I would say the thing to do would be to take it to the workshop and let them have a look at it - but not to change anything. If they think they could improve it, let them have a go - but make sure they can get it back to how it is now in case its worse!
could you perhaps give me a hint, what they should change/check or look for or is it obvious for mechanics being experienced in that?
