BECM fine but battery draining

I know its been covered a million times befor, and ive read what i can from searches. My battery dies if i leave the P38 for any longer than a day, but the battery itself is fine, ive just tested it. Ive also tested the BECM, to make sure its going to sleep, reads about 20-30 mA of drain after a couple of minuits of locking the vehicle. Also i belive the light on the shifter is a teltale of this working, and it goes out the same time as the drop.

Is the drain possible because the BECM is being woken up by wi-fi's, there are loads around, including ours. If so i need to disconect the antenna from the BECM, i understan it in the boot on the drivers side, and there are two wires. My question is which wire do i disconnect? Apparently there are two plugs; a plug with one wire and a plug with three wires, but i cant find anything specific on here.

Thanks, Rich.

one wire plug is the one you want to unplug..

Or get an updated reciever.

Disconnected mine yesterday.......my single wire was blue and went in the direction of the window.

Yea went up one of the pillars. Remote seems to work same as before. Will see if it makes a difference.
