Hey guys! I had a question about the DSG fluid replacement procedure technique, perhaps someone who has performed it can comment.
I see the procedure is to basically:
My question is: why not just keep the drain port fill plug in the transmission with the ball valve closed after filling? (like this one: DAP # VAS6262 ) Once the transmission reaches the prescribed temperature you could open the ball valve and let the fluid drain. Once the fluid slows to a drip you could then swap it with the OEM drain plug and torque it down.
The only logical issues I can imagine with this are if the pressure in the transmission is high enough to possibly blow off the tubing from the fill plug but this seems unlikely since the DSG has an overflow vent. The second issue I could imagine is if there is a small window of opportunity between 35C and 45C temperatures where the fluid might not drain fast enough out through the drain port fill plug.
Don't take this too seriously, I'm just surprised the procedure is "try to be quick and not spill much" so of course I imagine myself bobbling the drain plug as all the fluid pours out
Thanks!
I see the procedure is to basically:
- overfill the transmission from the drain port,
- quickly swap the drain port fill plug with the OEM drain plug, and try not to spill too much fluid in the process.
- Next you warm up the transmission fluid to the prescribed temperature (35C-45C) and then remove the OEM drain plug to let the excess fluid escape.
