Notes on general repairs
The refrigerant circuit of the air-conditioning is only to be emptied and opened if this is necessary due to safety measures or if components of the refrigerant circuit have to be replaced.
The air-conditioning refrigerant circuit also remains closed during all other standard vehicle repair work.
Contact corrosion!
For this reason, the manufacturer only fits connecting elements with a special surface coating.
Contact corrosion can occur if unsuitable connecting elements (screws, nuts, washers, rivets, plugs, adhesives, etc.) are used.
Only use original Porsche parts!
