Where is the alternator fuse located on a 2006 BMW 330I?
If the alternator is charging the battery it will not be the fuse. The alternator would simply stop working if the fuse has blown.
If the battery isn't holding charge you might have a power drain somewhere in the vehicle. Something in the electrics may not be turning off correctly and draining the battery. Do you have any warning lights on the dash? Have you access to an OBD2 scanner to check for any Trouble Codes?
If it is a power drain the simplest fix is to get a good Auto Electrician to check the vehicle. Finding a power drain or an electrical short can be a real pain in the tail bone job because there is so much electronics on a car. Paying an expert to do it is a lot quicker and easier as they have the right tools to do it.
2007 BMW engine light with code P0304.
It is one of the two. First thing is to remove and check the plug for gap and condition. Then reset the code and run the vehicle. If it does it again, you swap the coil pack from Number 4 to Number 1. If the misfire them moves to number 1 you know the coil pack is the issue. Sometimes just moving it will fix the issue as the connections get remade.

BMW E46 ZF 5HP19 trouble code P1732 P0733 P0734
Yes, this could be the shift solenoid. Was the transmission filter changed at the same time as the fluid? Dirt in the system can affect some of the transmission sensors tripping Trouble codes. I cannot be sure what the P1732 code is as some codes can be very vehicle specific but it appears to refer to the transmission or on of it's sensors.
P0733 - Gear 3 Incorrect Ratio.
P0734 - Gear 4 Incorrect Ratio.
Lost radio code, how to reset, 2003 BMW X5 E53 4.4 please?
If you take your registration ducument to a BMW dealership they will tell you the code for free, based on the VIN number.
Or look in the Glovebox for a small white sticker, or in the Owner's manual.
But, I found this
BMW hasn't used a "radio code" since the beginning of the e38/e39/e53/e46 generation of BMWs. That technology ended with the anti-theft radios used in BMWs prior to the aforementioned e series.
The code you see appearing on your nav screen or MID (you didn't indicate which radio setup you have)...is an anomaly of the OBC's immobilizing code probably brought on by the low voltage issues you were having. There have been many threads on this topic across multiple BMW forums in that usually a simple use of "0000" or "1234" works to get past the lockout once the battery issue or low voltage issue is fixed...or initiating the emergency deactivation of the CODE found in the owner's manual.
and this confirms it is the immobilizer code
