EGS transmission control solenoid valve 3 (interlock)

[micky1786]

Hi all fitted a replacement mechatronic unit to my 525i 2004 and the transmission fault has now gone but I have a new fault showing as above. Can someone kindly point out which valve is number 3 so I can get this replaced please?.
Fresh transmission oil @9litres and new filter have also been done.

Thank you
