4Matic Light on
Yesterday, I was driving my 1992 300e and my 4 Matic warning light came on. I followed a test procedure that I found online and this was the trouble code that I found. "10-Hydraulic valve 3, short- or open-circuit, OR brake switch defect." Can anyone tell me what I should start looking at? I'm new to this. Thanks
