I own a 2016 Octavia 2.0 TDI with the DQ250 6-speed DSG gearbox. It’s time to change the transmission oil, and I’ve come across two fluid part numbers: G 055 512 A2 and G 052 182 A2.

Which one should I go with for my car?

Also, is it safe to go with Liqui Moly Top Tec 1800 DSG? I’ve seen a few people recommend it, saying it performs better than OEM fluid — would love to hear thoughts on that.

Lastly, will 6 liters be enough for a complete service including filter replacement? Any tips, suggestions, or precautions from anyone who’s done this before would be really appreciated!

I think it's this one

G055512 is just gear oil for the DQ200

Plenty of info on here to check that though.
