How long before you start hearing the pump whine and it finally failing?
I noticed yesterday when some 20 feet away i could hear it.
Externally loudest from under the right side rear bumper and in the cabin a like a low AC electric hum.
Machine i used i reinstated as no one could get it to work properly.
Needed some fiddling and experimenting.
Various cuts can be programmed in.
Set the machine off you have a wire cut every 2 seconds.
That can be a lot of ruined wires!
No definitely a wire cut, as discussed years ago.
I have used such a machine and seen the same mistakes.
I think someone measured to the plastic housing, got it wrong and moved the cut to the switch, for soldering.
Funny about broken wires, friends Tesla seems to have the same wire as our Zed roofs.
Breaking in the connector bellow to door, in his case stopping rear door opening.
