2020 Audi A5 S LN ED 1 45 Tfsi Mhev Q SA 2.0L Petrol · 31 M

The 2.0 TFSI petrol engine in 45 TFSI form is officially rated in the low-to-mid 40s mpg combined, though real-world driving in a Sportback of this weight typically returns 35-40 mpg. As a Euro 6 AP petrol registered from October 2020, it attracts the standard £195 annual VED rate from year six onwards. Insurance is likely to fall into group 30-35 territory given the performance and quattro set-up, so quotes should be obtained before purchase.

Servicing tends to follow variable intervals on Audi's long-life regime, but budget for around £300-£500 per major service at a specialist, rising higher at a main dealer. quattro-related components such as haldex filters, brake discs, and DSG oil changes can add to the bill, and replacement tyres on larger Sport alloys are a recurring cost. Estimated annual running costs including fuel, tax, insurance, and routine maintenance typically fall in the £2,400-£2,900 range.

The MOT history shows tyre damage advisories at the 2024 test on the nearside rear and offside front corners, so a thorough inspection of all four tyres should be a priority, including tread depth, sidewall condition, and whether mismatched brands or sizes have been fitted. The latest 2025 pass was completely clean, but this does not rule out developing issues, so check for uneven wear which can indicate alignment, suspension, or tracking problems. As the model aggregate flags tyres as the top failure reason, treat tyre condition as a key negotiation point.

For the 2.0 TFSI MHEV specifically, listen for any rattling or hesitation on cold start, which can point to timing chain stretch, a known area of attention on earlier EA888 generations. Inspect the underside for any oil seepage from the sump, cam chain tensioner area, and the turbocharger oil feed lines. On the quattro system, check that the haldex coupling has been serviced and that there is no binding or vibration under hard cornering. Finally, confirm that all dashboard warning lights clear on start-up and that the 48V mild-hybrid system shows no faults in the MMI or via a diagnostic scan.
