Buying Tips for 2015–2016 Audi A5 Mk1 (8T/8F)

  • ✓Pre-2012 2.0 TFSI cars need proof of piston-ring work or genuinely modest oil use - anything vague is a red flag
  • ✓FWD automatics need excellent Multitronic servicing, while quattro S tronic cars should feel clean and decisive from cold and warm
  • ✓Check the frameless windows seal and drop correctly and inspect the boot for dampness on Sportback and Cabriolet models
  • ✓If it is a diesel, ask about DPF and EGR history because town-driven 2.0 TDI cars can become false economy
