Title: Question about ME7.5 coding 0011711 and 0011581 BEX (swap ecu) Post by: black on September 28, 2015, 01:15:24 AM Hi,
I know 2 BEX ECUs (8E0909518AS) with different codings on. 0011711 and 0011581... All BEX should be only manual transmission cars but I get fault codes after swapping BEX ECU 11581 to AVJ 11701 car: 18320 - Pressure sensor for brake boost (G294)- P1912-01- short to plus 18034 - P1626 - (Data bus: missing message from TCU) 17837 - P1429 - Circuit for Brake Vacuum Pump: Open Circuit. I think the brake codes can be coded out because AVJ has no electric brake booster but the TCU error is maybe VARDEF related?

This ECU has coding 011511. In BEX file I can see the codings starting at address 02cb04 02cb10 - 11511 02cb12 - 11711 02vc24 - 11581 11xy1 x= 0 front wheel drive without ASR/ESP :P 2 four wheel drive without ASR/ESP 5 front wheel drive with ASR/ESP :P 7 four wheel drive with ASR/ESP y= 0 - 5 gear manual 1 - 6 gear manual 5 - 5 gear automatic 8 - multitronic ::) Title: Re: Question about ME7.5 coding 0011711 and 0011581 BEX (swap ecu) Post by: nubcake on July 14, 2016, 04:08:56 AM CWGC, CW_CAN_R, CW_CAN_C

i've got almost the same problem with my Audi A4 AVJ. I am flashed 8E0909518G 0261206879 1037396893 but before i did that i set CWGC to 15 and VARDEF to 11501 but i still get P18034 (missing comunication to Transmission(SG)) and my ABS and ESP lights are showing. No softcodings in VCDS available. Is there any solution to get this fixed? Written file is attached.

This soft is only for cars with multitronic CVT. Before to flash think what you do.

CWGC was set to hex 0x15 instead of dec 15. finally everything is running fine. |
