Mine had the EGR replacement on the last service. My post is a few down from this one.

However since its been done the engine maintanance warning notification comes on in the sencus display panel, which im sure is related to another EGR problem. The car is booked in for some other work (upgrades i have ordered) so i will get them to check the EGR then and will post the outcome on these forums.
Car was fine for a few weeks after the EGR replacemnt and tbh I cant tell there is a problem other than the warnining notification im now gettting. No limp mode has showed up.
