We have been facing issued with updated P&IDs actually reflecting plant build. Should there be some regular checks /audits to see existing practices?

Re: P&IDs Updation
You would not find this weitten anywhere that you need to have such a check or an audit process in place but some sites have practice of regular inspection of their PSI package. I have seen some performing detailed line walk downs every 5 years.
Re: P&IDs Updation
OSHA 29 CFR 1910.119(d) clearly states that when a change affects process safety information, the documentation (including P&IDs) must be updated accordingly. And to assure this, you may have your internal procedures, workflow, and an audit process.
Re: P&IDs Updation
Yes, the reference has to be made to OSHA however CCPS refers to availability of process safety information as well.
Regarding the regular check, I would say that a risk based approach is best to follow.
I recall a guideline document established at our place to periodically verify PSI. However, that was focusing on high hazard areas at every 3-5 years, and utilities every 5-10 years.
This is in addition to having a robust system to update the documents with each change implemented at site.
