How to install a new alternator in an BMW 5, 7, X5 series N62 engine- step by step

[@TheGreendabomb]

This almost makes me feel like i can do this myself.. but it just looks like a long day 😂 Good job on this.

Great tutorial... The symptoms on my car was clear and unmistakable. Alternator was smoking and smelled like burning plastic. Also had a dull squeal as well. finally the generator fault indicator came on.

I have become your huge fan. I have watched mostly all your videos pertaining E65. I have E66, and love watching your videos.

[@ecologicaltime]

thank you very much! Appreciate it

Great tutorial! Just an info that not all N62 engine uses air-cooled alternator. My E66 735Li uses a water cooled alternator which is more expensive to repair/replace.

How to u clip the alternator there’s almost no room

[@jamesrimmer9002]

Awesome Video, very clear and lots of useful tips. Checking voltage at my battery when running is showing 15+ volts, and I'm getting spurious errors, including battery discharge (new battery fitted) and tyre warnings etc, assumed this is the voltage regulator on the alternator providing too much voltage, am I right? you mentioned the power module managing voltage, please explain? Thanks - feel like I can tackle this job after watching your video

Glad it helped. Power module can give errors like you describe. Its a box near the fuse box in trunk if its a seven series. If i recall, it goes, alternator to power module, then to everything else that is electronic. Starter i dont think goes through power module. There is a diagram for this: v12.dyndns.org/BMW/BMW%207%20(E65-66)/04_E65%20Power%20Module.pdf Also did you use same battery or is this new battery?

[@jamesrimmer9002]

ecologicaltime Thanks, it’s a new battery and it’s the same one. I have coded it into the car. The alternator is off at the moment waiting on a new VR, once back together I’ll check the power module if I’m getting the same issues. The old VR is a chimes copy so that’s my main suspect right now. Cheers J

Oh, it’s a 650i not a 7..

normal no water one in n62?

[@tacomanchanic7898]

What were the symptoms on your car before doing alternator.

[@ecologicaltime]

low battery voltage -below 12V. Start your car and if the Voltage is lower than 13,5V you have an electrical problem. Power module does adjust the voltage so wait a little for the module to ramp the voltage up. Takes about 30seconds.

Can any one tell me why if i replace the alternator it started smoking from the alternator?

[@samaelestevez]

Is it the same process for a 2007 650i?

[@yahyashabazz5721]

Yes

[@tacomanchanic7898]

I changed my transmission oil and sleeves on it I then put everything together tried to start my car and nothing. The r n d were flashing. Car wouldn't go into park. Dash said parking brake malfunction. Low voltage . I checked battery it read 12.23 you think it could be alternator

[@ecologicaltime]

if you changed your oil, your car was working when you were filling it up while it was on right?

[@Shas4Ever]

Have you changed the machatronic adapter and 4 rubber sleeves?

[@tacomanchanic7898]

@@Shas4Ever yes I got it running again the plug wasn't connected all the way. But car still shows transmission failsafe program. Do I need to reset that.

[@Shas4Ever]

@@tacomanchanic7898 Reset the transmission error fault using INPA or ISTAD, and reset the transmission valve adaptation.
