[E60] 452A 452A Info - Partikelfiltersystem - advice needed

Hi guys,

Was playing with INPA reading errors and found error 452A 452A Info - Partikelfiltersystem
full info as follow:

any idea how to fix it? tried to reset it but it comes back
also, there is a weird PWG reading as on the attached screen - have no idea what is this

thanks in advance
