Mein Auto: 2004 X3
Long crank to start part II

Did anyone ever come to a final conclusion as why their X3 had a long crank time to start? My 04 has been all over the map. Fires right up. Other times takes 3-4 seconds. Yesterday on 3 different occasions it took 7 to 8 sec and once it didnt start on the first try.

I had the fuel pump replaced a couple of weeks ago. I initially thought it corrected the problem but within the last week, much to my dismay, the cranks again have become longer.

There is NO pattern to it. Hot or cold. Pausing the key, nothing makes a difference. Sometimes fires right up, other times not. I dont get it? All I can find on the forums is Crank position sensor, or fuel injectors getting replaced ($$$$) or the fuel pump.

Anyone get a real fix for this?

My sister n laws 04 X3 fires right up everytime. Which tells me something is not up to speed on mine.

Thoughts?

Mine did this right before we sold it, it ended up being the fuel pump on ours. It did the exact thing you are describing. Gotta see if I can find the invoice and see what exactly they did.

there is actually a tech bulletin for this problem. software update will fix it. it's SIB # 12 49 06

This Service Information bulletin supersedes S.I. B12 49 06 dated November 2006.

Important: Do not replace the throttle body for the throttle faults, stored in conjunction with FC28B2,
even when the test plan recommends to do so.

Well they had to replace my disintegrated fuel pump first.

Then it spent a month in the shop trying to get that bulletin right.

It happens to me from time to time, maybe 2-3 times in a month, but since none of the lights are on I don't think this TSB would apply in my case. And is not getting any worse, so right now is not to the point that I would consider it a problem.

+1, same here. Happens intermittently (3-4 second crank) with no lights on dash. I am thinking mine would be batteries, they are 5 year old now; drained once in winter and needed boost.

My 05 330CiC does this. Has same engine. Letting the key sit in the on position until a second after beeps stop is the only way to get it to start almost instantly. Otherwise its random amount of cranks.
