Haldex 3rd Gen Oil Change

Today, I had a 2006 Audi S3 8P in my shop, and I was going to change the Haldex oil and filter.
According to Audi, there should be a drain screw at the bottom and a fill screw on the side.
However, neither of those was present. The filter could have been replaced with a cover on the side, with the designation SW 24.
The filling volume should be 0.8 liters.
Can someone tell me how to make a change here?
It's not like the previous version, where the oil is pressed in.
Best regards,

Hello.

"Should it be the same as it is in my Golf 5 4Motion?"

I have a 5mm Allen screw at the bottom and one at the top left.

Best regards, Thomas from Vienna.

Unfortunately, there is no Allen screw there.

Hello.

Thinking is the same.

Best regards, Thomas.

It seems it is indeed the 4th generation.
I found a picture that matches the clutch for the S3.

The Haldex coupling oil will be completely replaced via the axle oil, starting with generation 4.
There is a filter that is installed on the Haldex system, and it is also very easy to replace using an Allen key.
