Hey how are you

1- did you use a basic code reader or bmw factory scanner or equivalent and it came up with no codes .

2-was alternator like advance or auto zone one , did you check the rated amp on the one installed & does it match original

3- the alternator installation needs rechecking ,for backed out pins on electrical connector,burned pins making poor or interment connection,loose ground

Please let me know

Thank You

The alternator only checks out when i park for 1 hr and run the engine , the car starts the second or third time i turn the key, sometimes i have to give it gas for it run, but sometimes when it turn on the rpm is near zero and the alternator is on , when i give it a slight gas pump the rpm rise to normal level and the alternator turn off.

Do you think it could be the connection between the alternator and the batterie?

I took it to many garage they all tested the v and told me the alternator was ok

then you have to go to ECM & Ip cluster ,let them check these connection and do a continuity test on the harness if that check out these it will be between ecm and IP cluster ,I can not confirm it for you, testing will be needed

You are very welcome :)
