Hello all, Is it possible to read the ECU codes on a 97 W140. I already have a generic VAGCOM OBDII cable for use with my Alfa Romeo. Is there an internal OBD / EOBD port for connecting to? Or is it possible to make the codes flash out on the LCD dash like in some cars? Ive also read its possible to somehow interrogate the A/C unit, as mine is not blowing ice cold id like to connect up to it and see what the diag says. Thanks.
