Last year my car had this as an advisory note:
Nearside Rear Lower Front suspension has slight play in a track control arm inner bush (2.5.B.2b)
I didn't own the car then, so I don't know what it means, so if someone could explain, and tell me if its likely to be a problem this year, and how much you would expect it to cost (ballpark!) That would be wonderfully helpful!
Thank you :~)

Hi friend,just means that in the examiners opinion,there is a problem but not enough to fail the mot at that time,he is indicating that in the future,it will have to be replaced,not a big job,shop around for the part.
Cost of part im not sure but should be no more than four hours labour.
He has done you a favour by flagging it up to you.

just means there was slight play in a rubber bush. could have worn more by now or might still be ok. usually bottom suspension arm is replaced as its easier and they are not to expensive. should be well under £100 at a small garage for the part and fitting plus vat etc if it does need replacing.
