OK, the PAS pump didn't turn up as expected, so I decided to tackle that rust before it gets any worse. I just rubbed the worst of it down, treated it with some Kurust and blew it over with a rattle can. Was just going to leave it primer until I do a prettier job when the weather gets better, but luckily I found a barely used can of the correct paint in the boot.
Before:
After:
Not the prettiest up close, but not really noticeable from a distance, and much better than the two large rust patches, and should stop it getting worse for a while.
Anyway, between coats I had another look at the PAS fluid, turns out it was lower than I initially thought, so I topped it up and..........the noise has completely gone
It's obviously weeping from somewhere to get low in the first place, but it's certainly not ****ing out from anywhere, I'll investigate it properly when I do the wishbones. I'll just keep the PAS pump I ordered as a spare.
I also took a look at the boot as it won't open by either the remote release button, or the key. The lock seems to be damaged, and the solenoid itself is faulty as there is power getting to it when the button is pressed, however if I manually move the solenoid I can open the boot, so I have a solenoid on watch on the bay at the moment.
CBA has kicked in now, but tomorrow I'll be tackling the interior and giving the outside a good wash
