Hi All,
Having a few issues with my GTI DSG cutting fuel/ loss of power at the moment

started getting these problems ever since i bought the car... when cruising on the motorway it decides sometimes to drop to 4th gear and cut all fuel and has a loss of power and will return back to normal however sometimes it needs to be turned on and off to return back to normal. I have changed the done the below and still has not change:
1 - Low Pressure Fuel Pump
2 - High Pressure Fuel Pump
3 - Cam Follower
4 - Had a Stage 1 Map took the car back to normal and still the same
5 - Spark Plugs
6 - Fuel Filter
7 - DV
8 - Fuel Pressure Sensor
9 - Fuel Pressure Valve
and the car still does the same and i have ran out of options??
