Mate, have to say - this guide is unbelievable, so helpful for me today. I’ve taken off my supercharger a few times and needed to replace my S/C I/C’s due to an epc issue. Not only were the part numbers a god send but it took me literally 20 minutes to replace them because of your guide!! Massive thank you from the UK and now more confident than ever to do the rocket cover gasket change from your video!! Keep up the good work mate and you’ll keep growing!!! How can I buy you a coffee or something without a super thanks on YT
Can i ask why you didn’t use an aluminium cleaner solution instead of the simple green. I know you mentioned it doesn’t damage them but maybe they do become a bit more brittle and then add heat on top of that. Cant they wear out faster?
So I’m doing a PCV change the cars at 68k miles so not crazy mileage but I figure I’d deal with everything I can while it’s off. You think it would still be worth while to clean the SC ICs since I’m already there?
I have a 2013 a7 took the supercharger out clean. Both inner coolers came out, shiny and perfect ordered new gaskets and still when I punched it out, the engine light came on, and the EPC light came on. My only final thing could be, and I think it’s that is my catalytic converter because they put new coils on a new spark plug, so I’m kind of like don’t know anymore. It’s frustrating.
Decided to clean IC on my wife's 2017 Q7 at 100K miles while replacing PCV and unfortunately the gasket on one of the coolers came out torn around O-ring portion. Unfortunately there is no inexpensive alternatives for aftermarket IC for CREC gen. engine at this point and it hurts to pay $700+ for otherwise perfectly fine IC. Wonder if it would be possible to split the existing gasket where it connects to an O-ring section and find similar size O-ring to slide over, basically making it two piece gasket...? Would that work or am I missing something? Why in a right mind someone wouldn't sell a replacement gasket? I thought we're concerned about the environment. Seems like shortsighted to say the least. Owning 4 Audis and being in love with these cars I do wonder, why some things designed to be so complex... The moment you decide to replace PCV you want to swap as many otherwise perfectly working parts as you can so you don't have to take a SC again, that is besides all of the one time use gaskets.
I was able to fix my original gasket using Q-bond, and the car is back on the road. However, looking back, I don't know if I would do it again. Examining how my gasket failed, it appears it might have been pinched at the factory because it was actually curled where it failed, and me pulling it back after about 7 years was enough to rip it due to how tight it is there.
@@AudiC7Owners I love your shop dude. Hopefully my wife and I will buy a house soon with a bigger garage. or even I would build my own little shop. That’s awesome to have so much space. I’m working out of a one car garage and it’s difficult
When I started the channel I was doing videos outside on a slab lol. This garage is the main reason I bought this new house. I love it. I just wish I could afford to finish it & make it look like a legit automotive enthusiast garage!
My best guess is that when the check valve in the breather hose that connects from your pcv to your intake fails, it allows oil vapors to get sucked in rather than only pulling in clean air to the pcv
@@AudiC7Owners Would the process not be the same? I'm literally planning on draining my oil tomorrow as I've taken off the supercharger today for the PVC swap.
He's referring to draining the oil inside the supercharger. It's actually a prices that needs to be done with care. If it isn't done correctly it can damage the supercharger.
@@AudiC7OwnersI was going to follow your video on changing my S/C oil tomorrow. Maybe you thought I was referring to the engine oil? I've really enjoyed your thorough videos.
Hey Cameron, for some people who might be doing this job in a future could you please verify if the coolant pipe screws need to be torqued at 9 NM..? CREC engine manual was showing only 5 NM.
@@AudiC7Owners I questioned 5nm because it seemed to be rather low and barely enough to compress new seals. 9nm seemed to be too much for this pipe though. When I put it together I went with 7nm personally. I pressurized the system before I put everything together and it maintained the pressure. Again, I just wanted to double check.
hey, stupid question. i’m looking to replace my cores in my supercharger and i’m wondering if the cores are the same? like on fcp euro it says sold individually and i don’t wanna order two lefts or two rights 😂😅
Hey man! Long time watcher. Love the vids. My 2012 A7 has been making a whistling sound after driving for 15-20 mins. I got the PCV valve replaced as I thought it may have been that but it hasn’t stopped the sound. Do you have any idea what it may be ? I know it’s a pretty general question but hoping you’ve experienced something similar 🙏
