Cam, the only fault I find in your approach is the use of "electrical tape" . It is not going to last very long. Have you considered using heavy-duty glue-filled heat shrink tubing instead? As a broadcast engineer, I have used both in long-term, high-heat applications, and the shrink tubing ALWAYS comes out on top. We're talking still in situ years later, vs even the best e-tape failing and unraveling after a few heat cycles. E-tape is meant to be used as an installation aide, not a long-term leave-in-place item. Just my .02
He could use super 88 plus which has been for high temperature. Also, he can just use rubber electric tape. That would be better probably for for the braided line. I believe they come for compression. Not style that can go over the top. Maybe machine a couple parts. Sorry. It's Barb, it'll be threaded. Therefore, you can just use the braided black lines.

What’s the new crankcase vacuum measurement with this external PCV? B8 S4 ones are either 30 or 150 mbar depending on PCV revision and ECU updates. This is important info missing from this video.
Also, FYI, on the new external PCV, you could use the OEM vent tube ends that clip in place on one side as that’s what it’s designed to take and on the other side, it would be nice if Merc would make a new aluminum female to barb hose adapter that accepts the the bottom port of the PCV to be inserted in at an angle. That port has a ring seal around it and also is keyed to go into a factory port like that. Would make for a super clean install and OEM finish without all the junky JB Weld DIY stuff and zero modification of the PCV should you ever want or need to swap that out entirely rather than just the guts. It’s definitely something to seriously consider to make the install clean as hell. 👍
I love this. Our CREC engines are dying because of poor crankcase venting. The crankcase is only venting from one bank, instead of 2 banks like the earlier engines. I am looking to get this relocation kit and top cover for the second bank with an outlet for ventilation for bank 2. I am curious if the ECU will throw errors for pcv. We also have a n54 valve on our engines, so that might be a doozle. Kindly reach out so I see if we can work together on fixing the oil consumption issue on the CREC engine
Awesome stuff, this is a game changer. Are you planning on making a DIY for the upper timing chain tensioners any time soon? I heard you can change those with the engine in place in the C7 but there are 0 guides online that discuss that
The end that comes off the new spider hose will connect to the new pcv so you only need a 19mm 90 degree barb and some hose. The other side of the pcv is a 14mm hole so you can tap that and match that to the catch can.
Excellent video as usual from you, only one thing that is confusing me! You have replaced the OEM plastic PCV with an aluminium one from an older model car and installed a separate relocated PCV, but you also put a PCV valve back into the new aluminium housing under the super charger. Why fit 2x PCV’s, and couldn’t this still go bad meaning you have to pull the super charger back out in the future?
The Metal Valley Pan under the supercharger is just that. There is no pcv in it. The plastic piece that is on it is an oil separator (think oem catch can). These rarely have any failures. The only pcv is the relocated one 🤘🏻 Thank you for the kind words!
Yeah that was what i was thinking of too. Why not just remove n bypass the Stock Oil Separator and direct to a Catch can from the Crankcase Inlet/outpipe?
I ordered the kit from Merc Racing a few weeks ago. Got an email back saying some of it is on backorder with no eta on those parts. Within a few days I received everything I ordered. Ordered a few other items from FCP Euro some off Amazon like injector seals, aluminum oil filter housing, oil filters, and I got an aluminum coolant (water) pipe with O rings. The one that comes out the back of the thermostat. Now I just have to put it all back together.
This is definitely something worth considering! In addition to these changes, what other items would be suggested to do while you already have supercharger pulled?? Thermostat? Carbon clean? Cat replacement with down pipes, etc??
I just bought a 2012 mythos Black A6 and your channel has been very helpful in learning about this new chassis, and some of the things I need to do to make this a very dependable ride! Thank you!
Man what an amazing tutorial! Congrats!! Wish I could do this to my Q7 but the Intake sits on top of the supercharger and the lines ran a little different, really not in the mood to mess with that and screw something up. Congrats!
