Frequently asked questions
Which Audi Q5 III engine is the most reliable?
40 / 45 TFSI (2.0 EA888 / 3.0 EA839) — Maint. Sensitive verdict. The petrols span the 2.0 TFSI (40/45 TFSI, EA888 Gen3 with 48V mild-hybrid — shared with the A4/A5/Q5) and the smooth 3.0 V6 TFSI (55 TFSI, EA839). The 2.0 EA888 Gen3 is robust (chain-driven, the Gen2 oil-burn long resolved) with the usual modern cautions — chain-tensioner, PCV, DI carbon — plus the 48V mild-hybrid system; the V6 adds its own complexity and cost. Both pair with the S tronic/tiptronic and quattro. A documented car with a healthy chain is dependable and refined. Buy on oil, chain and (48V/gearbox) service history.
