Pat oil tank.

[Onion_Bhaji]

Another member has raised an issue on another group about a pat oil tank on B9's that need filled up at 100,000 miles.
I've asked the question on that group but haven't received an answer.
Does all citroen berlingo B9's have one of these pat/oil tanks.?

maybe it's the Eolys fluid, I don't know about the pat oil tank, but that Eolys fluid needs to be refilled at about 100k miles.

Does all B9's have this then.?

After 2010, yes. All B9 have the PAT fluid. It's not oil and it's not the same as Adblue. They do different jobs and all B9 from 2015/16 will have both systems. PAT fluid is a cerium oxide solution which helps the DPF cleaning at a lower temperature, and Adblue is injected into the cat as an SCR treatment to reduce NOx emissions.
