BMW F31 seat heating retrofit - Tom329 - 04-06-2016
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

What you use for it ? ISTA ?
RE: BMW F31 seat heating retrofit - Tom329 - 05-06-2016
Esys 3.27.1, dont have ISTA running yet

First program the new airco panel and then coded it.

Do u have any guide? Do i need ISTA P? I thought programing and coding ist the same.

Programming is new Software
Coding are new or more Functions

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

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?
