So as I'm typing this my wife's 1.4 HDI is being looked at for an annoying vibration / rattle.
The car doesn't need to be moving for this , just holding the rev's at 1500 does the trick .
I'll reply later with hopefully the answer
All sorted ... It was a bolt missing from the bracket that holds the Air conditioning pump to the car ... Not sure if was ever put in , or it has come loose with driving.
It had nothing to do with the Air con recall by the way
