XZBMW  BMW F31 seat heating retrofit
Hi Guys,

I retrofited front L+R seat heating on my F31 and want to code it with ENET Cable + Esys 3.27.1.
I expanded FA with VO code 494 and coded it, after that i recoded FEM_BODY, IHKA and REM.
My problem is, if i connect the new air con panel with seat heating buttons, the panel starts to blinking and the buttons doesnt work propertly, which means for example if i push + fan button automatic air con turn on.

Please help

Thanks

Tom

First program the new airco panel and then coded it.

MGU virgin and patching in Europa.

RE: BMW F31 seat heating retrofit
Ok now i get it, all my ECUs are on I-STEP F020-13-03-502, except the new IHKA which isnt compatible i gues. I can upgrade all my ECUs to F020-16-03-XXX, but my CAR is chiptuned and i dont want to lose it due this upgrade.
It is any way to downgrade IHKA to F020-13-03-502 Esys allows only upgrade to F020-16-03-XXX.
Thanks

RE: BMW F31 seat heating retrofit
So i reprogrammed IHKA to I-STEP F020-13-03-502 , i modified actual_svt and set the unmodified actual_svt as target_svt and calculated new TAL, which had following "new" components
BTLD_00000DFA_004_000_001
CAFD_00000A3F_005_001_013
HWEL_00000A3C_004_000_000
SWFL_000010ED_005_011_000
SWFL_000010EF_005_011_000
I did check blFlash, swDeploy, cdDeploy, ibaDeploy.

But it didnt help at all :/

Can anyone help?
