Renault 1.5 dci K9K Vacuum valve solenoid

HI,I own a Nissan with Renault engine( 1.5 dci K9k) , When I drive I hear a hissing from the hood( I think is related to turbo system), I THOUGHT that Overboost is caused by sticky actuator( but the rod is moving freely when I accelerate/deccelerate so this is good)

Cars works fine but no cruise control because that dtc, I am going to replace ev-526 13.5 v part( vaccum solenoid valve) I tested and it is stuck on open. Could be this my problem ?

Second attachment is when vaccum solenoid valve is unplugged.Cruise control does not work in both cases.

Clear code idle engine see if comes back. Possable blown fuse or it is solenoid

weird how you can hear hissing. Turn a/c off!?

It is permanent dtc, no erase, hissing when turbo came up on 2nd gear for example. What fuse ?

No idea but you could for fault code testing 501 5 watt bulb (approx ish too early morning 500ma load)
