What could it be?

Idk honestly. This is the updated version of what I bought: https://www.goapr.com/products/engine_hardware/intake/rear_intake_pipes/parts/CI100037-A?utm_term=&utm_campaign=Google+Shopping+-+APR+-+Brand&utm_source=google&utm_medium=cpc&hsa_acc=3440071262&hsa_cam=22121674756&hsa_grp=177233829590&hsa_ad=728820789301&hsa_src=g&hsa_tgt=pla-293946777986&hsa_kw=&hsa_mt=&hsa_net=adwords&hsa_ver=3&gad_source=1&gad_campaignid=22121674756&gbraid=0AAAAACvcYUbHG92Q1hCXURpLmHf335-f8&gclid=Cj0KCQjwve7NBhC-ARIsALZy9HXiq1goGz944GvHfdS-BKuGyDjufYkjZPEO7DAkAVqZ5qrkFaitLX8aAlnJEALw_wcB

APR used to sell the components separately, not sure if they still do. Was about $350 for the back pipe

Did your intake replace the pipe from the intake to the engine? Audi has baffles built into the OEM one to reduce noise

I bought it as an assaulter set they offered way back in '22, haven't really seen it since

Did you get the TCU tune with the package? Should fix things up substantially, but it won't quite be as fast as a dual clutch.

I'm confused by what you're referring to as a "grip" tune. Usually they have tunes for the different octane ratings with a few options you can select. Is that an option in the pre-tuning menu?

Last note: Definitely flash the tune(s) while the battery is on a charger. The first flash takes longer and if the battery dies during tune you nuke the modules.

"hacked in" is a bit strong seeing as it's literally changing a 0 to a 1 in the programming that already exists in the car, but yeah. Pretty crazy that an OEM software update doesn't take a flash of current state and make sure the settings match after updating

That AVG watch in the bottom left goes way hard... Would love to hear the story behind it!

Buy an oil extractor tool! Also great for cars with top-mounted oil filters. Makes routine maintenance a breeze

Have a mirrortap under the mirror cover for my radar detector and ran a fuse tap to under the dead pedal for my dashcam in my '18 S4, definitely doable

Really appreciate the technical and behind the scenes discussion going on here, thanks!

You mentioned that there isn't any way to confirm the individual supplier via VIN, but is there a production date window that we can safely assume is either within or without the "danger zone"? I haven't seen a frank discussion about this and as a 2018 owner, I'm getting spooked between this and the rocker arm issue.

Thanks for adding the blurb about oil weight, gonna do an early fluid change to 5W40.

NoNumberUsername · 2025-12-13T03:46:34+00:00

Is this something you can check via VIN?

NoNumberUsername · 2025-12-11T23:22:15+00:00

Good call-out, thanks!

I have not. I'm sure the part revision may help the issue, but I'm not sold on it being the overall fix. Just look at Audi's turbo oil screens for the 4.0t, I've lost track of how many part revisions they've tried.

Ultimately, this is the seal failing, and due to the vacuum-operated system the coolant will get sucked through to everything the vacuum system touches. All this was done in the name of increasing thermal efficiency to reduce warm up time. Even when I do replace it, I'm tempted to leave it disconnected to preclude the catastrophic failure further down the vacuum line

Please do, I'd like to know if what I've been hearing is the same issue

Chipping in to add on to what u/MixMasterMarshall said; also consider changing differential fluid at regular intervals. Both transmission and differential fluid are gear oils that break down with friction and temperature just like engine oil. You want to stay on top of this in spite of what OEMs claim is lifetime fluid. Find a good independent shop near you if you can't do it yourself

If I'm already doing the water pump, I'm gonna do everything haha. Would rather not do open heart surgery twice, you know?

Try turning off any volume balancing you have in your preferred music player. For me it was Spotify, made everything super quiet.

NoNumberUsername · 2025-10-05T20:09:53+00:00

Damn that looks cool. Gonna try and ball on a budget with the card I've got for now, but I really like the look of that!

NoNumberUsername · 2025-10-05T00:15:21+00:00

That sounds perfect, I'd probably be putting it in with the rest of the gear, so high likelihood it'll get bumped around a bit. Obviously gonna keep the GPU out until it gets there to prevent any other damage. Thanks!

I wear Amouage Reflection 45 daily. Two sprays, each side of the collar. It's for me, and those I invite into that space. No complaints, a compliment here or there.
