Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Fluid Reservoir With Dryer
Under certain conditions, fluid reservoir with dryer is no longer to be replaced after each time the refrigerant circuit is opened. Refer to Removal and Installation .
Special tools and workshop equipment required
- Torque wrench V.A.G 1331/ (5 to 50 Nm)
- Robinair A/C Service Unit ROB 134APF withRinsing Device For Refrigerant Circuits VAS6337/1A
- Workshop Crane VAS 6100
- Engine Sling 2024 A
Removing
See notes, refer to REFRIGERANT CIRCUIT COMPONENTS OVERVIEW .
Refrigerant must be extracted before hand using for example, ROB 134APF.
The previously used service stations can still be used. Refer to V.A.G workshop equipment.
To prevent the entry of dampness all components of the refrigerant circuit which have been opened must be sealed with suitable plugs.
-- Extract refrigerant for example, using ROB 134APF, only then open the refrigerant circuit.
-- Move the lock carrier into the service position. Refer to Description and Operation .
-- Remove the radiator mounting bolts (7 Nm) -arrows-.
-- Hang cooler on VAS 6100 and VAS 2024A using workshop equipment (cable ties or welding wire) and unhook cooler from lock carrier, coolant hoses and refrigerant lines remain connected.
-- Unscrew mounting bolt -2- and remove retaining clip.
There is a danger of ice-up.
Refrigerant leaks out if refrigerant circuit is not discharged.
Refrigerant must be extracted before opening the refrigerant circuit. If refrigerant circuit is not opened within 10 minutes of extraction, pressure may form in refrigerant circuit due to evaporation. Extract refrigerant once more.
-- Remove bolts -1- and pull fluid reservoir with dryer upward and out.
Depending on condenser, bolt -1- may also only be installed once.
Installing
Install in reverse order of removal.
First tighten the bolt(s) -1- to 4.2 Nm +/- 0.7 Nm and then mounting bolt -2-.
When installing cooler, ensure that sealing strips are seated correctly on cooler.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
