Apologies for that - I was just hoping for some advice so that I didn't break down half way round and hold up everyone else. ie if someone had said it sounded terminal I would have pulled out.
Though as we now know, it was nothing that was going to break - and indeed hasn't since. Can't make it rattle on tarmac so haven't heard it since.
Oh and just for info (for those not in the same group) my 'whinge and whine' was "I've got a strange rattle so I'm stopping to have a look underneath to check"
Hardly a big offence - even though I did stop twice.
Personally, I would have thought the constant going on and on and on about it by everyone else would have been the most annoying part
BTW no offence taken
