Low Brake Fluid?
Hey guys,
I was drying off my engine compartment after a wash yesterday and I noticed that the brake fluid reservoir was completely empty.. well below the min line.
I CAN see a small amount of fluid at the very bottom of the reservoir where it's connected to the brake line.
I don't see any signs of leakage. However, all my pads still have a very good amount of life left so it's not as if the pistons are all just fully extended I wouldn't think.
The car has 23.7k. I bought it CPO at 17k and it had a brake fluid change at that time. That was in August.
Before I call my SA i wanted to see if anybody has any experience with this?

That's odd. Perhaps you have a leak somewhere? Also, I thought I heard someone say that our cars have a brake fluid level warning if it gets too low. If I'm not mistaken they said the warning would show up when they were going around turns (and it turns out their level was fine). Faulty sensor. But I might not be remembering a w204, it could be a different model.
Anyway, none of us will really know for sure. Only the dealer will know, so bring it in. If its still under warranty it should be covered. (At least IMO).

The 2009 C-Class Operator's Manual says: "Vehicle status messages in the multifunction display" -> "Check Brake Fluid Level" is a possible message. So there must be a low level sensor.

MB brake fluid reservoirs (and everybody else's) have been built this way since the introduction of split master cylinders.

thanks for your reply.
Funny, there's this dried (has a texture of dried paint) orange spots on the top near the sensor... Stands out in an otherwise clean engine compartment that was detailed just 6k miles ago.
The second picture is a side profile shot.