I love the content and direction here (fantastic videos), but I'm struggling with MercRacing at the moment, I ordered the kit on June 4th along with everything else on your list to relocate my PCV system and upgrade to the 3.2 manifold (also doing intercooler bricks while the supercharger is off), I have the catch can installed in my S4 and have located the spot for the diaphragm breather, and have it all ready with the connection JB Welded and black taped into place (the links were extremely helpful). I've watched all the videos, and ordered and received all the gaskets and O rings for everything, and feel fairly confident I can do this. I emailed Merc Racing asking for tracking info, as the order email still read "processing" and also the very first thing I ordered. The package came today (6/17), but is was missing the throttle body spacer gaskets and the longer bolts for use with the stock throttle body... so another contact email sent through their sight. I'm going to rewatch everything this week to make sure I have the process fresh in my head, hopefully I'll be able to start next weekend. I had hoped to have it complete by now.
Why couldn't Audi do this? Oh wait... then the Audi dealers couldn't charge $2,500 to do a PCV replacement AND a bunch of extras. Also you said the whistle is normal on the diaphragm, but isn't that one of the symptoms of a bad diaphragm? I had a whistle on mine, but not high pitched like the videos I've seen, but more noticeable on defrost. I was hoping it was not something in the vents b/c not much I can do to fix that. Will see is the PCV body replacement fixed it or will it be a "phantom" whistle I have to deal with for the life of the car. That will be frustrating if so.
I have a B8.5 S4, but I'm learning so much from your videos, so thank you. I will be doing a lot of maintenance soon and getting myself comfortable with the task by watching and rewatching your videos. I did notice you have the oil pressure check valves. Can you touch on them or is there a potential video coming? I've researched throughout the forums, and some say it helps with chain rattle, while others say it is not really worth it and just place O-rings on the plugs.
Absolutely amazing guide, I am doing all the research I can before buying a B8.5 S4, and this is definitely going to be among the first things I do along with a cat delete as preventative measures for the engine as soon as I get the car
Really excited to see if this works for the 3.0t CREC. Also curious if removing the CREC Supercharger is a different process, I have yet to do it but there are so many videos on the 3.0t I'm confident if it is the same I could do it.
@MystElectric there is a flat piece that has connections on the back of the Supercharger that has to be removed on a crec. I found it out when I couldn't get my Supercharger up after following his video.
Great vid. Looking forward to doing mine in a few weeks. Just a thought … would it not be possible to get an AN10 fitting with a smaller thread diameter to save having to do all the filing in the PCV fitting ?
There is a kit from mercracing for all the pieces you need to make this a bolt on job, but you still have to source other parts outside of that kit to complete this.

Quick question here. I’ve got a coolant leak I can’t narrow down quite yet. I pressured my coolant system to check for leaks and it dropped real quick but no visible signs of leaking. All my research so far leads me to believe it’s pooling under the supercharger where the coolant return pipe is. I’ve seen a lot of people saying to check there first but I’m apprehensive to take the supercharger off if there are some parts known to break. Any advice on what I should get before taking the supercharger off and anything else that would be a good idea to replace while under there? I have a soft code for PCV and I’m thinking breather hose and/or the diaphragm but I’m not sure how easy those are to replace while under there. Thanks in advance!
If you are pressurizing the system & song coolant without seeing anything leak then your pcv is likely cracked & you free mixing coolant into your engine oil. Drain your oil & check it. Having a pcv code means you're pcv diaphragm is shot anyways so you need to address all of this quickly
Intermittent code P052E00. Looks like I’ll be ordering some parts this afternoon 😆 One thing I did notice when pressurizing the system was that I could hear the air seeping out almost sounding underneath the supercharger.
Really cool video! Def. adding to my list of mods for my project B8.. Great idea and will probably do when I have the SC off the car.. Makes so much sense for this known crappy valve system :)
Justo el vídeo que estaba buscando Está será la primera modificación que le haré a mi c7 Para mí suerte tengo exactamente el mismo modelo y es fácil seguir los pasos Tienes un seguidor más ➕
Serious question...why didn't you just get a new breather check valve hose from fcp instead of using the oem one...Im asking cause I did a pcv replacement from fcp euro along with new hose etc but I'm getting a pcv code p052e00...I threw the oem away not thinking od need it. MYbe I should've kept it. But couldn't wait on the pcv relocation kit which has Been pre ordered for 3-4wks had to have car up and running for work. Any info on if a new check valve can fail? Or how do you check it
I wish I watched this video earlier. My coolant is mixing straight into the oil and I already put a 2k deposit on a new motor🤦🏽♂️ I’m definitely checking the pcv before I pull this motor out has 247k miles I put on but still runs strong.. other than fluid mixing.
