Yes I hear the same sound. It sounds like a faint burble or pop. No idea what it is. I heard it in the first 100 miles and now i have 450

It may be the clutch engaging on the supercharger. Does it happen for a split sec on acceleration? If so, that's probably what it is. It drove me nuts until I forced an MB mechanic to ride in the car w/ me to tell me what it was. I just got used to it.

It's normal for the E55. I had the same ticking sound and asked several service advisors. They said it's normal, something that has to due with the high performance braking system.
