Some diesel models of Volkswagen Tuareg 2, which are not equipped with an autonomous heater, have a full-time heater of Eberspacher. It can be determined by means of VagCom (block 18).
The building block is used as an additional heat source for the engine, but it can be reprogrammed into the preheater. To do this, you need to enter a hidden green menu and put the Auxilliary heating check in the Car/Cardeviceslist section. Then, in the Car/Carmenuoperation section, set the Auxiliary heartbeat to 5. Reboot the system by pressing the Phone, Nav, and central spin buttons at the same time. In block 08 -AutoHVAC select Coding-07 and then select Long Coding Helper. In the second byte, we set the 4-bit check mark and save the encoding. Turn off the ignition and get the key for 5 to 10 seconds. It's a car factory again. The "Climate" menu should have a clock icon to display the timing of the warm-up time.
