In Reply to: SOS!! LOUD uncontrolable noise from e-box 88'735i posted by jim on April 02, 2001 at 16:31:56:
But David is right. Your car alarm horn was active for some strange reason.
Always carry tools in your older e32's!!!
Heres one for the books:
In my morning commute, in my 88'735I-(automatic trans. 188,000 miles) after about 8 minutes of driving (3 minutes on the freeway) I heard a VERY LOUD noise that sounded like my Horn was stuck!!! I pulled off the freeway, and turned off the car and when I opened the drivers door, the noise was comming from under the hood. It wasnt the horn, because I could still honk the horn (although you could hardly hear it over the constant howl from the e-box)
When I opened the hood, the noise was deffining, and definately comming from the E-box, which was vibrateing to the touch. Still thinking it was the horn, I pulled the horn fuse to no avail. Unfortunately I did not have my tools, or I would have disconnected the battery lead right there. It seemed like nothing I could do would stop the noise.
After about 8 minutes of trying things, wakeing up 4 square blocks, and scratching my head, I decide to try to find a local garage, since the car was still driveing fine, I got in,
Started the car, and as I put it in drive,
the noise stopped.
Its been a week, and with minimal driveing (maybe 50-75 miles) it has not done it again.
When I pulled the ebox cover...everything looks normal, and of course, the bently manual does not mention this.
Was this some kind of alarm?
What could have possibly made this noise???
I hope nobody ever has to go through this embarassing experience.
Any advise/comments are appreciated.
