bit of a thread revival..
took the d40 in for it's first service which is just a general checkup, nearest dealer is a 45 min drive away, car drove perfectly all the way there as you'd expect.
picked it up afterwards and it was lacking power and not boosting properly, seemed to be a bit noiser and running rough too.
took it back, had 2 different mechanics look at it, put the diagnostic on it and nothing come up, a bit of tinkering and he thinks there's a problem with the turbo.
booked in next thursday for diagnostics, currently fighting for a loan car..
car has done just over 2000km.
might pay to unblock your egr if they are going to be crawling all over it just in case, They will use any ecuse to make you at fault.
