AUDI S4 BOOST LEAK | FAILED PCV UNIT?

Рет қаралды 532

Ай бұрын

I discovered I had a moderate boost leak so I took my S4 to the shop to investigate. We conducted some basic diagnostics, including a smoke test, and then finally replaced the PCV unit. Will this fix the boost leak issue? Watch to find out. Watch until the end to see some new under the hood bling.

If you own a B9 S4/S5 this is a mandatory youtube channel in my opinion.

I have a 2019 A7 and I replaced my PCV valve alone 3 weeks ago and I can swear up and down that it's made a huge difference in my acceleration. Especially my boost. It fills up easier, and also fills up slightly during each gear change until 4 or 5th gear I think.

@@midlifemods lol after seeing your video, I realized there is more to the PCV unit lol. I just bought the pcv crankcase. I'm at the dealership right now.

The 034 logo over his IE shirt LOL 😂… Also there’s a pretty easy solution to see if it’s the turbo, put a TTE810 in there and see if the whistle goes away. Basically the only solution IMO 😉

DUDE! Where were you when I needed you?! This video would have been so much better if you walked into the garage and handed me a new TTE810! HAHAHA! Maybe next video? :)

@@midlifemods you just have to move a few hundred miles up north sir. Surely we can find a TTE or two laying around at 034 👀 😆

Did you check the charge pipe connection on the intercooler? When I changed my intercooler out, I got a similar whistle once I tightened it down. It went away.

Not yet but that’s next on my list. Thanks for the tip!

@timmoran6280 Ай бұрын

Is there any way you are getting a leak from your connections to your intercooler? would a poor or loosened hose clamp cause a drop in boost? I know when I put my intercooler in I went out and got even heavier duty hose clamps and ran two on each side as I had the room and I figured I just wont eat that day for the weght reduction. Also with the interrcooler tucked right up against the grill if under boost it was the intercooler either a really small crack in a fin or a leak on that hose you might not even see the smoke as ambient air may make it dissipate if a minor leak. Maybe the charge pipes not tight to the throttlebody? Im not sure. I just know you from the group and are trying to brain storm ideas because I like your channel and you are always cool with people in the 034 group and hope you can get it completely sorted quickly. I bet even if your PCV valve was still good that the tighter fitting billet cap helps . Anyways, hope you get to the bottom of the mystery!.

Thanks man! I appreciate the brainstorming. I'm pulling off the bumper and grill tomorrow to do all the chrome delete stuff so I'm going to look at the charge pipes and intercooler closely to see if notice anything obvious. The good news is I'm not getting any low boost codes, so I should be fine for now.

No brother. Still trying to track it down. I ran the car pretty hard today and it performed really well with no codes. I still hear the whistle though.

Man it’s the hose, not the pcv unit itself. The hose can only be purchased with the stock inlet pipe. 034 has a video on that

@midlifemods Ай бұрын

We tested the hose. Maybe you didn’t watch the whole video, but I showed 034’s video in this. We did the hose valve test.

@shieric123 Ай бұрын

it's your ZF8 transmission whining? that's my guess. not a bad thing, I've heard some B9s with that, just treat it as a new supercharger whine

You think? Maybe. Could be the JXB Performance Driveshaft Carrier? Should I slap a "Supercharged" badge on the quarter panel? LOL! :)

@@midlifemods i think so? my B9 RS5 sounds like that once you get the transmission warmed up and start driving and ppl on the forums reported the same, it's a similar ZF so maybe? enjoy the supercharger whine in good health
