Hello everyone I have a question for you: I have a Audi A4 2,0 140cv 8v(b7) edc16u31, which often have starting problems due to an error in the ABS caused from the engine control unit; in the audi, they say they replace the ecu and now I would like to know if you should find a ecu with the same HW and SW number Bosch or if any ecu scodificata total to put in motion the car? a BDM I can write the flash ori scodificata on the ecu used?
thanks for the tips.
which errors do you have? do a test with hair from a body shop and a refrigerant spray(the search failures)to see if the defect is accentuated by heating or cooling the ecu, in the vicinity of the flasks, if it is confirmed replace flash.....
I P0522 and P0722....that is the ecu I know and is safe...even audi have done of the evidence....only that I wanted to understand what the ecu to find....I have no way to replace the flash to me is more convenient to change the ecu because I can find no problems...
search on ****** with the number bosch 0281..... etc!!!
What is a hare? A rabbit Abarth
sorry I don't follow
You have said that it is a edc16u31, then you have to find an ecu that has at least the same HW bosch, that is the number that starts with 02810...... then you can reprogram with a file that has the same sw that you installed and try it.
ah here then is the number bosh then HW is the same the one thing that can not be ignored.....so if I were to find the same number as bosh but for example, instead of finding the number of 03G906016KN I find a 03G906016gn okay?
sorry guys but it is possible that there is a compatibility between the various ecu? for example, I try bosch 0281013293 may not be able to use a bosch 028103292? there is a table of compatibility?
Maybe it is and maybe not...
To be safe better to have the numbers, HW the same.
Anyway, P0522 and P0722 not, and who do not start the car. Can pero indicate issues with the ECU, but after you have controlled everything.

A different number of times does not imply anything ****llo HW, but other times they do change things. You should open it and see if the inside is all the same. At the end if it is equal you can do the transformation.
