[HOW-TO] PDK Fluid change

Looks like Pentosin has a kit for PDK clutch fluid, just doesn't include the gearbox/diff fluid (mobilube?). I know the OEM fluid is Pentosin FFL-3 for clutch.
I am still kinda confused as to what goes where... I would want to do the Transmission + Clutch + Diff (if needed)

Kit contains: (Qty.) (1) Transmission oil pan with filter and gasket,(6) liters Pentosin FFL 3 trans fluid, (13) pan bolts, (1) drain plug.

That kit is for the clutch fluid. FFL3 is for the clutch.
mobilube is for the gearbox.
The picture at the top of this thread with the “pdk gear oil” is wrong. Don’t put oil in there.

Thanks.

I started doing this to get ready for track season. Ended up removing the "PDK Gear fill" screw before realizing it is NOT the gear fill screw. It was a weird looking screw with something that looked like thread locker on the end.
Is this going to cause an issue? Have any of you removed this screw by mistake?

it’s subjectively more quiet, I have learned to live with the clunk, I only hear it if the windows are closed

I've looked but can't find anything.

Finding this bolt was super hard. I bought one just to compare to the original because I was in panic mode at that point. It’s an aluminum vented shoulder screw with this special thread locker/sealant on it. There’s also a sealing washer under the head.
honestly I’m not sure how you snapped yours off now that I’m thinking about it. It’s a Allen key. Is the rest of the bolt stuck in the hole? You’ll need to be really careful with extraction. The screw bridges a gap between casings in the transmission. Parts of the screw, damaged thread material, tap cuttings (if you have to chase the threads) can and will fall into the PDK gearbox portion through the gap.
The first few dealers I called refused to sell it. I don’t remember where I ended up ordering it from, but it wasn’t cheap. might have been a shop in the UK?
I ended up reinstalling my original, so I still have the one I bought floating around some place. It’s brand new. I’ll sell it to you for $100 shipped.

It's a shame that we cannot correct the first picture showing the incorrect fill location in the first post on this thread. Obviously that's now at least two people removing the wrong "fill" bolt - probably based on that first bad picture.
Just to be clear for others reading this thread: the corrected picture showing the PDK fill plug is in Post 36 above by @Wacky.
@amet if you are able to edit your original post, could you replace your picture #1 with the picture in post 36? I hate to see others making the same (avoidable) mistake because they are putting their trust in that first image!

Thanks yes its fine I can remove it no problem and just slightly over tightening it caused just the top to shear off. It has a recess in the top for the little rubber washer.
I almost had mine out, i just screwed it back in and used some heavy epoxy plastic repair on it. Its not leaking or anything. When you say bridge the gap what does that mean, because it did not seem very long etc. I am in central florida by the way.

I drew you a picture. The job of that screw is to vent a space between the PDK transmission oil shaft seal and the PDK clutch fluid seal without contaminating the transmission oil. So its important that the vent hole remain open. The thread locker seals the transmission from the vent tube. The sealing washer under the head of the bolt seals the transmission from the outside. Hopefully the picture makes sense.
Honestly on a car this expensive, why are you happy with a bogded together repair? A new PDK is something like $25k. Replacing those seals are not "user serviceable". I think there is only one or two independent mechanics in the country that will drop a PDK for anything other than a replacement. Those seals are really hard to get to.
