Hey,
Believe that is the top one (on the side of the intake).
Mainly because I currently have the 2AA9 code for mine that mentions servomotor 2 actuation, and I have confirmed that as the fault by unplugging the one under the intake itself and rechecking the codes.
Easy enough to take that side disa off and have a check. I had a look at mine in the process of disassembling things to get the the one underneath.
