Hi ROBINHOOD,
Which program do you use to activate quick heat?

 

Any proper guide or how to with complete wiring instructions in the meantime? Looking to add it to my diesel, first winter with a diesel and the slow warm up is annoying already

 

It is very easy to retrofit. You pull the plus cable into the engine compartment to the fuses and take the minus cable directly from the carrier on the center console. The control goes to the climate control unit (you can see in the pictures). If you have any questions, just write to me and I will describe it in more detail. Finally, Robin has to change the software in the climate control unit. It's great and I can only recommend it.
