I had that problem with my 2015 GTI I replaced the O-ring, latest cap, eventually I could see the leaking happening again so I let it be.

So i replaced the cap with the new yellow one. That didn't help. Still got leakage and quite a bit. So just put on the O ring. Seems tighter, so hopefully that'll do it.

The problem isn't the o ring but the main seal.

I changed mine out today with the red seal and green o ring. The original cap has a black seal and no o ring. No leakage previously (maybe slightly?) but precautionary change to prevent future possible leaks.

Got the kit for ea888 gen3 from AliExpress:

I have purchased the Aliexpress gasket kit as well. It has stopped my leak for now, will update as the miles go on but after about 400 miles it still looks good. I also have the newest revision cap.

Great find! How does rubber handle?
Did an oil change and no leaks so far!

Actually I have an update on this. I purchased another product off of AliExpress that extends the filler neck and makes filling the oil easier. Link: https://www.aliexpress.com/item/3256803333069258.html?spm=a2g0o.order_list.0.0.21ef18028cpWDZ




Just got done install this right now. This extender screws on where the cap normally screws on. It uses the older style rubber gasket that was replaced by the orange gasket (of the orange gasket and green o-ring kit referenced here: https://golfmk7.com/forums/index.php?threads/oil-around-filler-cap.347218/post-7859834). I took the orange gasket and the green o-ring off of the original cap and replaced the black gasket on the neck as well as adding the green o-ring to the extender neck and then screwed the neck with the orange gasket and green o-ring upgrades onto the original port and put the new oil cap on the extender.

I'll once again report back after a few hundred miles to let you guys know how the new setup is holding up. Since the orange gasket is doing fine so far, I see no reason why it would leak on the new setup. Hopefully oil changes will be easier in the future not having to mess with the stupid opening to the oil cap where funnels and other things don't fit easily and it being in a awkward position to pour in oil directly.

UPDATE: Green o-ring also works on the extender neck. I've added it into the text above.
