I have 300E and my steering is relatevely light when cold but after car warms up it feels tight. I thought its normal but now I see other people have similar problem. I used to have same exact feel with my 420sel. Ive changed ps pump on 420sel and no improvement. Once I test drove another 420sel and steering felt very light. Is there a problem inside steering boxes and is there repair kit to fix it? Anyone have any info?
Thank you
