Hi,


I have a sitiuation with E87 LCI 2009 116i 2.0L N43 manual
The car cranks, but doesn`t start. it happened when I had to restart it in the car park.
when it was recovered I have checked faults on ISTA and the only one was 2E85 , BSD, message: electric coolant pump: Missing
I cleared it, tried to crank couple times, no luck, the 2E85 came back. the only fault was showing at that point. weak battery was showing some signs too.
So I`ve replaced  water coolant pump, 2E85 disappeared, but car still doesn`t start. recharged the battery too just in case.
now the only faults I get are:
00A6CF JBE: AUC sensor
002EFE DME: Electric fan, activation
but these faults were showing up on this car for ages ago, like a few years, so nothing new it can not be the reason anyway.
all fuses checked and all`s good, tried to clone ECU (MSD 81.2), no changes after, fuel pump live data readings showing up 8 bars or so when I crank the crank, so should be ok.
tried to unplug IBS sensor on the negative battery terminal, no luck.

anyone have any ideas whats can be wrong with this E87?

Does the engine sound normal when cranking?
I have had problem where loose timing chain can skip over the Cam gears and go mechanically out of time. If far enough out, the engine won't start. In my case the engine sounded strange when cranking / was popping back through the intake manifold.
