Hi lads,

So, next week im due to pick up an immaculate 2008 520d msport.
I forgot to check if it had the n47 engine in it. I presume it has though.
Car has full bmw service history but its well out of warranty.

How long is a piece of string question... Is this chain problem across the board on all n47's? How much, if i buy it to get it sorted before is snaps?
Should i simply just avoid?

Thanks in advance
Stephen
