Cold start - golf R (CDL) fuel pressure issues

When opening driver door, the lpfp primes the fuel system to around 5.5 bar. Im still trying to find out if the dropping to 4 bar during cold start is acceptable or not good. You can also see the rail pressure ossilating while the engine isnt running yet while the low pressure fuel is stable. Maybe because the fuel rail pressure has a much bigger range?
Anyway still getting P310B - fuel outside specification errors and thus fuel cuts while accelerating with WOT.
