G05 Heated Steering Wheel Retrofit

G05 Heated Steering Wheel Retrofit
Hi All,

Retrofitted a Heated Steering wheel to a 2019 G05 but cannot seem to clear the Armrest errors in the BDC.

Added 4HB to Vo as 248 is not accepted when calculating FA.

Compared all the changes in the BDC & MGU, MGU correctly shows only seats & steering wheel but I have 2 errors left in the BDC for LIN messages missing from armrests.

Has anyone had experience with this?

Any assistance is greatly appreciated

248 isnt available in G05. Try disabling the armrest heating option in BDC using fdl coding.

I did compare all the BDC files before & after & disabled any lines that referred to the Armrests however the 2 errors still exist

RE: G05 Heated Steering Wheel Retrofit
Youd better post errors you had got. At first sight, only one string appear to be in charge of armrest heating:

ARMLEHNENHEIZUNG_FRONT: nicht_aktiv [00]

These are the only differences I could find:

RE: G05 Heated Steering Wheel Retrofit
The solution is there in the difference. You just have to take sometime and disable the relevant fdl lines one by one until you find a combination that works.

Agreed, thats what I did, this is how its configured below:
MGU
HMI_SPEECH > SVS_CONTROL_LENKRADHEIZUNG aktiv (01)
HMI_SPEECH > ARMREST_FRONT_CONTROL nicht_aktiv (00)

BDC
BffEPM > fEPM_Sitzheizung_EV_1 76_Prozent (98)
BffEPM > fEPM_Sitzheizung_EV_2 68_Prozent (88)
BffEPM > fEPM_Sitzheizung_EV_3 72_Prozent (90)
BffEPM > fEPM_Sitzheizung_EV_4 40_Prozent (50)
HcArmrestHeating > ARMLEHNENHEIZUNG_FRONT nicht_aktiv (00)
PfLinLRE > LIN_VARIANTE_LRE lre_tlc_lhz_taster (05)
PfLinLRE > LRE_LHZ_VERBAUT aktiv (01)
PfLinLRE > CODDT_BYTE_00_LRE_LIN LHZ_LRE_mit_TASTER (03)
PfLinHOD > CTRL_HOD_CODG_STWH_LIN verbaut (01)

RE: G05 Heated Steering Wheel Retrofit
Disable these 2 parameters and after coding, be sure to reset the bdc tool32 and you will be happy
BDC: ARMLEHNENHEIZUNG_FRONT
MGU: ARMREST_FRONT_CONTROL
