Any idea what this noise is?

[CitizenKane]

You know that phrase throwing good money after bad.......how many thousands are you into your 3 series now? Would you be willing to put another €1k into it?

I hate to say it Mr Kane, but I think you do need to cut your losses at some point. Sounds like your 318 is more expensive to maintain than an M3.

Just buy the M3 already! Life’s too short

I like the way you guys think. Is there any chance I could get you to explain this logic to my wife??

You're right I don't want to throw any more money at it if I can avoid it. Tbh this noise is less of a worry than the perpetual oil leak that I can't seem to find...