Isn't it funny how it takes us normal people to fix Audi's over engineering on some of these things? It's like this PC v. And the thermostat and the water pump should all be located on the top. Front or outside, easy, can't speak. As we know, they're gonna fail every single time, maybe even multiple times
I have a 2013 A6 3 liter 310 hp vehicle with the same engine and the engine light with the code P0420 is constantly on. I add catalytic converter cleaner, it goes off for a while, then it comes on again, but there is no problem with performance and fuel consumption, it does not burn oil, but I am not sure if it has anything to do with this issue. .
@@AudiC7Owners But only the light has been on for about 7 months, P0420 but there is no other negative situation. What kind of problems will it cause if I leave it like this?And should they both change at the same time?
i have audi a6 3.0t , It reduces the oil of the engine very much without my car having smoke or leaks, for example, it reduces 1 l of oil in 200 kilometers while I put a lot of pressure on my car What is the reason for this reduction? And what's the solution? I live in Kurdistan I can't reach good people in this field
Don't make my mistake... I bought all these parts and took apart my 2016 A7, only to realize this kit only applies to C7 not C7.5. Our facelifted models use dual port injection and are not compatible with this earlier vintage valley pan conversion. Wasted a lot of time. Made the best of it by replacing PCV, water pump and thermo, while I was in there.
1) this is the first line of the description of the relocation parts kit on Mercracing's website: "**CREC & C6 A6 ENGINE COMPATIBILITY UNKNOWN**" 2) having pointed that out, we have had Multiple people with the crec engine complete the relocation. You have to modify the plastic oil separator that attaches to the metal valley pan to fit. There is an entire post about this on the relocation Facebook group for anyone interested.
@@AudiC7Owners that's fair. Being new to platform I had non-idea what crec meant. It's on me. Haven't been on FB since 2016, also on me. Is info posted anywhere else? I am in there now and would love to finish the job.
@@AudiC7Owners Understood. I would like to thank you for so much excellent content. I ended up buying tons of parts from FCPEuro, 034, MercRacing, and was able to do all the installs myself thanks to your DIYs. Thorough and clear explanations, good camera work, just perfect. I will bank up the PCV relo and catch can parts until I have cause for pulling the SC. Again, much appreciated!

Yes they have but they have to modify the plastic oil separator that attaches to the metal valley pan to fit. There is a post in the Facebook group about it
Hello guys, can someone tell me are c7 2012 3.0 TDI Quattro paired with 7 speed automatic transmission reliable and are there some things that I should look for when buying? Thank you
Very good cars. Have the same one for a year. So far only issue I had was overheating. Found out a coolant hose was cracked underneath supercharger. Replaced and no issues. Expensive to maintain
Has anyone had luck ordering this kit lately, I ordered in December but have not received any confirmation. Getting no replies to emails either. Just waiting with my car in pieces right now.
@AudiC7Owners Sorry, didn't see on the merc site when I ordered. Just saw that orders would be processed in January. Still excited to get my car up and going again, thanks for the info.
This is such a good informative video, I’m UK based and need to do my PCV asap. Not too confident doing this myself as I’ve only owned the car 2 weeks but I think even if I wanted to do this I’d struggle as I won’t be able to get the parts from these companies here in the UK. It would be good to know if there are any UK suppliers that have approached you though
@@AudiC7Owners ah that’s good to know. Doesn’t seem like there are many specific shops/garages that specialise with these 3.0tfsi engines here in the UK that I’ve found. Think I’d struggle asking a specialist to do this relocation, unless I try do it myself :/
Is the spider hose not supposed to be screwed into the metal valley pan? It has what looks like a hole for it to be screwed down. Is it just kept pressed in by the supercharger?
@@AudiC7Owners I went through every one of your shorts and can’t find the short about it. Do you know what kind of bolt you put in or what the part number for the OEM bolt is? Would one of the bolts used to screw the new metal valley pan down work? I’m leaving for vacation today and will only have two days after I get back before I have to drive 1000 miles to university so I’m hoping to have the bolt ready to go for a quick install when I get back.
