18 S5 Sportback First fail part...P0299

[jonpark]

My Mods:
APR FMIC, FORGE BOV Dump valve, JB4, Injen CAI

This happened this morning as I driving to work for about 1hr.
Lost power, no boost, and was making whining noise.
Fault code is P0299

Googled P0299 and people said it probably faulty DV... but I already have upgraded to Forge bov.
Now I gotta try to put the stock one back on then test drive it...
I hope it is not the turbo itself....

Good luck man and report back on your progress.

I don’t know about the code, but my Forge Atmospheric Dump Valve never threw any codes, neither had any power problems. The only issue many of us noticed was very high IAT´s with Forge Valves, but that issue is now corrected with the new changes in installing it. Did you followed the new procedure too? Did you double check all your connections after installing it?
Hope this get fixed easily 👍🏻

Just swapped back to stock dv and it does the same...
Now it's more like turbo itself.... maybe the wastegate... I don't know.
but It does make very annoying whine noise whenever I press the gas pedal.
It gets louder as I press the gas pedal down harder.
It might be time to upgrade to different turbo...

Did you checked the hoses at the APR intercooler? Try Tightening the all hose clamps, just to be sure you are not having a drop in pressure and fail because of leaks at some point. If that’s ok, a visit to your dealer maybe the next step. Good luck 👍🏻

It is definitely the turbo...
It makes that noise from it...and little bit of smoke and oil leak in intake.

I think I'm just gonna use that as a hybrid turbo core.
Who makes hybrid turbo anyways?

on a side note, im not surprised to see youre running a jb4.

Care to elaborate?

Are you implying that the JB4 caused his issue?

Got a call from Audi Wilmington...it's a shot turbo and I'm at 53000 miles and they won't cover it...
I am very disappointed that stock turbo failed so fast even with jb4 at 19-20psi daily...
Well...I just ordered another used stock turbo to replace it and then I'm gonna send my broken turbo to get it hybrid set up.

What was the reason they wouldn’t cover it? Was the car flagged TD1?

Edit I misread the mileage- 53,000 is outside of the warranty limit.

I planned on building out my 18 S5 SB very similarly to you! I bought mine used 20k miles. Planned to mod a FMIC + JB4... should I be worried i will blow a turbo?? Thought these devices were manufactured to run fairly seamlessly on the B9 platform. Thoughts please!

if you are putting a used turbo on I would 100% recommend getting a proper tune

It seems you're tossing out implications about the JB4 causing the turbo to fail. It also seems like you're unwilling to back up what you're saying. If you have some useful information please share as it could help others, otherwise you're just stirring the pot.

@jonpark That sucks man sorry it happened to you. I just installed a JB4 and will be installing a FMIC as soon as it's not 100 degrees in my garage, so I've got some skin in the outcome of your situation. It doesn't make me feel good but I also know that the turbo can fail on a stock car at 53K miles. I've got confidence in George and BMS, this isn't their first platform and they've got a good track record.

At some point every tune and every piggy has been blamed for an engine failure of one kind or another.

Honestly, any time you tune any car you should consider the possibility of a failure because you're pushing it beyond the manufacturers specifications. Gotta pay to play.

[jonpark]

I don't think 19-20psi on stock turbo is too much....
I've ran much higher boost on WRX and never gave up on me.
I think it was just my luck.

[Hondaciviceg]

Was it important to change your FMIC when putting on a tune? I have recently ordered Catless downpipes and Intake from CTS and now looking around for a good tune as I know I will have an engine check with the DPs, would you recommend JB4? Or any other brand?

I would have a look at the DV. Maybe put stock first then Forge and see if you notice and difference in spool speed. If its more laggy with Forge then potentially there is a slight leak of some kind which might have caused the turbo to over spin to hit target boost. If not then I guess its one of those things and a trend will be created over time once there are more flash tunes which hit higher peak boost numbers so failure rate might potentially increase.

Already checked between Stock DV and Forge BOV. No difference.
There is zero boost. It is the turbo itself...

I mean when you get the replacement on.

Oh ok
But I think I'm gonna stick with stock bov or try a recirculating valve.

I’m pretty happy with my JB4. I’ve seen some numbers with the recent flash tunes and they are comparable to JB4. The benefit of JB4 at this time is that I can uninstall and go to MAP0 or MAP5 when using race fuel.

I saw a 10second s5 running JB4 on dragy ... my RS5 is nowhere near his numbers so I’m curious what settings he’s got or done to his car.

Are you asking me what setting I was on when this happened?
If so, I'm on map4 or sometimes map3.
I asked George before I choose the map based on the log that I sent to him.

Its a car fitted with a Eurocode SRM GTX35 hybrid turbo. Peaks at 28 from around 5500 and holds it to redline. He backed the dragy run up at the track yesterday making it the first B9 S5 officially in the 10's. Car is full weight, 94oct and runs on 20 inch wheels so not really set up for quarters so a massive achievement.

Why are comments being deleted in this thread? Turbo failure can happen in stock form, I've seen it.

Did you inspect the turbo? Are the blades damaged? Did it made contact with the housing? Is the chra hard to spin? That could help find out what happened. I don't know how many units BMS have sold for our cars but absolutely nothing indicates an higher failure rate when running the jb4 and if the turbo is a weak point, we will see them pop on flash tunes just as much.

My car is running 10's daily with the jb4 and methanol. Logs are very clean

Its a bit of a bad show they got deleted but at least they quoted. Normally if you throw mud around your hand gets dirty first.

I haven't inspected stock turbo yet since the replacement turbo hasn't arrived yet.... can't wait... they said just few more day until I get it...

[jonpark]

I have replaced stock turbo with an used turbo from Germany... Now it's back to normal...
But I spent $900 on another stock turbo and $250 in labor to put in.
Can't trust stock turbo now... I am sending my broken turbo to get it upgraded to hybrid set up.
