Is this the Camber or Toe adjuster

Hello, I have been trying to solve a camber issue I have and have been told that the camber adjuster bolt is the one that connects to the subframe just behind the back box. I managed to get this moving last night after some gentle persuasion however it didn't seem to turn very far, maybe quarter turn.

I am now worried that this may not be the camber bolt at all after seeing some pics on a vw forum that call this the toe adjustment bolt. My question is am I trying to adjust the correct nut or is the camber bolt located elsewhere.

Cheers for the advice. I had taken it to a laser alignment specialist and it was them that told me that the bolt on the left of the pic was the camber. They were doing their best to adjust what they though was the camber bolt but had told me it was seised and I would have to get it moving before they could help me.

What a waste of time, I spent all that time freeing up the toe adjuster and had nothing wrong with the toe.

Cheers for the advice will be getting it sorted this week one way or another
