Must be something wrong with the wiring, but I can't figure it out, and neither can the yard. Any ideas?
I have installed my X5 today and I had exactly the same problem, it would not stay in AUTO and go to STANDBY wihout any reason or warning. Once it happens it is not always possible to set to AUTO again. It would sometimes go to START UP message and hangs there.
I suspected electrical problem at first, replaced power wires with heavier wire, added ferrites on power and network wire, on both ends, added grounding wire (heavy braid).
The system started working. I thought I had it fixed, until I saw your post.
Come to think of it now after reading your post, by the time I was done it was almost 7 p.m. and temperature had come down from 85 to about 70. No wonder, if it is temperature related, it is quite possible that all the wires and ferrites were not useful.
I will see if it does it again, if it does I will take the board out and set it up on a bench and blow hot air at each component separately.
You can tell when the system "goes to sleep" - the two indicator lights next to the processor start flashing regularly. Normally they are either off when in "normal" standby, or flashing sporadically when the motor engages.