Great stuff, very impressive. I’ll have to wait for the plug and play version, don’t trust my cutting and JB welding skills🙈😂. This will probably be one reason for keeping my B8.5 S4 a bit longer 😊
Haha I understand. But the piece you have to modify is only about 15-20$. You free buy two so you have one to choice on. Then you would already have an extra diaphragm to have in case yours ever tears. Win Win! 😂
@@AudiC7Owners oh I forgot to add…..I’m on the southern tip of Africa, South Africa to be precise. By the time we get parts here, the 20/30$ becomes closer to 50/60, due to our week currency and ridiculous shipping cost. I’ll be following this post/vid very closely
This kit does NOT work on a C7.5. We have dual port injection (as opposed to direct injection) and a very different PCV. You can use this video to help you DIY replace your PCV, as well as the one by FCPEuro, but don't buy these parts expecting to put a catch can on your C7.5 (or C8.5).
It actually does work, but you have to modify the plastic oil separator that attaches to the metal valley pan to fit correctly. We have had multiple CREC vehicles do the relocation.
I didn't read through all the comments, so please be patient. Did you ever find someone who did the relocation on a later model engine. I have a 2018 A6, 3.0T. I was wondering if it would work.
@AudiC7Owners , thanks. I guess I'll have to look around the internet to see if someone has done it and what it takes to make it work. Do you happen to know a link to someone who has done the CREC pcv relocation?
@@nickrojas7185 Join our FB Group about the PCV relocation. I have a post pinned to the featured posts about it in there. Link should be in the description.
@@AudiC7Owners The bad news for these engines is that the pcv system is built into the valve cover! This necessitated replacing those two V 6 covers and they cost around £500-600 in England only the parts! This 3.0 TDI engine is one of Audi's strongest!
what about using teflon tape around the end of the AN fitting that's going inside the larger of the holes on the PCV for a tighter fit? or do you think it will get too hot?
i want to buy this kit so badly but i dont know anyone to help me with this. I am too scared of breaking or fucking things up and my car has been sitting.:(
@@AudiC7Owners Midwest in wisconsin. We don’t have very many Audi mechanics at least right where I’m located and it’s been incredibly stressful the last 2 weeks w/o a car.
@@AudiC7Owners haha I’ve watched most of the series. My issue is having tools and the knowledge of this specific car as a whole. Not sure if it’s able to be ran in it’s current state if it’s going to end up damaging it vastly more or not. Will definitely look into some clubs or something around me. I appreciate it 🥺♥️
How much pressure is under the supercharger for the plug underneath? Could you use a rubber freeze plug (the type that tightens with an internal bolt)? How about a hard metal freeze plug inserted? Seems like any of these DIY options would eliminate the need for a special part only available at one or two places. Thoughts?
Just buy the mercracing plug. It's extremely affordable for piece of mind. I will never recommend a plumbing plug for something like this. If you choose to go that route, do so at your own risk
Cam, the only fault I find in your approach is the use of "electrical tape" . It is not going to last very long. Have you considered using heavy-duty glue-filled heat shrink tubing instead?

One small piece an inch or 2 of shrink wrap or a small zip tie to terminate the tape and it's fine. It's what the factory uses for a reason
It’s NASCAR electrical tape, it’ll be fine

At present I am not as my guides are working great (knock on wood).
i’m currently changing my pcv. i can’t wait till y’all make a full on kit so i can just bolt on an go 🙌

Any updates for MERC adapting this mod to the CREC?

Hi thank you for the videos, is the kit available
Yes, but a lot of the parts are backordered. Hoping to have some in stock on the mercracing site very soon
I ordered the kit from Merc Racing a few weeks ago. Got an email back saying some of it is on backorder with no eta on those parts. Within a few days I received everything I ordered.

You are a genius. Any vehicle equipped with an Audi supercharger seems to be possible.Thanks.
Thanks man! I couldn't have done it without those that did it before me & the help of MercRacing in developing the diy parts.
This is definitely something worth considering! In addition to these changes, what other items would be suggested to do while you already have supercharger pulled?? Thermostat? Carbon clean? Cat replacement with down pipes, etc??

