M52b25 Single Vanos 98

State of the car is as follows

Replaced a whole bunch of stuff ofcourse,

All Sensors were replaced, clutch was replaced, cooling system was replaced including thermostat and it's housing, Transmission control unit, airmass and suspension complete replacement.

The issue was not apparent at first much as the car was mostly running with the clutch open at all time - i am assuming this is the reason - once clutch was replaced and engine started running at 92-100 loss of torque is very apparent

Car starts very normally in the morning cold or hot
Power is fine but not normal ofcourse but still better than before the engine warms up and gets to 85-95-100

Exceeds a 100 once every 700 kms or so for seconds and goes back to 98-97

I have carly obd reader and can take images of whatever you want to look at

When d/c airmass still runs the same as if nothing happens just bogging down in idle

Please let me know how to trouble shoot or fix this issue.
