F25 n47 no crank no start
Hi, i have f25 2011 in the garage with strange problem. 
From time to time (very rare) car have no crank no start issue. After an hour or so customer start car normally. 

There are couple of faults but two of them are suspected:

- 2A8800 engine speed picks up too slowly in automatic start or no driver detected during starting opetation. 
It logged at time when car want start. Ista says that starter need to be check and replace when needed. But for me, second part of fault is interesed. What if, seat occupacy detection of driver seat is not working propery? And if so, why car start after an hour and not after ignition off and on?

- 930704 cas: undervoltage at input terminal 30<38. 
Ista say that fuse of terminal 30l need to be checked. I was looking for wiring of that terminal but couldnt find anything. Maybe this is not related to that issue.

I try many time but in my garge car start normally.
Guys please helpsmile

If I helped, please magic buttons thx+rep yes yes yes under under under

RE: F25 n47 no crank no start
I would guess that you have an intermittent malfunction in the starter. It just does not engage from time to time, hence you get the first code. Usually you do not need to replace the whole starter, these problems can be easily fixed by replacing some of their components.