@@rolfisfernandez4340 thanks man! They are definitely worth doing. I don't have a video yet, but I will soon
I do have a question. Why return the pcv to the intake instead of just venting to the side of the engine? Intake would love breathing cleaner
Because it is a pressurized system. Venting to atmosphere would cause it to operate poorly.
Catch can cleans the return well though
Thank you for clearing that up for me Cameron. Just me not listening properly.
No worries!
Nerds 😂
Is there a timeline for when a full bolt on kit might come to market?
This is specifically discussed in the video

For anyone still wondering this relocation has been confirmed to work on the 2009-2011 c6 3.0tfsi
I was just searching the comments for this! Thank you!
@@Farmerdabrown85 no problem it worked great for me
Did it fit exactly the same way as in the video or did you have to change some things
@@confetty5151 only difference is location of catch can couldnt behind headlight like in this vid so i put it by passenger side strut ,mount
Thanks for all you do man!
Thank you!
Will this work on 2011 Audi a6 3.0t?
Yep!
Work with the crec ?
Hello, I need help. I have audi q5 3.0 tfsi pulling air from the oil filling cover. I replaced the pcv valve and still the same problem. Please help.
@@محمدالعجمي-ك1ف you mean the valve cover? Sounds like you need to replace the gasket. I have a video on that too
@@AudiC7OwnersNo dear, the sound of drawing from the oil filling cap
Thanks me have one Is
Really excited to see if this works for the 3.0t CREC. Also curious if removing the CREC Supercharger is a different process, I have yet to do it but there are so many videos on the 3.0t I'm confident if it is the same I could do it.
There are some very small variations with vacuum connections I think, but overall should be very very similar
@@AudiC7Owners Good to know! I just joined the facebook group and so far they have been very helpful and welcoming! Seems like a great community!
@MystElectric there is a flat piece that has connections on the back of the Supercharger that has to be removed on a crec. I found it out when I couldn't get my Supercharger up after following his video.
@@MystElectricwhich group? I got a CREC too and want to do this PCV recloation
i definitely want a kit. great vid
would this work an a c6/2011 a6 3.0t?
Yes
Any idea if/when the MercRacing kit will be back in stock? Trying to do this to my B8 S4.
Great vid. Looking forward to doing mine in a few weeks. Just a thought … would it not be possible to get an AN10 fitting with a smaller thread diameter to save having to do all the filing in the PCV fitting ?
what a genius idea!
06E103217M - Will this vent hose work on C6/C7? This is the AUK chassis code.
would this work on a 2011 3.0t a8l?
Yes
Is there a kit created for this process yet ??
There is a kit from mercracing for all the pieces you need to make this a bolt on job, but you still have to source other parts outside of that kit to complete this.
Hello
Please tell me where’s the fuel temperature sensor located on Audi a7 3.0 TFSI
Best regards

Quick question here. I’ve got a coolant leak I can’t narrow down quite yet. I pressured my coolant system to check for leaks and it dropped real quick but no visible signs of leaking. All my research so far leads me to believe it’s pooling under the supercharger where the coolant return pipe is. I’ve seen a lot of people saying to check there first but I’m apprehensive to take the supercharger off if there are some parts known to break. Any advice on what I should get before taking the supercharger off and anything else that would be a good idea to replace while under there? I have a soft code for PCV and I’m thinking breather hose and/or the diaphragm but I’m not sure how easy those are to replace while under there. Thanks in advance!
If you are pressurizing the system & song coolant without seeing anything leak then your pcv is likely cracked & you free mixing coolant into your engine oil. Drain your oil & check it.
Having a pcv code means you're pcv diaphragm is shot anyways so you need to address all of this quickly
I wouldn't drive the car until you sort these issues.
@@AudiC7Owners so new pcv, breather hose… the works?
Intermittent code P052E00. Looks like I’ll be ordering some parts this afternoon 😆 One thing I did notice when pressurizing the system was that I could hear the air seeping out almost sounding underneath the supercharger.
Pull the supercharger & take a look
i had to do the pcv on a customers 13 sq5 yesterday it was an 5-6 hr job. thankfully i had no issues
Really cool video! Def. adding to my list of mods for my project B8.. Great idea and will probably do when I have the SC off the car.. Makes so much sense for this known crappy valve system :)
Great guide! Now I know why my IE catch can never fills up. I'm adding this to my list of preventative maintenance to do on my S4.
