Hi there folks,

I bought my first bmw - a 535d back in april. So far so good, I'm enjoying the car etc.
Over the past 3/4 weeks it's developed a sort of groan and judder when turning right slowly - eg going around small roundabouts. It feels as if something is rubbing and the power steering sounds like it really struggling.
The car has a fbmw service history and the last mot had an advisory for new drop links. So I had my trusted local garage change them and check for any problems that could be causing this.
Needless to say, he couldn't find anything wrong.

He did mention that my front right shock had some leakage but reckons it was nothing to worry about.

So I tried the car with the new drop links and the next day the juddering was the same. Seems worse first thing when the far is cold.
I went to the garage on my way home from work and he came out for a spin - typically I couldn't make it happen when he was in the car with me no matter how hard I tried!!

Please can you offer some diagnostic advice on what could be causing this.

All the best
Nick
