4SNS/1/40000001:IDOR-0.000
I have Googled, BING'd and otherwise searched the heck out of this error and to my knowledge, its only ever showed its head in Germany! 😕
Anyway, since there does not appear to be any tangible or viable information on this in English anywhere, I thought I would share my findings with everyone here. On a whim, I ran a Hardware Test on my new r-MBP. I say on a whim because I had no problems but had read of other's issues.
The test returned the error 4SNS/1/40000001:IDOR-0.000. I called Apple Care and they had "no idea what that error is" so they made a genius appt for me. Before I drove the 70 miles to my nearest Apple store, I decided to run the test again with the power connected (IDOR-0.00)...you guessed it, no more error.
Bottom line, Hardware Test Error: 4SNS/1/40000001:IDOR-0.000 = No power connected.
Maybe not earth shattering, but it should save some of you who get the same error from getting nervous. 😉
