Hello all together, has one of you ever replaced the additional heating in a Euroliner (current series), the additional heating is in the rear, with a Eberspächer air heater Airtronic D4 (Standheizung)? In the option list also a Eberspächer air heater is provided for the additional heating. My Ford dealer he used about 6h for it => 400€ for the assembly. I would like to save the money and install it myself. But otherwise there is no room in the bussle for a s Is the additional heating, do I have to throw out the additional heating?
