[Alessio93]

what unit are we talking about ?

ecu bosch ME7.3.1

[amen]

1. Disconnect the connector (A) from the ecu.
2. Remove the plastic cover on the connector (you should then see the wires entering the connector.)
3. Locate the pin 20, which is usually an empty hole without thread.
4. Stick a wire into that hole, even a piece of tin, with me it worked
5. The other end of the cable, connect it to the ground, even the casing of the ecu
6. Connect the connector on the new ecu
7. Do all transactions via obd
8. Disconnect the additional wire at the end (otherwise the machine will not start).
Note: after you have connected the cable from the pin 20 to the negative, turning the key to MAR, the warning light code should light up, it means that the machine is in the boot
