2000 X5 won't start? Please help, I need to go to work!

I concur with Term. Again, 4 Runner may not be able to produce enough juice especially if you have a 4.4. It has a 180amp alternator. A lot of juice is needed.

In any case what do you have a 3.0 or 4.4? And how many miles.

Check how many volts first and get back to us.

Right now, the scenarios might be a badly discharged battery, the starter is in a section where the contacts are not engaged, and the key is shot. Which I doubt because if the key was in the vehicle on posII, technically the key is already charged.

There are multiple models, engines, transmissions, and changes during the production run.

Help us help you better by creating a signature that includes some details about which X you have and when it was built (model year/build date) etc.

For example, the top trunk lid lock is different based on build date (I think somewhere around late 2003)...so check any of the part databases like realoem.com or bmwfans.info to make sure you order the correct part for your X.

Always wanted to Quote Qsilver7. LOL

Some X requires new battery to be coded. Get a new battery installed and go from there.

Ok, if I followed the procedure correctly, I have 11.3 volts currently.

The x5 is a 4.4, 143000 miles.

I really appreciate the help here guys, this is driving me mad!!!

Not enough to start. 11.3 is too low. You may get lucky on 11.3 but anything under 11.9 usually means a no start.

that is why a donor car on high RPMs might be able to crank the X, as its own juice is not enough...

With the 4runner attached with jumper cables, I have 12.5 volts, but it still won't crank.

Any other suggestions? New battery? More charging? I don't have access to a bigger vehicle to jump with.

Do you even know how old the battery is? Could be the battery is way past its prime and the draining of the battery by the wife was the final straw that broke the camel back. After 30 hours on the charger that battery should be over 12 volts not unless you have one of those wimpy battery tender charger that can't charge a dead battery.

did you try to hold the RPMs with the 4runner and then start the X? did it work? or not?

I vote for New Battery.

[Gangster_Elmo]

The battery is a white BMW battery, so it could be the original (13 years old), but I have only had the car for a year and don't know the history at all. We have never had a battery problem, but that doesn't mean much. Should I try a new battery for it?
