Ive got a AUQ 1.8T 032HN thats been chopped into another vehicle, sorted out most of the fault codes, but Im stuck with these in the Engine ECU:
2 Faults Found:
17931 - Crash Signal from Airbag Controller
P1523 - 35-00 - Implausible Signal
18057 - Powertrain Data Bus
P1649 - 35-00 - Missing Message from ABS Controller
The cause of the issue is obvious, I dont have ABS or Airbags, but it would be nice to code these out, the current softcoding is 11510 - I cant find a coding table for this ecu, before I trial and error, does anyone have any info on this?

Cheers, thats certainly an option, but I would prefer to code them out, rather than editing the error classes so they dont get thrown.

If you read funktionsrahmen. I think you can use cw_can_r.

CW_CAN_R is useful for the missing message, but the other one, I'm not sure about. You can certainly error class it, but there is likely a better way.

Regarding CW_CAN_R There are more words R_1, R_2 etc. On the file I was looking at (06A906032HN 0002)they all had the same data in 0x00AC which I have worked out what it means. But there was nothing to say what each of the other locations do. Do they all do the same thing?

I get these aswell. Would be nice to find a way to get rid of them. Got them coded out from the cluster via the CAN module

The additional variants are just that.
For variant coding.
You can see which one is used for which coding scheme if you look at the bits and how they're set.

Any other solution for 17931 DTC? I am sure I located all CW_CAN_R variants correctly as 18057 is gone - all 4 changed from 0x00AC to 0x0020.

Found it already but thanks for the answer.
If I understand correctly funktionsrahmen we should not clear airbag related CW_CAN_R bit if CWCS is set to 4 or 8.

But i canon't find CW_CAN_R on my 1.8T ECU  SoftCod:11001 I will appreciate any help, I read all topic that search can provide, but still i can't get it how to find CW_CAN_R in 1.8T ECU |

4B0 906 018 CG
Comparing to some others bin, I think I located CW_CAN_R at
0x136E4 Hex:0x28
0x136E6 Hex:0x3C
0x136E8 Hex:0x28
0x136EA Hex:0x3C
CW_CAN_C
0x1019D Hex:0x05
set all this values to 0x20
But didn't make any difference, stil got
18014 - Rough Road/Engine Torque Signal from ABS
P1606 - 35-00 - Electrical Malfunction
17931 - Crash Signal from Airbag Controller
P1523 - 35-00 - Implausible Signal
18058 - Powertrain Data Bus
P1650 - 35-00 - Missing Message from Instrument Cluster

Okey I think my CW_CAN_R is located good. When I set values to 0x00 i get rid off this DTC 18058 - Powertrain Data Bus P1650 - 35-00 - Missing Message from Instrument Cluster Obviously on ME7.5 P1606 P1523 are not connected to CW_CAN_R, so I need to dig further. To explain others, this how CW_CAN_R looks like. In my case i need byte 5 set to zero so 0x3C set to 0x1C, and 0x28 to 0x08 Edit: only when I set CW_CAN_R to 0x00 i dont have cluster DTC. I set i to 0x20 have cluster DTC, set it to 0x1C/0x08 again have cluster DTC. What doesen't have any sense  |