@@AudiC7Owners Hey, thanks for the reply. It seems to only really be when the engine is hot. It makes the sound even when just revving the car while stationary. But it doesn’t really make the sound when idle.
The Intercooler you have shown in your video have very nice breather screws on it, my original plastic ones are broken, where do I can get some of those you have in your Intercoolers?
Is it possible to clean the cores without taking them out like spraying concentrated simple green onto the cores through the holes beneath the supercharger and the rinsing them?
I got a cyl 2 misfire swaped coil and plug the cyl 2 plug looks like it’s coolant fouled. The misfire stayed on 2 . I was leaning toward the cooler . After seeing where the seams are on the cooler I’m not sure cyl 2 would get coolant from the cooler.
So how does the intercoolers even get air onto the fins to help with the cooling process? Seems like a very inefficient design and I think Audi should have gone with maybe a front mount intercooler.
Yes they can go in either side, but I wouldn't swap them if they've been used on one side already. Keep them on the same side after using them if you have to take them out for whatever reason.
@@AudiC7Owners ive got a cyl 5 misfire and i was watching your valve cover gasket vid and the part with your plugs made me thing to take another look at my old plugs and i also noticed i was down on coolant a bit too with no explained leaks and there was a bit of flaking on plug 5 and 6
@@AudiC7Owners my other guess was a partially clogged injector until i noticed the coolant. Mahle seems to be on back order through most sites for the cores unfortunately though. Im only getting a EPC and its only when im over 40% throttle
Clever bit of engineering to have the intercoolers right next to the supercharger in one package. Curious why Audi didn't have them front mounted, no space maybe?
No worries! Here is a fast breakdown: On our engines run on an Air-to-Water cooling system. There are two separate Loops inside of one coolant system. You fill your coolant in through your Reservoir and that fills up the two loops which are connected at a T-junction. One Loop is your engine, heater core, & the engine's radiator. The other loop is your supercharger coolant loop. The parts of that are a coolant pump, a heat exchanger which is located in front of your radiator, and then your supercharger which has two separate intercooler cores located inside of it. The coolant is pushed through the heat exchanger which uses air to flow to cool down the coolant. Then it goes into the supercharger intercooler cores which also uses air coming in through the intake to cool down the coolant even more. All of this is done to reduce the temperature of the air being pushed into your intake manifold. The cooler the air, the better the performance. This air temp is referred to as you're IAT's, or Intake Air Temperatures. Hope that helps
@Audi C7 Owners thank you, so the short is that the supercharger air is run through a water-cooled intercooler system. What kind of Temps can it achieve? It doesn't seem like you could get front mount or top mount intercooler temperatures but this is the first time I've learned about a water-cooled intercooler
It definitely isn't as cool as an Air-to-Air system. The car will retard timing if your IAT's go over 80C/175F and you will lose about 40% of your power. With the right cooling mods you can easily stay under this even with big performance upgrades.
I'm inspecting for oil leaks too rule that out, but I believe my breather tube that comes out of the pcv is broken... Rather the check valve on it is. Probably going to open everything back up to replace it and pray it works
@@AudiC7Owners @Audi C7 Owners International That was my issue on my 3.0T. Part looked pristine too. It's been a couple months now with no faults so I think I'm in the clear.

Did your intake flappers look clean? No orange or pink color?
I guess I was wrong. Learn something new everyday.
What are symptoms of failed supercharger intercooler cores and what would cause them to fail ?
I'm enjoying the detailed and detailed work. Please let me know the information about the green medicine
the 3.0T relocation kit is out of stock. Any ETA?
Great vid as always! What are your thoughts on a methanol injection kit to help with A.I.T's?

hello, good afternoon, a question where can I buy the intercooler cores for an Audi A6 tfsi 3.0t, thanks
Ecs tuning or fcp euro
Are the supercharger cores the same as the supercharger bricks people commonly refer to on these motors?
Yes
What’s the part number for the gasket on the entrance of the intercooler
hey, stupid question. i’m looking to replace my cores in my supercharger and i’m wondering if the cores are the same? like on fcp euro it says sold individually and i don’t wanna order two lefts or two rights 😂😅

So how does the intercoolers even get air onto the fins to help with the cooling process? Seems like a very inefficient design and I think Audi should have gone with maybe a front mount intercooler.
Directly from the intake
