hi there new to this so bear with me,my car was needing a new actuator valve or so ive been told,can do the work myself,but on removal of the actuator the nut thats meant to be threadlocked wasnt! so is it possible that it has moved causing the p2099 code and if so does anybody know what the measurement for said nut is meant to be??

forgot to mention the actuator unit that came off holds a vaccum,is there any other know problems for this code to come on and cause limp mode,which does clear when car is restarted,but will go bk to limp mode if driven over 2000/2500 rpm,will even trigger limp mode if left ticking over for 10 mins or so
