coolant smell coming from engine bay
Buying my C32 earlier this year I'm still a noob to MB. I haven't had any problems with my car other that bad seat modules causing S/C shut off, but recently I've been smelling a sweet coolant smell coming from my engine when the car is running.
I've looked for obvious leaks from the hoses, I/C pump, radiator, water pump, but I couldn't find anything noticable. I did put coolant in it about a month ago but it hasn't gone down since then. Also the car runs ok but I there is a noticeable rumble coming from the exhaust that wasn't there before
. From the experienced C32 owners has anyone had coolant issues? Any advice would be greatly appreciated.
Thanks again
Jorge
