I don't want to disable the entire gateway, i was asking for clarification of how the instrument cluster utilizes it.

You are not disabling the entire gateway, the code is there because the instrument cluster does not send any CAN messages to the ECU, while the ECU expects them. It still works the other way around. Just look at the FR once, is it really so hard? |

CW_CAN_S.
Send and Receive.
Yes, it's /that/ obvious, which is why any time people ask for clarification on this thing, it is pretty obvious to me they haven't bothered looking.
There's CAN_S, CAN_R, and CAN_C, I was talking about CAN_C. S and R are pretty obvious, but C has no description and references communication with the brakes, allrad(wheel?) and transmission. |

You can ignore _C, it is only used if something is coded incorrectly.

so CW_CAN_R.5 = 0 tells the ECU not to expect any signals from the cluster?

here's what i do see for m-box at least:
cw_can_s_0_a 0x12C80 default value: 255
cw_can_s_1_a 0x12C82 default value: 255
cw_can_r_0_a 0x12C7A default value: 32
cw_can_r_1_a 0x12C7C default value: 36
cw_can_r_2_a 0x12C7E default value: 100
cw_can_c 0x10191 default value: 69
please enlighten. heh

cw_can_r_0_a 0x12C7A default value: 32
If i had to guess, this would be bit 5 of CW_CAN_R |

Weird,in the TT damos the 3 can_r values are the same, but they're different in yours which doesn't really make sense. Also, what's the difference between Bremse 1 and 3?

cw_can_r_0_a 0x12C7A default value: 32 - 0010 0000 bit 5
cw_can_r_1_a 0x12C7C default value: 36 - 0010 0100 bit 10, 13
cw_can_r_2_a 0x12C7E default value: 100 - 0110 0100 bit 18, 21, 22
Unfortunately, the FR only defines the first 16 bits, of which: 5 - Kombi 1, 2, 3 10 - Botschaft Fahrwerk 13 - % CANSEN |

Okey doke, so lets amend that to EACH being 16 bit: cw_can_r_0_a 0x12C7A default value: 32 - 0010 0000 bit 5
cw_can_r_1_a 0x12C7C default value: 36 - 0010 0100 bit 2, 5
cw_can_r_2_a 0x12C7E default value: 100 - 0110 0100 bit 2, 5, 6
2 - Botschaft Bremse 1 5 - Kombi 1, 2, 3 6 - Botschaft Allrad 1 So, which variant is the one in use? or just clear bit 5 in each: cw_can_r_0_a 0x12C7A 0 - 0000 0000
cw_can_r_1_a 0x12C7C 4 - 0000 0100 bit 2
cw_can_r_2_a 0x12C7E 68 - 0100 0100 bit 2, 6

CW_CAN_R_0 is referenced directly and offset by a byte variable. The byte variable is the sum of 0x81ED77 + 0. In the M-box, 0x81ED77 is 0.

Thanks phila.
Anybody want to test this?
Should be easy to do, just unplug the cluster and see if the ecu throws the code.
