Brand new Bosch Engine Management Computer part number 0261207490 as fitted to Fiat Palio and Siena 1.2 16V with the 188 A5.000 engine. Fiat original part numbers are 55186501 or 7784377.
The ECU is self-programming so after fitting to the car when the ignition is turned on for the first time it will code to that car. After that it will only run that car so you must be sure of your diagnosis.
You don't need any specialist equipment to fit it.
This unit is brand new/never been fitted and because of the coding when its fitted we can not accept units to be returned. It is up to you to make sure it is the correct part number,ie the same as is originally fitted, and that your diagnosis is correct.
If you are not sure if it is the correct unit for your car then send me your chassis number and I can check it out.
