Car starts, but dies almost immediately.

I have a 2006 X5 3.0 an my alternator gave out last night on the way home from work, I was lucky enough to have an auto parts store right there so I parked it till this morning. Pulled the battery out and had them check and charge the battery, I pulled the old alternator installed the new one, put the battery back in. Crank up first try got to 1100 rpm and died. Anyone run in to this problem before?

Tried a code reader from the auto parts store, but it wouldn't connect to read the codes

1. How do you know it WAS the alternator?
2. Investing in a BMW code reader is a good idea.
3. Any issues with group straps, IBS, etc?

(I'm unfamiliar with the X53, but HTH)

OE is Original Equipment aka 'BMW Original Parts' aka 'What you buy at the BMW dealer with a BMW label'

OEM is Original Equipment Manufacturer... EITHER the company that made the OE part or.... A part this is identical to the OE part, but is sold by the OEM under their own label


OEM is not what BMW sells

The alternator wasn't charging the battery. The auto part store confirmed the alternator was bad. I think I may have narrowed it down to the MAF. When I un plug it it runs rough, but stays running

sounds like you can be on the right path, but you really need a code reader that reads BMW codes. The best $150 you'll spend if you plan on keeping your truck.

I had this same issue. My solve was the IAC valve. Take yours out. Shake it. If it barely moves and clicks then it's build up with carbon. Look inside. U should see that. Spray carb cleaner inside. That should fix your problem if this is it.
