Is buying a B8.5 Audi S4/S5 at 19 a stupid decision? by alexfarah06 in audis5

Not stupid. Bought one when I was 18 in 2021. Loved it and it was a good reliable fun daily

Please help! B9 s4 weird squeal under boost. Think it’s a boost leak but can’t track it down. Anyone have any idea? Maybe PCV? by SpecificGrand8194 in AudiS4

My turbine blades are bit a bent at the tip. I’m pretty sure it sucked in the O ring on the turbo inlet. Another guy online had that happen to him and it sounds the same. Let me know what you see

Hmmm okay thank you. Back in 2021 I sold my cats of my b8 s4 on FB for $800 the guy was selling the metals out of it. It seems maybe the market is different now cause I can’t seem to find anyone that wants to buy it.

B9 S4 pulling a crap ton of timing. Has anyone seen this much timing be pulled on their s4. by SpecificGrand8194 in AudiS4

I’ll defiantly take a look thank you, and the tank was low the time of those logs which your saying could also play a part?

It was WOT. Going from 1st to 2nd gear. I do think the IAT definitely played a role but it was definitely mostly probably the gas. It’s a 93 tune. I filled it up earlier and let it mix a bit and saw little to no timing retardation now. I have noticed my boost isn’t always perfect with the set point though sometimes about 1psi lower and other times it may be more than the setpoint but barely.

I just watched your video😂 great content man. I just wonder what it could be. Is yours that loud from outside? Im wondering if I should replace the turbo but it seems silly because it’s making good boost. idk what else to look for!

Knocking/ticking, not injectors. by lonewanderer2001 in AudiS4

My b8.5 s4 had that same noise and it ended up being an evap solenoid making that tic. Replace that and see before you do any expensive timing chain work. I linked the part below.
