Hello all, my A6 has had the 24194 PCV code since the end of 2023, cleared a few times and it kept returning. I guess this is related with crankcase ventilation shut-off valve N548 being stuck open. However, I recently observed a separate code that seems related but not mentioned before. I am pasting the full scan and the separate module fault codes:

Any other possible issues besides N548 being stuck?
Thanks in advance!

Have you confirmed that N548 is stuck ?

Stuck Open ?
Stuck Closed ?
Disintegrated ?

What have you tested and how ?

Thank you for your response.

I have a hand-held pump with a pressure/vacuum gauge sourced from local hardware store chain. When I disconnect the rubber tube from intake before throttle body and connect to the pump while engine is off, I can blow air down the hose but unable to pull any vacuum, so my assumption is that the N548 valve is stuck open as from somewhere I read it should work as a check valve. If I spray one or two shots of any organic solvent-based lubricant, then I can pull the vacuum and held at -25 in Hg. With the engine idling, the vacuum gauge reading is somewhere 4-5 in Hg, and from the SSP 624 I read the crankcase vacuum should be 150 mbar / 2.17 psi / 4.43 in Hg so I assume the connection down to the crankcase has no major leaks, thus N548 is not disintegrated. After switching off the engine, the vacuum cannot be pulled again.

Plus, if I use the Output Test to manually command the valve while the engine is off without spraying anything down the hose, there is no obvious difference whether it is on or off. Though I can't really recall how it performed after I sprayed and then commanded it to Open/Close. Maybe I should try that again?

Cheers

Vehicle needs the entire breather in the valley replaced. Known code and TSB from audi regarding this code and issue.

TSB:


Many replace just the membrane. Personally If i'm going that deep to do it, i'm not slapping on a bandaid. I'm changing the whole breather.

For sure change the whole breather! And O.E. part from a good place. No cheap shit!

Good Luck

In this particular case I would only be buying a factory part from the dealer as it will have the most up to date part with the right spring for the pressure reduction. Many aftermarket units may cause the same fault because of a different spring being installed causing higher crankcase pressure. Often is the case with aftermarket parts.

Agreed and appreciate for all the input. According to the TSB you mentioned, currently I had no CEL or noticeable noises yet. I've also seen these bulletins before:
https://static.nhtsa.gov/odi/tsbs/2020/MC-10177763-0001.pdf
and warranty extension

I previously brought this thing up at the dealership to check if my car was covered before this code first showed up and they told me unfortunately the warranty key U38 did not apply to my vehicle so if I was concerned then I'd have to pay myself. In late 2024 knowing this code was present and I asked how much for them to do the PCV job and they told it was ~$2.2k for an S4 currently sitting in the shop and could be more since I had the extra port injection. Ouch! And unfortunately I do lack of the space and time to do the DIY repair myself. Oil consumption was ~0.7L/6000 miles for the previous OCI. Measured crankcase vacuum at idle (4-5 in Hg) is within the range specified in SSP 624 (150 mbar) when I connect my hand pump similar to the VAS 6213 to the breather connection upstream of throttle body.

This fault has been in the vehicle since 2023. Audi Cicero scanned the vehicle back on 05/30/2023. Fault code was stored in vehicle at that time. Correct U38 does not apply to this vehicle, but depending on emissions. It could of possibly been covered under 7/70 or 8/80 federal emissions or california emissions standards, although I am not certain of that.

I bought this car May 6, 2023, and I wasn't really aware of the presence of this error code until I got VCDS to change my rear brake pads late 2023. The freeze frame at that time was saying Dec 10 2023 if I remember correctly however cannot double check due to me accidently uninstalled VCDS while trying to update it and lost all the previous scans sometime last year. The late May 2023 visit was to have them replace the armrest bracket on the center console and fix the bumper stop on rear shock, which the selling dealer reimbursed me, but I didn't recall being informed about the PCV code at that time. And at this time even if the warranty key was applicable, it had been more than ten years from the car's in-service date in November 2015, and my car never had a CEL/MIL since I purchased it.

So if I am understanding correctly, there are chances that:
1. The breather hose with N548 is faulty (including the elbow piece in TSB #2060259, replace w/ 06E 103 207 AR?)
2. The rubber membrane of the oil separator module is perforated (replace with 06E 103 772 H kit?)
3. The entire oil separator module failed (06E 103 547 AF?)
will need to be fixed/replaced?

You can do any one of those items yes, just know that there is a good amount of work to get it done and it's not a job you want to be doing or pay for twice.

Yes I understand the amount of work will be quite a bit and probably will get the t-stat done at the same time while the coolant drained and charger removed. I already had the water pump replaced by an indy shop last November with coolant leaking onto the belts.
