Central Locking ECU

[waue1978]

Does anybody know where this is fitted in a D9 estate? I've searched & can't find where it is. After going through all the hassle of changing the faulty rear door lock, my central locking is still playing up intermittently. Disconnecting battery following the 3 minute rule didn't work, so next plan is to change the locking ECU, but want to find out the part number before ordering the wrong one.
