2015 A8L 4.0 62700 miles. 12/23/2021 The vehicle has been diagnosed with turbo failure. No aggressive driving. Car purchased in 2019, always serviced at audi dealer (oil changed every 6000- 7000 miles).
Audi quote me with a 10K bill for this repair.
Well I guess I am one of the lucky ones. In early June, I had my local dealership check the condition of my turbos (my car was still under the CPO and the front suspension was being worked on at that time). All was good, but I felt like I had a ticking time bomb since my car has just over 70k miles. So earlier this week I decided to have my local (trusted) Audi indy replace the screen and associated items. I asked them to keep the screen for me and WOW, what a good decision. The screen was totally clogged (pics will come later today) and had a good sized rip in it. I'm confident the ripped opening kept the oil supply from being completely cut off. I feel like a dodged a bullet! At least now I can use my car in confidence and won't think twice the next time we have a long road trip.
BTW, the Service Advisor and I chatted about oil change intervals. He recommended that I do it every 5k miles and I agree.

I have done 5K OCIs on all the VAG cars and have never had any issues, tuned or not (after my A6). I made an executive decision oil changes are cheaper than bigger ticket maintenance items. Now some folks are dealing with 3.0T Q7s and oil consumption, especially on 10K OCIs but I haven't had any issues with 5K OCIs nor abnormal oil burning or anything else for that matter.
Good point! I cannot go 10k between oil changes without have a add oil anyway, lol.
yup. hoping you caught your clogged screen early enough. I have seen turbos not fair well even after a screen change/removal after a good number of miles. it also is not a bad idea to do the PCV valve when the technician is in there...
DD, how much did it set you back? Just wondering if I should do this as well, since I'm just south of 90k, no issues presenting (though they typically don't).
Just over $3k "out the door". Parts (PCV, screen, separator, gaskets, oil change, etc.), labor, and tax.
I am NOT in the habit of spending money on something that isn't broken, but made an exception in this case. My intention was to do it myself during the holiday break, but got sidetracked. I think the parts' cost was around $800-900.
Hi all! So, I just bought my first 4.0T. 2014 S8. It has 130k miles and the screen has never been cleaned. I checked the both turbos axle play (side to side and in/out) and the compressor wheel doesnt hit the housing but its pretty close. You can probably fit something there that has the thickness of a bible page, nothing thicker. In/out play is zero, cant feel it by hand. It seems that I have to check the screen (replace the valve under the screen and ofc new oil separator just in case) and maybe start looking for new turbos because the current ones dont have that much life left. My question is that because Audi have ditched that screen after 2016, is there any reason to update the screen to the never version vs remove it completely? Any thoughts?
There are a couple of YouTube videos where people have removed the screen altogether. It seems to work fine, but some of the owners claim that there might be an increase in oil consumption. Nothing scientific, just their impression.
My feeling is that if Audi went to the trouble to redesign a new screen (creating a new part number, engineering, etc.) then I should probably use it. Perhaps it helps regulate the amount of oil sent to the turbos?
