I'm betting on almost 100% to the purge valve, which is located below the airbox housing. To reach it, need to remove the full housing.
Hi. How are things going with the car? I've already done something. I'm sick and I can't work on the car yet.

Hello, having the exact same problem with a DS7 Crossback 1.6 petrol 225, who can I even find or go to, to be able to go through with a diagnostic tool and fix it? It’s been to 3 separate people and they haven’t a clue. I’m so lost on what to do!

I solved the problem. Purge valve was a problem. He was letting the air go throught.

did you replace it or repair it? did you think about disabling it programmatically? maybe there is a part number?

Many thanks to @MiroMirchev for the link to the Dutch site. I have been puzzling over the P306D DTC for a while. Like others, I couldn't find a part number for the solenoid valve anywhere, so I had to find the valve first.
In my 2019 508SW GT 225, it lives beneath the air filter box at the rear of the engine, it pokes out slighly from under the inlet manifold (gearbox side).
Part number V759557380
I fitted a salvage part from an RCZ, straight away I could tell it was running better. Originally the check engine light started coming on every 5 weeks or so, that went down to 1 or 2 days in the end. Although it's only been a few days since fitting it, I'm quietly confident it has fixed the problem.
Hope this helps others.
