- In this video I will finally be putting my RS6 back together following a long DIY process of replacing the Turbo Oil Strainer, Check Valve and PCV unit. In the last video I almost made it before finding a fatal coolant leak requiring yet again another new part, the thermostat housing!
Part numbers used in this video:
Water pump Thermostat housing: 079121115BL
Thanks for watching
Congrats, thank you for the series, very useful for us!
Thank you so much for the kind words and support, so pleased you have enjoyed the content :D
Thoroughly enjoyed the series mate, great detail and very well edited. Also didn't realise I 'needed' under stairs storage till I watched your back catalogue...
Looking forward to seeing what's next for the channel, keep up the good work!
Hey thanks for watching and so glad you enjoyed it. Haha good luck with your under-stairs storage build. Top Tip.... don't build it outside without checking you can get it back inside lol!!!
Good call with the original pipe by cleaning it up etc - in my view. Thanks again for a great video and a super honest and informative video series. I've watched the lot! Top Tip - when you go to do your brake discs, fit armoured hoses all round and blue back pads. You'll not be sorry!
Good shout, I will add them to my future upgrade wish list. Still deciding on a colour for the callipers.
Than you very much for sharing this with us.

Amazing content mate, Cheers for the series
No problem, pleased you enjoyed it. Stay tuned for lots more random DIY madness!!!
Well done mate, great video with excellent content, keep it up
Hey, thanks so much for the feedback and support :0D
Excellent Job! another great video too.
Nice vid! Myself have an c7 S6. Same engine. Nice to see the diy.
Thanks for watching, hope this helps with any future DIY maintance for yours :)
Good video, keep the content coming 👌
Awesome thanks Buddy :D
I have to carry out the same operation on my rs6 Congratulations. Your work is very inspiring. Can you give me the news regarding the suction at the oil cap?
Hey thanks for watching. Yes I can confirm suction before and after was exactly the same. In the end I think my PCV unit was still good but worth changing anyway as it had already done 48k miles and would need replacing as somepoint 👍
Great work pal
Thanks Buddy :)
hello, what were the symptoms of the problem, because I also suspect the same problem with my Rs6
did u test if the vaccume changed on the oil cap?
Kindly let me know I am about to have a dealer do the recall on the oil strainer and want to know if i should replace anything while he is there to save on labor
Hi, after changing my PCV unit I can confirm that the vacuum stayed the same as in the clip shown. I don’t think my PCV unit was actually failing to start with so no difference. I would strongly recommend getting a new one fitted whilst they are doing the strainer though as replacing it in the near future will be almost the same abit of work and very costly in labour. PCV unit it’s self it only around £150.
@@InDadsGarage first great video! Second so if the PCV wasn't the issue what was causing fuel in the oil?? I am having the same issue and trying to diagnose
@@2smart3guys hey, I can confirm the vacuum didn’t change after I replaced the unit. But I think my PCV unit was still ok in the end. However I would recommend asking the dealership to replace the PCV unit whilst doing the oil strainer, especially if you are over 40k miles. It’s only a £200 clip on part but would cost you a great deal more in labour if you need to replace it as it’s a while front end strip down as you will have seen.
How many hours labour to do this mate?
Hey man thanks for watching. As a novice mechanic but now having one under my belt, I’d say if I was to do it again with all the parts to hand and no issues then, 1 day to strip it, 1 day to fit all the new parts and put the majority back together, then a half a day to bleed the system, refill coolant, oil change refit bumper etc. is never that straightforward though and something always goes wrong. One stuck bolt and it all goes tits up lol
Have you upgraded your interior lights as mine are just plane white and are just a bit boring ..
Yep, LED upgrade, I'll do a video on this once I hit 1K subs ;0)
What year is your RS?
2016
@@InDadsGarage It looks really clean for the year, keep up the good work.
What do these do MPG wise? Is it a Euro 6 Version?
They are a Euro 6, if engine is in healthy condition you should get around 17-23mpg or so in mixed driving scenarios. If constantly in and around town or doing a lot of short journeys expect a bit less, (especially if you have a heavy right foot). On longer journeys they are surprisingly good on fuel, I've had 30mpg out of mine. I usually get around 20-24mpg, my use is mainly A/B roads with the odd enthusiastic overtake (ahem), and on motorways can easily see over 28.
@@sarcastixx74 thanks for the reply
Depending how you drive it...
Drive it like you are taking your Grandma to the shops the maybe 24-26mpg
Drive it like you stole it sub 15 mpg.
I went for a spirited drive the other week and got 60 miles to £30 of UK premium fuel.
Its all about the enthusiastic overtake, quick V8 rumble and then straight back down to economical speed lol.
