Hi. I have TKN gearbox on my Karoq 1.5 tsi 2019, and I want to change the oil in the manual 6sp transmission.  the gearbox has two holes for draining / adding oil, I already have oil.  75w G052.  the plugs have an Allen key of 17. I read and looked that it fits 2.1 liters of oil, but people change it and it fits far less.  there is a trick to block the gearbox with a feeler near the gear selector and to drain more oil on one of the smaller holes.  Does anyone have experience to tell me if this is okay?

And  to unscrew the reverse sensor and pour oil through it, because it starts leaking through the filler cap already at 1.7 liters.

Look

I put 0.3 L more, now is 2.3 L inthere, hope not leak on driveshafts.

I drain 0.2 l do let it be like msnual says. 😂
