2014 Mercedes Benz CLS 550 - best car ever! 2nd best car ever, my 1967 Corvette Stingray Coupe with 435 hp.
Still not solved. Local mechanic with top-of-the-line code reader/scanner could find no trouble codes. Chilton's manual is no help either, though it gives a good description of how the 4wd system is supposed to work. I'm hesitant to start replacing components in a hit or miss fashion. Can anyone offer advice?
