i try read sid803 bdm, but problem is when i connect 12V to ecu mcu is heating up to 55C, i connect 5 wires directly to board, but gal2 cant read always get error ... is it possible that i make something wrong and damage ecu, or 55C is normal temperature?

Wrong connected ,ecu is dead now i think.

in siemens ecu there should never be 12v on BDM pads, only on ecu connector. that way even if you connect something wrong on bdm connector you wont kill ecu. but if you accidentally put 12v on some of bdm pads, it is very likely that ecu is dead now

i not konnwct to bdm pad 12V only to pins ... but i make a mistake and exchange left and right side of bdm connector, so pins i must connect to left side i connect to right side ...

maybe i connect to bad point GND, DSCK, DSCO, DSCI, PORST but not connect 12V to bdm

Few years ago I did the same mistake like You ,and result was also the same ,in the end I had to buy second hand ecu and swap eeprom for immo ,then with proper connection my BDM did read this second ecu without any problem.

HERE is a tool (http://carexperttools.com/locksmith-tools/i-o-terminal-basic-v2) read write siemens ecus by obd or on a table by can or k line, no need to open ecu.
