Platform guide · covers B8 and B8.5
Audi S4 B8
The B8 S4 is the supercharged one. Audi’s EA837 3.0 TFSI uses a Roots-type blower rather than a turbo, driving quattro through either a six-speed manual or the DL501 seven-speed S tronic. US cars run 2010 through 2016 across the B8 and B8.5 phases.

Phases
- B82010 to 2012First supercharged S4; last with the pre-facelift nose.
- B8.52013 to 2016Facelift B8 — same EA837 supercharged V6, last manual S4.
Owning and working on it
- Rated 333 hp and 325 lb-ft. The TFSI badge here means supercharged, not turbocharged.
- The B8.5 facelift kept the same EA837 and was the last S4 offered with a manual gearbox.
- The mechanical water pump is a known leak item on this engine. Access is tight enough that some jobs remove the supercharger for room, so budget real hours.
- The oil separator sits under intake plumbing. Plan extra disassembly time and confirm which revision your engine takes before ordering.
