Im new to this usenet thing so i don't really know the netiquette
behind it, i do appologize in advance.
So here is the scenario:
2000 BMW E46 323i 4-door with 81000 miles on it.
This noise has been happening off and on for the past year or so and
shops can't figure out what it is.
It basically sounds like a "a tennis ball being hit with a racket but
The popping gets faster as I accelerate but it stops around 40mph.
The noise does not happen when i coast, only when i step on the
One interesting observation, but hardly scientifically tested is, that
the noise went away for a few days and when i went to fill up my tank,
I checked my air(last time i checked was around 2 weeks prior) and it
was at 28psi. I filled it to 34psi all the way around, and the
popping noise came back.
Also, today I will drive it in different gears (its an auto with
"steptronic") and see if it occurs only on particular gears.
Lastly, an off topic question. Has anyone taken out their A/C
faceplace? Do you know how far back it goes or is it just a surface
The reason I ask is, I got the crazy idea to remount the faceplace on
to two hinges on the bottom so i could hide an LCD where the A/C is,
and have the A/C faceplate "pop down" when I want the LCD screen to
appear. Just an idea.
Thank you all very much for your help.
