Hey guys, where do you fill oil for s-tronic on 13 Rs5? Iíve done something stupid and need to fill about a quart of it back in. I already feel pretty stupid about it, so Iíll spare you the details.

Iíve looked around and donít see a filler plug anywhere from the top... is it done through the drain plug like some of the older models?

Also, what type of oil do I need and is there a local place to get it or is it dealer only item?

Thank you!

It's on the side of the transmission. There's two, one for the ATF side and one for the gear oil side. Don't mix them up. I don't have my service manual PDF's with me at work otherwise I'd post some images for you.

You're in luck, forgot I had my laptop with me.

Thank you so much for the picture. Which ATF fluid goes in these cars? Can I buy it at an autozone or somewhere local? Dealer is closed until Monday.

I honestly haven't researched the right ATF but I'd imagine it's Audi-specific, dealer supplied. You could probably search here in the Forum or on one of the vendor sites like ECS Tuning that carry those supplies. Find out which non-Audi brands work and see if anyone carries it locally.

Another angle of the plug
When ATF temperature of 30 įC (86 įF) is reached, unscrew
ATF inspection plug -arrow-.
ē ATF level is correct when at an ATF temperature between 30
įC and 50 įC (86 įF and 122 įF) a small amount of fluid drips
out of the inspection hole . If this is not the case, add ATF.

Filling...Must be between 86 and 122 degrees (fluid).
Ė Remove the ATF check plug -arrow-.
Ė Engage the filler hook from the ATF Filler Tool - VAG1924-
into the ATF inspection opening.
Ė Add ATF using ATF Filler Tool - VAG1924- until ATF drips from
the check hole.
Ė Move the selector lever into ďPĒ.
Ė Start the engine, wait 20 seconds and then turn it off.
Ė Add ATF using ATF Filler Tool - VAG1924- until ATF drips from
the check hole.
Ė Start the engine and let it run in idle.
Ė Continue to add ATF using ATF Filler Tool - VAG1924- until
ATF drips from the check hole.
Ė Install the ATF inspection plug.
Ė Check the ATF level. Refer to
⇒ ď7.2 ATF Level, CheckingĒ, page 134 .

Looks like Liqui-molly 8100 dual clutch synthetic oil ATF fluid works. ECS Tuning sells it for the RS5 so look to see if you can find that locally.

Ravenol makes a DCT/DSG fluid which is also works. Must meet Audi/VW G 052 529 A2 specifications.

Thanks a lot man, I really apreciate it. Yeah i found the fill plug... itís right to the side of the atf drain. I guess, the other one is actually a sensor on the rs5 as there is no other drain plug that I could see... but did find the sensor which is in the location from the picture above.

Iíll go do some checking on the ATF fluid. If nobody has it, then Iíll just have to order it.

At least the oil change was easy... once I removed the aluminum cover plate.

Thanks again!

Just for reference for others, here's a shot of the sensor that can serve as a fill depending on manufacturer date but it's for the manual transmission fluid, not the ATF side.

So, then, that first picture doesnít really apply to rs5, right? When I looked under mine I didnít see 2 drain plugs. I saw one atf drain plug, one atf fill plug on the side, and that temp sensor plug... thatís it. Actually, I didnít go that far back to see if number 3 plug is there.

To get the factory service manuals for the RS5 go here:
https://erwin.audi.com/erwin/showOrderFlatrate.do

You'll want the 24-hour flat rate which is under $40 (euros, so it fluctuates).
You'll sign up for an account (free). Choose the flat rate one day. You'll then be able to search for any and all PDF's related to the RS5 and A5 line. Some of the PDF's don't specifically say RS5 and will say A5 repair for whatever but include RS5 information. So I downloaded pretty much everything I could for the A5/S5 and RS5 and sorted through it later. Just search a number of different ways. Plus you can download lots of other cool docs on other models.

Once you've downloaded, you can open them on your computer at any time. If using Adobe Acrobat, disable Java and you'll get rid of the initial warning PDF that pops up. You just scroll to the bottom of those and hit "Ok" and the FSM opens. But just disable Java in the preferences and you don't need to do that each and every time.

Yeah see if the third plug is there...here's the MTF drain.

That's the RS5 OB5 transmission in that photo. It depends apparently, on the build date. They vary on the MTF drain/fill side by build date. Strangely German, LOL.

I haven't looked at mine that close yet but I'll be doing the 55K service, when time, myself. I may do it early just for peace of mind. I'll change ATF and MTF just because.

Also, to make oil changes easier, get one of these:
https://www.ecstuning.com/b-schwaben-parts/6-liter-fluid-extractor-filler-system/007221sch01a/

And then this:
https://www.ecstuning.com/b-schwaben-parts/schwaben-dipstick-oil-change-tube-set/013810sch01a/

Just received this combo and it'll allow you to change the oil from the top side and you won't have to jack the car up.

I was surprised just how small it is. Not hard to store somewhere when not in use. For some reason I was expecting it to be much larger.

Yeah I donít have that drain plug... just the temp sensor instead of it. Iíll look tomorrow for the MTF fill plug. Leave it to Germans to make things difficult.

I drained 10qtís of oil when I did the oil change... so that 6 liter pump may not be enough. Youíll have to drain it in the middle. Amazon sells one thatís 10 liters... that may be more doable.

I agree, though... this is the last time Iím changing it the old fashion way. Removing that metal cover is a pain in the ass. They could have left a little cutout for oil change, but nope.

Yep, you have to stop in the middle and pump out of the extractor. There are larger ones out there but I've not seen any consistent reviews on them like the Schwaben. Just read the reviews and make sure it has the right size siphon tube as well. Some have a manual pump (like the Schwaben) and some require an air compressor and have no hand pump. Some have both. Some only extract and don't pump out meaning you have to pour it out into another container for disposal. Also make sure there's a check valve so it shuts off when it gets full.

They also have a pump for the S-tronic for getting the ATF/MTF fluid back in more easily. I have a Motive vacuum bleeder that'll probably do the same thing but I don't want any chance of fluid cross contamination (even though I clean mine after each use). https://www.ecstuning.com/b-schwaben-parts/3-liter-multi-functional-filler-system/007311sch01a/
