Images
The ECU images below are intended to get an idea and to show of which ECU it is. Furthermore, they could help if the question of the arrangement of the components is in the room after too fast disassembly or desoldering. The most frequently asked question in this context is:
"Where is Pin 1?". The photos shown can not cover all of the ECU revisions, so they should be seen as examples.
