Car having issues...
Today I got up and went to the store, now it has a really weird whine coming from the front of the car, it rattle a bit and smells funnny.
I uploaded a short youtube video. Any ideas? Think I can make it to the dealer or should I have it towed?

Remove the engine cover (front half), start the car and watch the belt and all the pullies. If you don't see anything obvious, then remove the belt and spin all the pullies by hand.

If not the tranny will need to be rebuilt. Hard to believe at only 72K. Car has been trouble free up till this point, but I will be selling it if it's something major. Love the car, but **** that noise at this mileage.
The noise stays constant with the RPM of the engine. You can hear a rattle under the car as well.
EDIT: belt looks new still.

Do you have a CEL? Does everything work? Get someone to check for codes.
With that much noise the source should be easy to identify.
Good luck!

Why does the engine look like crap? Garden, lol, its a few leaves. Not sure where you live, but leaves have been falling like crazy here so even when I clean them out within a few days there are back. I drive my car A LOT, put 35K on it in 8 months.

Was the transmission serviced at 39K? Oil & filter change?


I've never heard a Benz transmission make a noise like that but there is always a first time.
The noise sounds more up front to me but recordings can be deceptive.
The 7G had numerous software flashes that fixed jerky changes. Mainly jerky downchanges.
Start by checking the fluid level as others have said. Also, if the fluid looks really dark (like black) it may be worn out you may need to have it flushed and replaced with new fluid. My wife's Odyssey van made that same noise every time it got cold, even though the fluid was up to level. I replaced the fluid and the sound went away.