Hi, great video.
Any info on any shops or anywhere I can have it done on the East Coast?
fantastic!😎
Justo el vídeo que estaba buscando
Está será la primera modificación que le haré a mi c7
Para mí suerte tengo exactamente el mismo modelo y es fácil seguir los pasos

Serious question...why didn't you just get a new breather check valve hose from fcp instead of using the oem one...Im asking cause I did a pcv replacement from fcp euro along with new hose etc but I'm getting a pcv code p052e00...I threw the oem away not thinking od need it. MYbe I should've kept it. But couldn't wait on the pcv relocation kit which has Been pre ordered for 3-4wks had to have car up and running for work. Any info on if a new check valve can fail? Or how do you check it
The oem check valve hose didn't fit/work on the spider hose I'm using with the relocation.
P025E can be caused by a faulty pcv or check valve.
I wish I watched this video earlier. My coolant is mixing straight into the oil and I already put a 2k deposit on a new motor🤦🏽♂️ I’m definitely checking the pcv before I pull this motor out has 247k miles I put on but still runs strong.. other than fluid mixing.
That's impressive mileage!
Isn't it funny how it takes us normal people to fix Audi's over engineering on some of these things? It's like this PC v. And the thermostat and the water pump should all be located on the top. Front or outside, easy, can't speak. As we know, they're gonna fail every single time, maybe even multiple times
The thermostat isn't a fun job, but the water pump is fairly easy to do. Don't even have to remove the supercharger
I have a 2013 A6 3 liter 310 hp vehicle with the same engine and the engine light with the code P0420 is constantly on. I add catalytic converter cleaner, it goes off for a while, then it comes on again, but there is no problem with performance and fuel consumption, it does not burn oil, but I am not sure if it has anything to do with this issue. .
You have a failing catalytic converter
@@AudiC7Owners But only the light has been on for about 7 months, P0420 but there is no other negative situation. What kind of problems will it cause if I leave it like this?And should they both change at the same time?
Watch this, but yes I'd suggest replacing them both

@@AudiC7Owners 👍 Thanks
i have audi a6 3.0t , It reduces the oil of the engine very much without my car having smoke or leaks, for example, it reduces 1 l of oil in 200 kilometers while I put a lot of pressure on my car
What is the reason for this reduction? And what's the solution? I live in Kurdistan I can't reach good people in this field
Check out our oil consumption video. That covers the majority of oil consumption/leak issues.
Don't make my mistake... I bought all these parts and took apart my 2016 A7, only to realize this kit only applies to C7 not C7.5. Our facelifted models use dual port injection and are not compatible with this earlier vintage valley pan conversion. Wasted a lot of time. Made the best of it by replacing PCV, water pump and thermo, while I was in there.
1) this is the first line of the description of the relocation parts kit on Mercracing's website:
"**CREC & C6 A6 ENGINE COMPATIBILITY UNKNOWN**"
2) having pointed that out, we have had Multiple people with the crec engine complete the relocation. You have to modify the plastic oil separator that attaches to the metal valley pan to fit. There is an entire post about this on the relocation Facebook group for anyone interested.
@@AudiC7Owners that's fair. Being new to platform I had non-idea what crec meant. It's on me. Haven't been on FB since 2016, also on me. Is info posted anywhere else? I am in there now and would love to finish the job.
Unfortunately no. Just in that group
@@AudiC7Owners Understood. I would like to thank you for so much excellent content. I ended up buying tons of parts from FCPEuro, 034, MercRacing, and was able to do all the installs myself thanks to your DIYs. Thorough and clear explanations, good camera work, just perfect. I will bank up the PCV relo and catch can parts until I have cause for pulling the SC. Again, much appreciated!
No problem man! Happy to help!
Has the final kit been updated/verified on the Q7's 3.0T (Engine Code CJWB 2)? Mine is an '11...
Check out the Facebook group linked in the description
Thanks! Great vid. Question. Why did you replace the catch can? Any reason to not use the original metal one on the new valley setup?
That one is still being used
Would this work on Q7 3.0t 4lb?
