Good Day
I have been lurking around this forum for some time now and have learnt a lot. I just want to say thank your for the knowledge gained .
Background InformationI am working on a 2001 Audi A8 with a 4.2L V8 running on a ME7.1.1 ECU (4D0907560AQ) I no longer have access to the original ECU. This is a euro spec and came with no Evap System. The cluster was faulty and both cluster and ecu were changed. New ECU is (4D0907560AF). I successfully read the eeprom and did a immo delete. By doing this NefmotoEcuFlasher was able to read the flash(see attachemnt for flash bin).I have been trying to do check the bin file using me7check tool but i am having issues with command prompt just blinking and shutting off This has transcended to all command prompt utilities i download and try to run (windows is a pain). I do have access to Winols and Tunerpro. but i do not have any definition files for 4D0907560AF.
The car currently runs but i have the following fault
1 Fault Found:
17881 - EVAP Leak Detection Pump: Open Circuit
P1473 - 35-00 - -
The PlanI would like to remove the DTC and diagnosis/circuit checks for the EVAP system.
My understandingThe following maps needs to set to unsupported of off to remove any DTC and faults associated with the EVAP system.
CDTES - Eurobyte - LDP Diagnosis
CDLDP - Eurobyte - EVAP diagnosis
CLATEVE - EVAP plug
CLALDPE - LDP plug
Circuit diagnostics disabling.
ESKONF-(power output configuration) refers to a group of 7 bytes in the 1.8t, and 13 bytes in the 2.7 flash (iam not sure what applies to the 4.2l v8). In short, these bytes tell the ECU which physical electrical outputs are attached in that particular file. Typically, it's located right above KFKHFM. When removing a component ESKONF is often required to disable circuit diagnosis. Without properly configuring the relevant bit pairs you will get DTCs (Malfunction in circuit, internal resistance too high, etc) due to the missing hardware. Leaving dead hardware attached may prevent these, but isn't necessary when properly coded out.
I am unsure if i need to disable DTC also using this method
http://nefariousmotorsports.com/forum/index.php?topic=567.0I need guidance trying to identify the addresses needed to set bits and disable DTC. Please guide me in the right direction so i can get evap fault disabled .
Thank you
