PROBLEM AUDI A3 1.9 105 CV 2009 (I can't communicate with the ECU in the OBD)

[Romanoalessio]

Good evening to all Gentlemen,

[ugoboss]

as for the errors in the ecu, it is very likely that ecusafe has cleared the area, dtc in the file for the story that you don't link if you have not done strange things to you on the file, the reason must be another one, you're sure to select the appropriate protocol for that machine.

[Romanoalessio]

Hello ugoboss, when mapping, I guess I haven't made mistakes because I have mapped in 2D enabling me to drive from the driver to the ecm but the problems pensdoci me began to give out after you have used ecusafe because before defapparla L I remapped for a second time why not was! Clearing the area of dtc, the car will not give me errors or have been cleared only errors as you do in diagnosis? With regard to the protocol we had thought of that and I tried with more than one but when I wrong the software me the has warned that selecting the right one, and reading both in k and in the can it always says incorrect security code

[cawadany]

Definitely ecusafe has paved the DTC. Try to write the original file with the recovery mode.

[Romanoalessio]

I tried cawadany but I always security code wrong :-(

[CLAUDIO.]

Try to read escrivere with another tool

[sisco]

it is not that inadvertently when you have processed the file with ecusafe you put the cue on protection?

[sisco]

sorry I thought now that you can't download the images, however if you open ecusafe see that you can protect the file, and from what I heard it seems that after this protection, you will not leave more to read, I do not know, however, if it can also be the cause that it does not come in diagnosis

[dragusdrake]

if you've stuck with ecusafe you need to open it and read in bdm

[Romanoalessio]

Good afternoon,

sicuraemte was what I did to protect the ecu, unfortunately I'm a novice with cars and this type of work! mistake you learn!!!!! Thank you for the answers ;-)

[cawadany]

In theory you should be able to write it. Try to write without trying to read first. If you try to read, and this fails, the ecu for a certain number of time blocks also the writing. You should leave the picture shot for an hour and then try writing directly.

it happened to me on a golf 5 after about twenty miles that I walked I tried to read and went
pero you see that when it's so off the throttle and the pressure sensor dpf test the car with the plug disconnected

Good evening to all Gentlemen,




good evening ... well, the fact that will give you the diagnosis error trsmissione can , according to me you have some problem on the can line.
So for this you can not communicate with the ecu both with the diagnosis that the equipment to be able to read and write , then, in any case, I would say to do a good check on the can line and see if there is any interruption .. anyway you'll see by the time you read to the bank if the bank tells you you have a wiring problem on the machine .
