Faint sounds from my 540i

[caddad_540i]

Ok, I know I'm new to BMW's, so I'm not used to the sound.
So I'm looking to some of you experience owners for some help.

My 95 540i has some faint sounds that are very irratating for a
performance vehicle. Its hard to nail down the sound. It sounds
like a fluttering noise, or a water pump spinning noise. Being
particular about my car I would like to rectify this situation. A friend
told me that it was just a normal sound for a bmw. Is this true,
does all bmw's make this irratating little sound?

All help appreciated.

Like a dull tapping sound from the engine?
I had those before in my 95 540i

Found the Problem

Sorry it took so long to come back. I found the problem, according to the BMW dealer I have a bad Catalytic converter on the left side, the right is ok, but they suggested replacing it anyway. I would have to agree. The bad part is, $2800 , OUCH!! I'll be looking for some bargain prices for those babies, Would they consider a trade for my youngest child?

Hi


I have also heard that strange sound on an old 525i (e34), but there the owner claimes it is the fuelpump(inside the fueltank) which has come out of position so it touches some bigger parts, so that the sound is amplified... But I don't know..
