Hi All, long time BMW driver but this is my first post to this forum on my recently aquired E36 328iC. I searched the webs but its hard to find any similar situation as mine. As the title says, the car makes the tink tink...tink tink... noises when you shut it off like every older BMW I've had. However, this car does the same or similar exhaust expansion noises while driving, all the time, once it warms up. The car is all original, babied by the PO for 44k miles and now by me, pristine condition. Any ideas to check? Thanks!
