Cold Start Kangarooing - 'Dump Valve Noise'

HI All,

New to forum, sorry to start with a problem!

I have a 2007 Mini Clubman Cooper S.

Only had it 3 weeks. First couple of weeks drove like a dream.

Last week I've had some mild kangarooing from starting, that lasts for about a minute. Also starting to hear a dump valve type noise when changing gear, which again has only started in the last week.

As I brought it privately I need to get it investigated - but any tips /ideas for now?

Many thanks
Lisa
