I TOOK MY CAR TO BEVERLY HILLS DEALER AND LAST WEEK I TOOK MY CAR TO PENSKE MERCEDES BOTH TOLD ME THAT THE SOUND FROM THE ENGINE IS NORMAL FOR C230 KOMP
STILL IT REALLY BOTHER ME IN THE MORNING OR IF THE CAR BEEN SITTING FOR AWHILE,,,,BUT AFTER 5 MINUTES ITS GONE
AND THE SAME NOISE IF I STEP ON GAS PEDAL AND WHEN IM TRYING TO STOP , SO THE NOISE ONLY HAPPEN WHILE THE CAR STILL COLD , WHEN IM ON MY FIRST GEAR TO SECOND GEAR AND WHEN IT DROPEED FROM SECOND TO FIRST GEAR (AUTOMATIC TRANS)

ONETHING I HATE WHEN THE GUY FROM THE DEALER TOLD ME IF MY CAR UNDER 50K THEY CAN MAKE IT BETTER FOR FREE AND MY CAR GOT 50015 MILES ON IT .....................

PLEASE LET ME KNOW IF YOU HAVE THE SAME PROBLEMS AND WHATS THE SOLUTION?

THANKS GUYS

is it like a loud irregular engin hum noise

cause i get the same thing upon startup but it goes away in like 2 min. :P

when i bought my car it was like that, so i didnt see any reason to freak out

i do not have a super charged engine btw

scratch that, its not loud at all
just a irregular hum noise

i only hear it when i cold start and it goes away in 2 min
