both nearside and offside upper and lower suspension arm pins/bushes were noted as worn. The fact that the April 2026 test recorded no issues suggests either the components were replaced in the interim or the wear was borderline — verify this directly with the seller and inspect the bushes visually if possible. General suspension condition, including springs (a common Audi Q5 failure point per the model aggregate data, which lists coil springs as a top failure reason) and shock absorbers, should be checked for any knocking or sagging.

The April 2023 MOT advisories noted brake disc wear on all four corners. Inspect current brake disc condition, pad thickness, and look for scoring or lipping. For the 3.0 TDI engine specifically, listen for diesel knock on cold start, check for black smoke on acceleration, and inspect turbocharger hoses for splits. Examine the underside for any oil seepage from the sump, cam chain area, and rear main seal. Inspect the alloy wheels for kerbing damage, check all four tyres for even wear (a tyre nail was noted in January 2026), and verify the tyre age markings are within a reasonable range.
