Moin people, I have several problems with coding the preheater at the 730d Bj 2001 and hope you can help me. You should change the following values in the NCS: IKE: Preheater active IHKA: Additional water pump active Stand-heuzung_Concept sh_high_without_lock valve IKE is displayed in the NCS. I don’t have IHKA. I have IHK, instead of IHKA. What does that mean? In the IKE I have a preheater from non_active, on active. In the IHK I also have additional water pump active. The entry Standheuzung_Concept sh_high_without_lock valve is not available. For this there is the entry Standheuzung_Konzept sh_high_without_lock valve. For this there is again in the IHK the entry Standheuzung not_aktiv. So after I have active stand heating(IKE) and additional water pump active (IHK) coded, is also shown to me Standheizung in the display 16:9. There are: time 1, time 2 and direct operation. If I click on direct operation, the hook goes out immediately again and nothing happens. Then I have set a time and waited. The red lamp f ür SH lights up all the time, as it must be. But when the set time is reached, the red lamp goes off and nothing happens again. No noise comes, just nothing. Can you help me there somehow? Do I still have to put on active in the IHK heater? Or where is the error? fuses from the SH are ok. Tank is half full and the battery is new and charged. Vehicle is an e38 bj 2001 730d 193 hp. Greetings Mark
