TL12V2 "pressure relief valve" error code

[LobsterMobster]

End of the day today my TL12V2 had an alarm and this code:
spn 523606 fmi 2

Manual says that's DTC P2293

Manual says pressure relief valve error. Manual doesn't say anything about it, but anyone dealt with this before? 2019 machine with 1470 hrs. Did a service on it a few days ago, new hydraulic fluid and hydraulic filters, final drive fluid.

I was using a bucket attachment and a trailer hitch attachment moving a loaded dump trailer today.

Update: after a few hours of research I think it's the pressure relief valve on the common rail. Takeuchi wants you to buy the entire rail, no part number for the prv. But if you search for kubota v3800 common rail prv I found it at Friday parts
