Gents,
I have bought my C Class couple of months ago (and i am in love with it).. But wondering if you can help me in those issues ruining my mood every time I drive my drive it:
1- A/C has a squeaky sound most of the time when I brake or corner at low speed.
2- The coolant level warning light is always on although I am always checking it and didn’t find any leak or fluid level reduction.
I would be very thankful to anyone who could help me knowing the cause of those symptoms.
Regards,

Is this a new C Class, the AC noise might be a loose compressor and the belt is noisy or worn, do you have a water temp gauge, is the car running hot over 100C on the guage? If you don't have a gauge and the the coolant lite is on, sounds like a hot engine, better have that check ASAP, The coolant lite doesn't necessarily mean there is a leak, but could also be a hot engine condition.

the coolant level sensor is parallel connected with the washer fluid level sensor.
if the resistance of the washer fluid level sensor changed (defective), the control unit might interpret it as a signal for low coolant level.
if you need more info on how to check it, i'll send you.
it is a very interesting but simple design.