When will this kit drop? I need the future to hurry up hahah
Hi guys, did you make a kit for it yet?
There is a kit from mercracing for all the pieces you need to make this a bolt on job, but you still have to source other parts outside of that kit to complete this.
Okay that’s awesome 😃👌
anyone did it on the CREC ? i'm planning on doing it soon ! lmk if anyone has had success or hiccups !
Yes they have but they have to modify the plastic oil separator that attaches to the metal valley pan to fit. There is a post in the Facebook group about it
Awesome vid bro 👍
Thank you!
Would this be of any benefit to a 13 q7 with the supercharged 3.0?
Absolutely. Same engine
Awesome video and Innovations dude! I just did my PCV recently and I hope I don’t have to do it again soon but if I do, I know how ima set it up!
Looking forward to seeing some of the more refined parts start shipping!
How are your valve stem seals doing?
Does this work for crec engines?
Hello guys, can someone tell me are c7 2012 3.0 TDI Quattro paired with 7 speed automatic transmission reliable and are there some things that I should look for when buying? Thank you
They are very reliable. Just make sure basic engine maintenance was kept up on (oil changes) & transmission services are completed.
Very good cars. Have the same one for a year. So far only issue I had was overheating. Found out a coolant hose was cracked underneath supercharger. Replaced and no issues. Expensive to maintain
Has anyone had luck ordering this kit lately, I ordered in December but have not received any confirmation. Getting no replies to emails either. Just waiting with my car in pieces right now.
The order in December was a pre-order. We were very clear about that. Mercracing is waiting for parts to arrive from factories.
@AudiC7Owners Sorry, didn't see on the merc site when I ordered. Just saw that orders would be processed in January. Still excited to get my car up and going again, thanks for the info.
This is such a good informative video, I’m UK based and need to do my PCV asap. Not too confident doing this myself as I’ve only owned the car 2 weeks but I think even if I wanted to do this I’d struggle as I won’t be able to get the parts from these companies here in the UK. It would be good to know if there are any UK suppliers that have approached you though
Mercracing will ship overseas I believe
@@AudiC7Owners ah that’s good to know. Doesn’t seem like there are many specific shops/garages that specialise with these 3.0tfsi engines here in the UK that I’ve found. Think I’d struggle asking a specialist to do this relocation, unless I try do it myself :/
Is the spider hose not supposed to be screwed into the metal valley pan? It has what looks like a hole for it to be screwed down. Is it just kept pressed in by the supercharger?
In videos on replacing the air oil separator in the 3.2 A6 it normally comes in, there is a long screw/bolt but I can’t find a part number for it.
It is, and I uploaded a short about it. The oem bolt costs nearly 40$ so I just found a random one in my part bolts bucket that worked
@@AudiC7Owners well shit. I didn’t see the short and just finished getting everything put back together. Time to take it all apart again.
@@AudiC7Owners I went through every one of your shorts and can’t find the short about it. Do you know what kind of bolt you put in or what the part number for the OEM bolt is? Would one of the bolts used to screw the new metal valley pan down work? I’m leaving for vacation today and will only have two days after I get back before I have to drive 1000 miles to university so I’m hoping to have the bolt ready to go for a quick install when I get back.
I believe this is the part number

Will this work on a 2016 Audi a6 c7.5 crec ?
We think so, but no one has tried it yet so we dont know for sure
Great stuff, very impressive. I’ll have to wait for the plug and play version, don’t trust my cutting and JB welding skills🙈😂. This will probably be one reason for keeping my B8.5 S4 a bit longer 😊
Haha I understand. But the piece you have to modify is only about 15-20$. You free buy two so you have one to choice on. Then you would already have an extra diaphragm to have in case yours ever tears. Win Win! 😂
@@AudiC7Owners oh I forgot to add…..I’m on the southern tip of Africa, South Africa to be precise. By the time we get parts here, the 20/30$ becomes closer to 50/60, due to our week currency and ridiculous shipping cost. I’ll be following this post/vid very closely
I’m throwing a PCV code on my 3.0 c7.5 Has if been tested for us yet? If so I’m ready
This kit does NOT work on a C7.5. We have dual port injection (as opposed to direct injection) and a very different PCV. You can use this video to help you DIY replace your PCV, as well as the one by FCPEuro, but don't buy these parts expecting to put a catch can on your C7.5 (or C8.5).
