Special tools and workshop equipment required
- Suction Feed Spray Gun :VAG1538 (Refer to Parts Information for currently available suction feed spray guns)
- Suction Feed Spray Gun - Probe for Evaporator (Straight) :VAG1538/5 -A- (short version approximately 500 mm, bent to specification for this vehicle, or Suction Feed Spray Gun - Probe :VAS1538/9 ). For probes that can be delivered currently, refer to the Parts Information
- Cleaning Solution for A/C System Evaporator "D 600 100 A2" (for cleaning fluids that can currently be delivered, refer to the Parts Information)
- Suction Nozzle With Brush :VAS6288
- Commercially Available Vacuum Cleaner
A/C unit may be contaminated by other substances

The vacuum cleaner is only necessary if there is dirt in the plenum chamber or in the A/C intake shroud, or if dirt has gotten into the evaporator housing through the dust and pollen filter.
The Suction Nozzle With Brush :VAS6288 is only necessary if dirt has gotten into the evaporator housing through the dust and pollen filter.
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.
