Its not consistent the best rattle seems to come at 15c water temp, thats usually about 2-5 higehr than ambient, figures taken off scan gauge, the rattle will still happen up to 20c water temp.

Did it badly this morning. First time the car has been driven on a cold morning for ages so that would explain why we haven't had it happen much since the EGR was replaced in February. I am interested to see if we get the same response about needing a software update from LR as DB/MM.
Can you tell me more about this rattle? You see, mine will rattle for perhaps 1-2 seconds after firing when I start it in extreme cold , then run normally. I then give it a few minutes at idle, and drive off gently until it reaches operating temp. I thought all diesel engines will do this type of rattle thing.
Is this what yours is doing?
I;m guessing from solmanics other posts in the past its similar to what ours does not on start up but when being driven
