Any further fault finding or help to try and get this over the line ... see my install notes in RED from stages 5&6 onwards and additional comments for ease of reading
5 - Remove Redundant Wires from the Stalks Connector T41
The horn will now be operated by the LIN Bus so the brown and yellow wire has to be removed from pin 11 and insulated. This stops the horn sounding when the CCS on/off button is pressed.
-DONE ( Yes the horn stops working from the CCS ON/OFF ) but Horn works from AIrbag
If you have CCS on the stalks, and are not changing them to non CCS stalks, remove the six stalk CCS wires from pins 26 to 31 and insulate them. - DONE tied back insulated.
Remove the black and yellow CCS wire from pin 45 on the BCM connector T73b. DONE ...but why did this need removing
6 - Install the 3 Repair Wires
First Run two wires from the stalks connector T41 pins 9 and 10 to the pedal area. DONE
If you already have CCS, reuse the black and yellow wire from pin 26 or 29 (they are connected) for pin 11 and another disconnected wire (I used the blue wire from pin 31 don't use the other black and yellow wire) for pin 11 (wires from pins 9 and 11 should now already be installed). DONE - I used Ex Pin 29 ( black /yw ) - connected to Pin 11
Pin 9 wire needs splicing into the black wire on the light switch connector. Take extra care with this one as if it fails your lights may go out. DONE
Pin 10 wire needs splicing into the wire for pin 36 in the BCM connector T73b DONE
Pin 11 wire goes to pin 1 of the T10 connector under the battery. I routed it through a blanked hole near the wheel arch, that I think would be used for the bonnet release cable on LHD vans. Then I drilled a hole to get to the T10 connector. The loom I had for the old CCS kit just reached the T10 connector. N/A as I had CCS from the stalk already
Purchased VCDS HEX 2 and applied the coding as suggested below :
ECU01
Byte 05 Bit 5 ( Already set as 1 ) van had stalk control CCS
BCM09
Byte 09 Bit 3 set to 1
Byte 15 Bit 0 ( tried 0 and 1 ) no noticeable affect on mobile phone !
Byte 17 Bit 2 set to 1 ( and also tried set 0 with Byte 29 bit 6 set 1 and 0 ) - no noticeable effect.
Byte 17 Bit 7 ( Already set as 1 ) van had stalk control CCS
Byte 29 Bit 6 set to 1 ( see below )
When coded with above and Byte 29 Bit 6 set to 1 ALL working wheel functions non operable ( loss of radio and MFD functions ) and the horn will not work from airbag .. set
Byte 29 Bit 6 back to 0 and the radio and MFD and horn functions back again... similar fault set up as bullracing in post above ... have you managed to sort your issues yet ?
With Byte 29 bit 6 set 0 or 1 - no CCS on /off or increments seen in the MFD - just an idea but what if I try splicing to T73b ( 17 ) moved from ( 36 )
( Some buttons on either side of the wheel operate ( LHS up/down volume ) and ( RHS MFD and Radio channel change ) so the LIn Bus signal must be good to MFSW ... is it more the CCS on/off control to the ECU .. I have moved pin 29 wire to pin 11 as in section 6.
