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

[Romanoalessio]

Good evening to all Gentlemen,


unfortunately, I have a nice problem with a AUDI A3 1.9 105, in the past I've mapped the ecu and removed the DPF with ECU SAFE, after about 5000 km, the car problems in acceleration, or as soon as it goes in a couple off the accelerator until the release, but not by any error in the picture when it happens!!!!!!!!!!!!!!confused I thought it might be the potentiometer, gas, or some problem to injection, but when I try to enter the diagnosis gives me error transmission line CAN!!!!!!!! (I COMBINED A BEAUTIFUL MESS) I tried to rewrite the original file but nada software k suite answer me incorrect security code I don't know how to solve the problem you could give me a help please

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.

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

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 :-(

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 ;-)
