Per the post title, I've got a '97 540i with about 58,000 miles. Just purchased the car back in December '04 out here in SoCal, and this is my first *problem* per se.
I've got a high-frequency rattle coming from what sounds like underneath the driver side. Sometimes it's there, sometimes it's not - but when it's there, it's THERE. Nothing specifically triggers it, it happens under idling (just after starting the car) and/or acceleration. It makes the car sound like a jalopy - which is the most frustrating thing. I understand it won't hurt the car in any way, but I don't want to sound like I'm driving around a POS. :P
I'll be the first to admit, I can't confirm it's my cat, but my buddy (who's worked on them before, alas, on a mustang) believes it to be so.
Now the problem, I've talked to a dealer and a couple other auto parts suppliers, it appears the replacement is going to run me between $1,100 and $1,300 (parts and labor) for one side
Sorry for freaking out, but that seems ridiculous, I can rebuild a motorcycle tranny for less, unfortunately California's smog laws (
ghead )mean nobody makes aftermarket (cheaper) header-back exhaust systems. Ack. Net net net, I just want to see if there are any specific tests I can try to confirm it is my cat
Any help is greatly appreciated.
Oh, and happy belated St. Patty's day!
