** Need some Help ** Locating the Air Conditioning Re-Gas Inlet

[so315hy]

Hello and Good Afternoon, I am trying to top up my Air Conditioning with a Re-Gas but I cannot locate where the inlet is, I have tried Google and YouTube but only find other Citroen Model Makes and not the Citroen DS3 2010. If anyone can help me with where it is and ideally a picture of it that would be great, Car is the DS3 2010 1.6 THP155 Model. Thanks Eveyone
