Hey guys,

Looking for some advice here.

Just installed my Eventuri turbo inlets, and after a bit of driving I gotta CEL with the code P04FC - Crankcase Ventilation system performance.

Any ideas what may cause this? No coincidence that it just started after this install but everything seems to be connected properly.

Has anyone installed turbo inlets and had this issue?

One concern of mine is that I feel the turbo inlet on the driver's side connects to the engine a lot tighter than the passenger side, almost like a fitment issue where there's a tad of wiggle. The only thing keeping the inlets in place is a clip. Thinking this is where I will start my troubleshooting

TheGreatM8 Has just got he same CEL as well. Maybe there is leak at the connection of the tubes.

Almost exactly the same thing and circumstances except different code. Mine is 16050A, I thought the passenger side one was a tad loose as well so took them both off and re- connected 2 more times. I even throughly cleaned the rubber gasket/seal on both and the actual aluminum tube to the turbo housing.

I still get the code after all that. If I hadn't thrown them away I would try the OEM back on and see if that is indeed the problem.

As suggested by Tenac I'm going to try to replace the sensor and filter next.

But...Standing by to hear any more info...
Please share..

I agree with this might be the leak point, but with that said...It's just a tube feeding air to the turbos right? 16 inches in front of that tube we all put a giant un-restricted Eventuri orifice's to feed as much air as possible to those things..So more air should be better? It just doesn't make sense to me but everything sure points to that. In theory shouldn't you be able to run those turbos with no tube?

Most turbo cars have an array of sensors needed to keep things in line, so a intake leak or over pressure can throw codes for sure. I'm not that well versed in the S63 to know how they all work together but here is a typical list of sensors needed... Too me might be worth a call to see if they Eventuri ran into anything during their testing. If for some reason there is too much pressure or too less that will put out codes just not 100% sure which codes BMW would send out.

Sensor - Barometric Pressure.
Sensor - EGR Valve Pressure Feedback.
Sensor - Fuel Vapor / Vent Pressure.
Sensor - Intake Air Temperature.
Sensor - Manifold Differential Pressure.
Sensor - Map.
Sensor - Turbocharger Boost

Totally worth a test to go back to OEM if someone can.

Im going to check this toady: Maybe, just maybe the O-ring gasket was put in backwards. I don't remember picking a way it went in when I installed them.

Heres the install link that I didn't use....LOL. Talks about the way that O-ring must go in.

I'm fairly sure I put the gasket on correctly. I think the leak is coming from aluminum housing that doesn't properly sit flush on the turbo on the passenger side. Driver side is nice and tight, passenger side wobbles a bit. Checked my lines and everything seems to be connected, only thing we disconnect is the breather tube.

See pics for the not flush mount. There's a tiny sliver of space that I think is causing the leak.

Won't be able to put the oem ones on for a few days

[Tenac]

great find

[Da_BatMann_]

I cleared the code and wedged a piece of cardboard against the inlet tube and interchiller to tighten the gap a bit and the check engine came back about an hour later.

That being said, I'm not confident that what I did gave mea complete seal, still looked like there was a little gap on the bottom

[TheGreatM8]

I just re-did both sides just to make certain the gasket was correctly installed which it was.

I'm not confident that the area you're talking about sealing matters. It's a metal to metal connection area that just receives the housing. Further in is where the actual seal takes place at the O-Ring. The area where the spring clamp is does have very slight play, but thats what a spring clamp design is for, it only holds it from disconnecting. Not like say a radiator hose clamp would do. So I think that is by design and I bet our OEM tubes did the same thing.

Don't take me wrong, I would like very much for a simple solution.

Pics are with and without clamp

Great pics 👍 you may be right about it not mattering, that's just the only discrepancy I can find in the install. Everything else checks out, and given how much of a pain in the ass it was for me to take out the oem inlet pipe, I know that it was a much more tight fit than the Eventuri ones. It didn't wobble like this .

Wish I didn't leave my oem pipes at my brother's otherwise I could check it out today.

Did a 3hr drive today, didn't feel any performance issues or any bad side effects from this, yet.

[TheGreatM8]

I'll stay in holding pattern until you post anything else, as I don't know for sure what to check next. Seems way to coincidental now that you have the same problem... I had BMW service clear the code 2X and I cleared it as well. Seems to come back after about 40 minutes of driving for me.

[Da_BatMann_]

Yup, Will update after I install OEM pipes

Have either of you spoken directly to Eventuri?

I tried earlier. - No answer, But I'm Hawaii they are London.

[Da_BatMann_]

I haven't contacted them yet either, I will reach out tomorrow.

Shame with this CEL, because I do like the look of this product and I do feel that it makes the turbo sound a bit more pronounced in the cabin.

[Da_BatMann_]

I got a response from Eventuri.

"We are aware of this - basically the first batch of rubber gaskets were not made correctly. There is a gasket inside the breather block on the inlets.

We can send you replacement gaskets. All you have to do is remove the breather connector on the inlets and swap the rubber gaskets. The connector is held in place with 3 screws and nuts"

They're sending me new gaskets, you should read out to them and have them do the same.

[TheGreatM8]

Thanks man! I'm on it!

[TheGreatM8]

My new gaskets are on the way as well.

Love the fast response from these folks at Eventuri!

“I am sorry to hear that you received a check engine light code after fitting your Inlets.

I have asked for a new pair of the Inlet Gaskets to be sent out to you with DHL today.”

[Da_BatMann_]

I should be getting mine Tuesday, will come back with updates after install

Guys just read your notes. Just put the inlet tube and Eventuri intake on my car and received check engine stating a leak. obviously the increase in air from the intake to turbine. I have taken to dealer and they checked my work no leaks,
I will be reaching out to Eventuri myself tomorrow. Bryan 2022 M8 GC
