The workshop manual is much more than will fit in a PDF. There is a CD that MBZ sells, or, you could buy the "bootleg" version of the official Workstation Information System (WIS) on eBay. Better yet, buy the entire Star Diagnosis (SDS) "clone" system . It will run about US$500 and comes with the necessary OBDII multiplexer, software and WIS. Eliminating one or two trips to the dealer for diagnosis will have it pay for itself.
