- This is the second and final installation for carbon cleaning your B8/8.5 Audi RS5 with the 4.2L CFSA engine. Many aspects of this DIY can be applied to other Audis. There is more technical detail and a full list of supplies at tinyurl.com/rs.... Be sure to like and subscribe!
Hello,
Thanks for all your great videos, they are really inspiring, I am looking for an RS4 B8 and intending to maintain it myself, your videos will be of a great help.
Thanks for taking the time and sharing your work and congratulations for your beautiful car !
Best regards
Konstantin
Thanks Konstantin and glad I could help! Be sure to check out my website, www.redmistracing.com, if you need any high performance parts.
Hi there, first of all I wanna thank you for the comprehensive videos you’re posting. I’m gonna “attempt” a carbon clean myself based on your instructions. I’m hoping it’ll also be successful 🥴.
I gather I think everything I need, ( been ordering parts for a month now ).
I’m also planning a coolant flush accessory belt, spark plugs, air filters and general cleanup of the layers I get to. Also after done with this a pan drop transmission fluid ( ordered Ravenot ) and differentials.
I’m a bit scared but hey ! if it’s not scary we shouldn’t do it right !.
I also think I found a solution for the pesky grommets but I’ll have to get back with that if I reach the conclusion it actually works.
Thanks again ! And…….wish me luck 🫶
You are most welcome Rares and good luck!
@@RS5Fanatic So far it’s was fun, the solution for the grommets worked really well, don’t know how you do the process so fast as I spent a whole day on 6 cylinders just to get them clean. So far brake cleaner used in moderation was the fastest to dissolve the gunk. I also must be the only one on the planet that had the injector on cylinder 1 stuck that when I used the pulling tool the whole plastic end snapped so now I had to pull it out. Took a block of plywood, a crowbar a vice grip and penetrating oil to get it out 😡. Called the dealership for replacement air ai ai, on back order and also expensive a/f so I’m waiting for eBay to deliver a couple of used ones purchased for 150 🤞. I need to clear my friends garage so I went and took it out of service position assembled the bits in the front, did spark plugs after gapping them and so on.
I can’t do much else without the missing injector.
Also I meant to ask how nervous should I be about the injectors acting up, I didn’t protect them from debris as much as I should have. Is there a way to clean them somehow ? I heard at home is pointless without ultrasonic machine pressure testing and so on…..
Thank you !
@@RaresBalanean It took me a day to do it initially. If I had a larger air compressor at the time, it would have gone more quickly. Debris shouldn't hurt the injectors but a bit of tape over the top can't hurt if you've left them in the bores. It's important to make sure you replace the teflon seals if the injectors came up out of the bores at all. And to clean the bores really well. The latest injectors have "AD" at the end of their part number. They seem to be more reliable than "AC". You are correct on cleaning at home, can carefully wipe off the injector end but that's about it. I don't think ultrasonic cleaning works either as you can't test them at actual operating pressure and the internal pintel wears/develops cavities due to carbon so you then get inconsistent flow. New injectors are your best bet but $$$$.
@@RS5Fanatic Alright, so rigged a 12v transformer to energize the injectors, then simulated the fuel rail cup so the o-ring seals and through a hole in the cup blasted carburetor cleaner through for a few times and they atomized alright given the can pressure. Also I wanted to check if they leak, all that was for my peace of mind mostly, then assembled everything back according to your specs.
Started at second try, ran rough for 5 seconds then settled down lovely. I had my VAG connected I have OBD11, had 4 faults but I assume they were from removing the battery.
Cleared faults and rescan, no faults after that. So I’m assuming I’m in the clear.
I did a coolant drain, only about 2 gallons came out of almost 4 🤷🏻♂️, I guess a flush would have been better but the coolant looked alright so I’m not too worried.
Runs fantastic, I think consumption improved, is more responsive, shifts better, and sounds better.
Thanks again for your support.
@@RS5Fanatic I was also mentioning the grommets I don’t seem to have a way to attach short movie here to show you what I did to basically eliminate the spacers drop issue but basically ordered some 9lbs 3/4” neodymium magnets with countersink holes in them and put a longer countersink head bolt through the magnet creating a handle, came handy in pulling the loose bolts out and then just dropping it on the grommet/washer, lucked out on the diameter but they ended up roughly the size of the grommets.
"Hi fabulous, I have an RS4 B8, I believe it's the same. I would like to start this cleaning process. Where can I get the manual + your video? It would give me more confidence."
Awesome videos. Best that I’ve seen on UA-cam… Thanks!
Thanks Andre, the means a lot!
Epic!❤
Hey mate,
Do you know if the injectors need to be re learnt if your replacing a new unit?
I know with the TDI injectors you code them in but I can’t see anywhere in the workshop manual for such a procedure for the FSI units
No
