Hi there, first time posting on the forum. I just bought a 1996 E230 and I dont know a lot about these cars and no manual came with it. There is a hole where a stalk/stem used to be just above the Left control stlak/stem behind the steering wheel at about 11 o clock. Could some body tell me what used to be there? I'm guessing it was for adjusting the steering wheel, as I cant seem to find anyway to move it. Any help is appreciated.
