Hello guys,

I am looking for fault memory lists including the UDS identifier for VAG (Especially VAG MQB).

Does anyone have something or know where to start? On the Internet, unfortunately, you can find so first nothing. Only the VW error code + error text but no conversion to the UDS data.

If by UDS identifiers you mean the DID 2bytes hex address on simos18 you will find all of them inside the file.
On med17 you will find some of them(mostly services) as the rest are hashed into a ram table.

I do not get the diagnostic codes question though...

Well I mean the 3 byte Identifier given From UDS Service 0x19

Here a Log from SIMOS18:

Code:
4; ; STD    ; 000007E0; 8; 03 19 02 2C 55 55 55 55  ; ...,UUUU
5; ; STD    ; 000007E8; 8; 03 7F 19 78 AA AA AA AA  ; ...x....
6; ; STD    ; 000007E8; 8; 10 2B 59 02 FF 00 40 44  ; .+Y...@D
7; ; STD    ; 000007E0; 8; 30 00 00 55 55 55 55 55  ; 0..UUUUU

9; ; STD    ; 000007E8; 8; 22 7E 20 00 4D 8E 20 00  ; "...M...
10; ; STD   ; 000007E8; 8; 23 56 27 20 00 4D 9C 20  ; #V'..M..
11; ; STD   ; 000007E8; 8; 24 00 4D 9E 20 00 4D A3  ; $.M...M.
12; ; STD   ; 000007E8; 8; 25 20 00 54 98 20 00 4D  ; %..T...M
13; ; STD   ; 000007E8; 8; 26 A7 20 AA AA AA AA AA  ; &.......

DTC's:

0x004044 Status 0x20
0x00431A Status 0x20
0x00547E Status 0x20
0x004D8E Status 0x20
0x005627 Status 0x20
0x004D9C Status 0x20
0x004D9E Status 0x20
0x004DA3 Status 0x20
0x005498 Status 0x20
0x004DA7 Status 0x20

Now there is a Table between the CAN-DTC-Error-Code and the VAG-Error-Code + Description

Look inside the file...you will find almost everything you need there on simos18...

A hex editor with search capabilities will show you what you need..

I'm not sure which file you talking about. If I extract a FRF I get a ODX.

If I split them into binarys I get Binarys for each flash block...

Find a diag PDX/ODX file and dump the data.
FRF is a flash container, it has a flash ODX, not a diag ODX.

Easier said than done unfortunately! Any hints?


Code:
004044 -> U041600 - Invalid Data Received From Vehicle Dynamics Control Module
00431A -> U112300 -Databus error value received
00547E -> U016400 - Lost Communication With HVAC Control Module

005498 -> U100300 - Towing recognition control module No Communication
004DA7 -> U014000 - Lost Communication With Body Control Module

Exactly!
