Just finished the following work on my 2007 E90 335I N54 103k miles

1-VCG
2-Valve cover
3-Thermostat hose replacement
4-Radiator hose replacement
5-OFHG
6-New Oil filter housing
7-Walnut blast
8-Serpentine belt
9-Rob Beck PCV valve
10-New vacuum hoses where needed

Car is running like new, however I am getting a P0444 Code (Evaporative Emission System Purge Control Valve Circuit Open) from the general OBD reader. No specific code on the BMW specific code reader.

Of note: Already had water pump, thermostat, Alternator, plugs, coils, index 12 injectors, vanos solenoids replaced.

Can anyone help with this? I took out the RB PCV valve and checked it and placed it back in. Code went away for a minute and then came back after 5 minutes of driving today.

TIA.
