Dear MBDoc,

I recently purchased a used 2005 MB c320 4Matic which I've done the following maintainence on w/ a qualified MB mechanic:

oil service
transmission + transfer case fluid change
rear brake pads
valve cover gaskets

6/30, on way to mechanic, car went into limp mode, I stopped and restarted car and it went away. I notice a rear brake failure on the dash readout. Later that evening, I failed inspection for rear brake pressure.
When driving the car, the brakes feel and operate fine.

7/1 My wife calls me to tell me that it occurred to her. I take it to the mechanic and the computer mentions the ESP. The manual says the ESP is related to the traction control. My mechanic wants to put my car online to an expert with the computer system.

What do you think?

David
