Hey Deron, where did you order your cats form. and what was the cost? If it makes you feel better, I have the same startup noise on my 95 il

I know it's not the catalytic converters, it's a pulley or something up front, I have also had experience with the cats about 5 months ago 1,000 miles out of warranty. I replaced mine with after market free flow converters from DEC and they are doing fine.


It sounds like the catalystic convertors are breaking up.VERY common.
Avery 740 I have had had the same problem.

I have a 95 740il with 97,000 miles on it, whenever I start it with the engine cold I get a clanging sound that sounds like a bad pulley or the fly wheel, or maybe even the harmonic balancer. Has anyone had this problem on cold startups?


I have a 95 740il that makes that sound when starting up very cold. Have no idea what causes itbut would also like to hear from someone who knows.


I have a 2001 740IS and the same thing is happening, I was going to take to the dealer but since I read your posts I do not think they can do anything about it.
