Ok, did the search thing and can't find what I need. It might exist, but I am more familiar with cookbooks than motoring talk.

FIRST PROBLEM -
My car (details below sorry if I repeated anything or mentioned anything not required to be known) is shuddering when turning (left or right) at low speed/revs - ie parking, slow corners. It happens both on full lock and half lock. Cornering at speed - it does not happen (or maybe it just isn't noticable).

New tyres and rims fitted in July. No problem up until 2 weeks ago.

Thinking it might be as simple as power steering fluid top up. But would like feedback on other things to look for so I don't get fed bullshit if I take it somewhere.

Was serviced by MMS in July 2011 too.

SECOND PROBLEM -
STiNC needed to use my battery so disconnected it, now boost settings & change points have reset (to crapola), anyone SOR with laptop/software/know how to help. Beers on offer. Don't want to have to take them to be reset again - this happened when I had to get a new battery back in Feb 11.


Really appreciate any help that can be given.
