My power fold works with me sat in the van, ignition off, key out and doors locked. I didn't check to see if that was permanent ie. battery saver locks out after 30 mins or something, i may check sometime.
It suggests that a simple timer relay circuit may be used and link the windows/mirrors/deadlocks so that we have windows without key and mirrors fold on deadlock.
I thought about mirrors fold timed without key might work but the drawback would be that you might want it instant on deadlock?
Also, without a further enhancement (lockout) of the circuit after first deadlock, every time you press the deadlock button on the remote it'll open or close the mirrors, might be a good or bad thing I'm not sure yet.
Lastly, i haven't seen the mirror module or door licking/windows modules so i can't say whether there is a simpler solution ie swapping for a Mondeo 1?? Someone else suggested that.
(I am guessing that they are powered differently on Mondeo and have different can bus arrangement?) Transit power strategy shows live to mirrors which seems similar to the mk7 but that's all I've seen, can bus staying active??
Need More info.
