brake fluid question

I was told that I could expect problems with my 2003 E 320 with brake fluid leakage in a control panel box on pass. side inside the engine compartment. Is there an engineering defect that might cause the computer inside this box to short circuit? Any information will be appreciated. Thanks, Tramore

With the SBC system there was many flash up dates for the control unit, and if you hear any funny noises that sound like coming from under the hood there is a hose that needs to be replaced. you should take it to the dealer and make sure all the latest up dates have been done to it. these are recalls so they should be done for free
