Problem is on w203 my 2001 cannot enter in any module, w169 also...
w203 my 2004 working very good, w211 can enter at mostly all modules maybe 90% of them, but not in all!!!
I checked all cables between OBD16 and mux, MAX232 installed new, all relays are OK.
Probably one of 16c550 is bad or PLC???
**** SOLVED ***
Check few resistors 100, 102, 100,102, 102 (big ones) on processors board, should be one of them bad. Also check two BCP56 transistors near that resistors...
