Reassuring points
Reliability- The `3.0 TFSI EA839` still brings proper fast-petrol character, with more flexibility and maturity than older, more demonstrative `S4/S5` models.
- The `S tronic`, `quattro` system and chassis electronics make this phase genuinely easy to use on long trips when everything is healthy.
- The `S5 Sedan B10` can remain relatively straightforward to follow if it keeps a clean dealer file, completed software updates and no doubtful preparation.
- On such a recent car, wear often shows earlier and more honestly than before: battery, tyres, brakes and software quickly reveal the previous owner's discipline.
