Heater, Disassembling And Assembling
WARNING: This page is about a different car, the 2024 Audi A4 allroad. However, it is still accessible from the selected car via links, so may be relevant.
The disassembly and assembly procedures for the heater are identical to the "Low" A/C system heater and A/C unit. Refer to FRONT HEATER AND A/C UNIT .
- The heater on a vehicle without an A/C system is the same as the heater and A/C unit on vehicles with a "Low" A/C system. The evaporator installed in the heater is without function, here it functions only as a place holder and to reduce noise. Refer to the Parts Information.
- The expansion valve -C- is installed on a vehicle without an A/C system only to seal the pass-through in the grommet to the vehicle interior.
- The connections on the expansion valve (for the A/C system refrigerant lines) are connected on vehicles without an A/C system with a closure cap -A- (tightening specification of the nut -B- 8 Nm). Refer to the Parts Information.
