Which A/C gas?

Unread post by Apurpleproblem »

My DS 3 Hatchback(facelift), 2016 1.6 HDi, it’s going in on Saturday for its A/C Regas, it either has R134a or R1234yf, which one?

Have a look under the bonnet, there might be a label with the gas type and quantity, possibly on the front panel but could be elsewhere.

Our 2015 308 uses R1234yf so I would think yours would too. I believe that the connectors are different to prevent accidental filling up with the wrong gas.
