Hi there - i'm from Austria and owning a D4 SDV6 BY2012, which I bought in Mai second hand.
I'm very happy with the car - except:
poor accelleration from stand - specially when cold
it takes some seconds until the engine begins to rev. up - no matter how mutch throttle
performance lack around 2.500 rpm (below and above is perfect)
accellerates up to around 2.500 fine, then it seems to "hang" around this value and
then proceedes to rev up again.
is this the point where the turbos switch over - is there a context ?
Are these known issues - is there any suggestion, how to get rid of it ??
Thanks for the help
greetings from Tyrol

There can be a lag before things happen from stationary. Something you can learn to live with, they do all seem to do that, but if it's very noticeable or annoying to you, then do a search on here for more information. Not so much with roll on acceleration. You can tell when the second turbo take effect, but things should be pretty smooth really.

EGR may cause issues from cold and power...... someone with more knowledge will confirm/deny!!!

Have you had the throttle sensor checked, there was a TSB on hesitation accelerating at low speed
Replacement brake sensor & a gearbox reset cured the issue on my old MY12Paul.
