The Random E46/ZHP Question Thread

I did it on my sister's 330Xi without lifting it.

I'm trying to identify a noise, and any help would be appreciated. 2005 330Ci coupe. I only hear it when the car is just beginning to accelerate, and it disappears after the car has warmed up a bit. It sounds to me like it is coming from behind the center of the dash. If any of you are old enough to remember what the old speedometer cables sounded like, that's the sound. It seems to be related to throttle or vacuum. I can give the car light throttle, and I hear a swishing noise like two metal disks lightly rubbing swish......swish......swish......swish......swish and then if I let off the accelerator, it can actually speed up swish..swish..swish..swish, and after a couple of seconds, it's gone and not heard from again. I also noticed that if I banked the car hard into a turn, I could sometimes induce a little swish..swish..swish, and then it would go away.

I had a few ideas -- CD in radio. Nope. Replaced the NAV unit, still there. Final stage resistor? Fan still seems to blow fine, but I do have one ready to go in.
Automatic climate control module fan? Bad passenger side front wheel bearing?

What do you guys think?

My first thought was the heater fan as they are notorious for making noise but that's more of a chirping noise at low fan speed and would not change with throttle input. Final stage resistor would either kill the fan or make it run erratic.

If anyone comes across a good deal on a battery that will fit our car, please let me know . I wanna try and purchase one on sale before I urgently need one (and therefore not having the time to wait for a deal) thanks!

For anyone that has removed their alternator to swap alternator pulleys, did you bother removing the power connection on the rear?

The positive connector? Yeah. I took the whole thing out of the car so I could shove a screwdriver in it to hold the vanes in place.

I'm kind of a redneck tho.

Can anyone point me to our Monroney sticker thread?

so i'm looking to replace both the main accessory and A/C tensioners as well as idler pulley. my question is what is the right part number for the A/C tensioner? do our ZHPs have 4 or 5 rib belts? any help would be appreciated!

edit: NVM, i think i found it. it's part 11287512758


next question: has anyone replaced the A/C tensioner and belt without lifting the car? i watched a YT DIY video and he has the car jacked up, but i am wanting to know if i can complete the job entirely from the top side. thanks!

Top side is fine. The tensioner for the A/C is easier to get to underneath, but it isn't hard from the top.
