I'm also intrigued by that part. On my 88 and 91 S4 the only hardware attached to the pump is that little metal wire support for the supply line, also shown here.

I've never seen that stay in the photo or heard it mentioned in years of following Rennlist!

Roger, Adrian: sorry for having created this "excitement", I should have posted a more clearer picture and/or explained upfront.
This is nothing more (nor less) than a very large 13mm (IIRC) wrench, that was only temporarily attached to the PS pump side (for easier removal of one of the banjo bolts "in situ"). The angle of my posted picture makes it look like a support stay, but it is not.

That explains it, thanks.

It's a very thin wrench!

129 euros and well worth it.

I used this stuff https://www.ryco.com.au/resources/hy...dex.html#p=146 on my power steer hoses when I had them rebuilt. When I did the fuel delivery line on the other side, I also encased that , so that any leaks would fall out the bottom rather than spray the exhaust.
