Strange Noises after 1200 Mile Service

Hi,

Just had my 1200 mile service done yesterday. Immediately after leaving the dealer I noticed the car 'felt' different. The intake / induction sound seems to be slightly lower pitched and resonates quite a bit more...almost feels a bit gritty now...more of a moan/groan than the nice harmonic-ish intake sound. Also, most concerning, is that during light throttle between about 2k-3k rpm there is a chattering / ticking that the engine is making...it almost feels as if something is loose in or around my engine and banging around.

Called the dealer and they will take a look tomorrow....I'm hoping this is not going to be an extended stay....anyone else have this happen?

before my 1200 mile i had a very noticeable whine in 7th gear between 3000-4000 rpm that went away with a flush of the fluids. as for your rattle at 2-3k rpms, i have that too, think some guys have it, some guys dont. god i love the s65. that rattle is not a big deal, in fact i think it may actually be vibration knocking around the vent on top of the hood (i believe the one that actually has a use, so as you face the car the vent on the right)