It actually does work, but you have to modify the plastic oil separator that attaches to the metal valley pan to fit correctly. We have had multiple CREC vehicles do the relocation.
Yeah this is awesome but the carving out and glue are non starters for me
There might be something to telegram that in the future but we aren't 100% yet.
Its not hard to do though
I didn't read through all the comments, so please be patient. Did you ever find someone who did the relocation on a later model engine. I have a 2018 A6, 3.0T. I was wondering if it would work.
This won't work on any turbocharged 3.0t
If you have the crec engine it will work, but takes some work to get the oil separator to fit.
@AudiC7Owners , thanks. I guess I'll have to look around the internet to see if someone has done it and what it takes to make it work. Do you happen to know a link to someone who has done the CREC pcv relocation?
@@nickrojas7185 Join our FB Group about the PCV relocation. I have a post pinned to the featured posts about it in there. Link should be in the description.
Very nice! Thank you for this.
I would buy a bolt on 👍 KR from Germany ☺️
Could you please elaborate a bit more, from where in Germany you buy it bolt on?
Absolutely amazing ! Can be fixed on C7 3.0 tdi 2011 CLAB engine ? And oil catch can ...
Honestly I am not entirely sure. I haven't done any work on one so I don't know what the pcv system on that engine looks like
@@AudiC7Owners The bad news for these engines is that the pcv system is built into the valve cover! This necessitated replacing those two V 6 covers and they cost around £500-600 in England only the parts! This 3.0 TDI engine is one of Audi's strongest!
Oh man that is interesting. I'm going to try to find a diagram of the 3.0tdi pcv system
Any oil smell sitting in car at a light with ac/air on?
None at all
Great improve is done!
i like the content real good stuff my mate
Thanks man!
Hello, could this kit work on 2018 q7 with 3.0T supercharger?
If it's the same engine as mine then yes. If it is a CREC engine then we aren't sure yet
I am just waiting for someone to test this also because I want to do this on my crec
Haven't had any CREC engines attempt it
Solid video Cam! Well done! Very thorough and complete!
Thanks man! & thank you again for letting me borrow your adapter to use in the video. I'll get it in the mail this week 🙌🏻
been dying for this video to drop! keeping fingers crossed for a full kit that includes AN lines!
what about using teflon tape around the end of the AN fitting that's going inside the larger of the holes on the PCV for a tighter fit? or do you think it will get too hot?
It's unnecessary with the AN fittings
i want to buy this kit so badly but i dont know anyone to help me with this. I am too scared of breaking or fucking things up and my car has been sitting.:(
Where are you located?
@@AudiC7Owners Midwest in wisconsin. We don’t have very many Audi mechanics at least right where I’m located and it’s been incredibly stressful the last 2 weeks w/o a car.
There are a ton of video references to be able to do it yourself. Try to find a local audi club near you
@@AudiC7Owners haha I’ve watched most of the series. My issue is having tools and the knowledge of this specific car as a whole. Not sure if it’s able to be ran in it’s current state if it’s going to end up damaging it vastly more or not. Will definitely look into some clubs or something around me. I appreciate it 🥺♥️
I'm gathering parts for this...did I miss a parts list?
Did you read the description of the video?
I did, found it about 30 seconds after I posted...finding a used 3.2 oil sep plate is proving to be fun!!! Awesome write up!!
Good luck!
How much pressure is under the supercharger for the plug underneath? Could you use a rubber freeze plug (the type that tightens with an internal bolt)? How about a hard metal freeze plug inserted? Seems like any of these DIY options would eliminate the need for a special part only available at one or two places. Thoughts?
Just buy the mercracing plug. It's extremely affordable for piece of mind. I will never recommend a plumbing plug for something like this. If you choose to go that route, do so at your own risk
Did this kit come out?
Been out for a year
Any updates on the bolt on kit? Are you near ct?
With the full parts kit from mercracing it is a bolt on procedure, but you still have to buy parts outside of the mercracing kit.
And no I'm not
@@AudiC7Owners your awesome
can this be done in a Q7 with the 3.0T
I think so, but no one has tried it yet
