On a vehicle without an A/C system (only with a heater) the evaporator installed in the heater does not function, it is only works a place holder and to reduce noise. If there are odors in the evaporator, it can be cleaned in the same way as an A/C system.
- Note the cleaning solution product data sheet
- It is recommended to have several short and long spray lances, since they are used either in their straight form, or must be bent to different degrees for various vehicles (or they are already bent). Repeatedly changing the form of the spray lance will damage it and is therefore not advisable.
The recommended bend radius of the Suction Feed Spray Gun - Probe for Evaporator (Straight) VAG 1538/5 (short) or Suction Feed Spray Gun - Probe for Evaporator Cleaning, Curved VAG 1538/6 (middle length) -A- for this vehicle is shown.
TIP
The guide washer -B- is attached opposite of the spray lance holes -C-. This also allows the spray direction to be detected when the spray lance is inserted.
