Golf MK6 2.0 Tdi CR140 rough idle + jerky accelation

[freddie2020]

Hi,

MK6 Golf 2.0 Tdi CR140 195k (with Diesel Gate map)

When engine is cold, and especially when outside temp is cold.
Jerky accelation for about 2 - 5 mins of driving till warmed up.

Had the intake manifold done for the P2015 fault.

Pointing towards injectors?
When all warned up issue goes away.

Thanks

Had similar on my Scirocco CR140 last winter. Mine had a fuel pressure regulation code and on checking fuel pressure actual vs demand it would be a 200bar difference , idle was very rough as you say and got better but was not perfect. Mine was fixed by the fuel pressure regulator on the end of the common rail, bought from Darkside Developments.
