- 🚗 Original VAG number for VIN-code selection.
- 🌿 Coal filling for protection from exhaust gases.
- 📏 Accurate correspondence of geometric dimensions of the seat.
⚠️ Warning: When buying, be sure to check the integrity of the package and the absence of deformations of the frame, as the damaged element will not ensure tightness.
Tools and training required
The replacement procedure does not require complex equipment or special skills. The main task is to provide access to the evaporator unit, which in the model Polo It's under the glove compartment.

After installation, close the compartment cover and fix it with latches or a screw. Make sure the lid is tight and has no backlashes. The air must not pass the filter, otherwise the whole procedure will lose its meaning.
Assembly and performance check
The final step is to install the site. glove-box. Raise it to the top position and snap the limiters or screw the fasteners. Check whether the door of the cloth compartment opens and closes freely, whether it touches new elements.
Turn on the ventilation system and check the work at different speeds. The absence of whistles, hums or foreign smells indicates the correct installation. If there is a whistle, perhaps the filter cover is not closed to the end or there is leakiness.
