We go through the known weak points: oil consumption on pre-2019 2.0 TFSI engines and the revised piston sealing that fixed it on the B9.5, high-pressure fuel pump failure on TFSI engines and how to spot it at inspection, the S-tronic dual-clutch mechatronic unit that degrades past 80,000 miles without a documented fluid change, Virtual Cockpit dead pixels and partial screen failures on higher-mileage cars, the Cabriolet hydraulic soft-top pump — the number one expensive fault on the convertible, running $1,500 to $2,000 at a shop — carbon buildup on direct-injection TFSI units around 80,000 miles, MIB2 hard drive failure on first-generation B9 infotainment, the 2.0 TDI timing belt that most buyers overlook — and what happens when it fails — and the EGR and DPF issues that affect city-driven diesel examples. We also cover the difference between Quattro Ultra on base and mid-spec models and the Torsen mechanical center differential reserved for the S5 and RS5 — and why it matters when you're buying used. Whether you're actively shopping for an A5 B9, already own one, or you want to know which spec and engine combination holds up best over time, this guide gives you the full picture before any money changes hands.
