diff oil drain plug location - 2017 T6 4motion

[jeft6]

I want to change the oil in my rear differential (not in the haldex), but, somehow, I can't seem to find the drain plug.
I was expecting it to be the middle of the three bolts bottom right in the picture, but that's not a bolt. Can't find any other option. Help!

And, the hole on the bottom of the diff (bottom right in the picture) is just a hole, not e.g. an inbus bolt. Unless I'm missing something.

I don't believe there is one . My 2018 van doesn't.

Oh right, that would explain things. This means there is no need to change the diff oil? Only haldex clutch oil?

Extract it with a vacuum pump.

Yes, that would be possible indeed, I have found the fill plug. Would you think that's necessary? Car has 140000km.

Have a Search on the Forum, I’m fairly sure somebody drilled and tapped a drain port not so long back.

That would probably be me.

I would. Its so inexpensive it'd be daft not to.

@jeft6
Here’s your solution.
You could use a vacuum pump but you’d never get all the debris out.

Indeed, thanks a lot everyone!
