Citroen C5 X7 additive a FAP

[Maurino]

Bonjour à tous,
Je possède une Citroën C5 X7 avec le numéro de châssis (VIN) VF7**************[VIN obfuscated, can be read by forum staff] et le code ORGA (RPO) 10861, qui correspond à une date de fabrication approximative du 5 mars 2010.
Le problème est que je reçois un message indiquant que le niveau d’additif FAP est très bas.
Je vous serais reconnaissant de bien vouloir me confirmer le type d’additif approprié pour ce modèle.

The problem is that I'm getting a message that the FAP additive level is very low.
I would be grateful if you could confirm the correct type of additive for this model.

Any help, please?

Well you would need to check what color is the cap (click-fit) on FAP fluid (EOLYS) reservoir.

White: EOLYS DPX 42 (Gen 1)
Green: EOLYS 176 (Gen 2)
Blue: EOLYS POWERFLEX (Gen 3)
Black: EOLYS Extend (Gen 4)

what about infineum f7995?

[kantica]

That should be the same thing as EOLYS 176 just from another company / producer, and can be mixed with EOLYS 176.

FROM CHATGPT:

Mixing Eolys 176 (Gen 2) with Infineum F7995 (Gen 3) is strictly not allowed.
They are chemically different and were designed for different DPF systems and injection strategies. Mixing them can lead to:

Additive system malfunctions

Failed DPF regeneration

Clogged particulate filter

Error messages and warning lights on the dashboard

Costly repairs or even full DPF replacement

Official PSA guidelines:
Fluid Type Mix Allowed? Notes
Eolys DPX 42 + 176 Both Gen 1 and 2 – incompatible
Eolys 176 + Infineum F7995 Gen 2 + Gen 3 – must not be mixed
Infineum F7995 + PowerFlex Gen 3 + Gen 4 – also incompatible
Your configuration:
RPO 10861 ? Infineum F7995 only

If your tank has a green connector (typical for Eolys 176), but your ECU is configured for Type C, you must continue using Infineum F7995-compatible fluid.

If you ever suspect that a previous owner or workshop mixed fluids, it is strongly advised to:

Flush the additive tank;

Clean or regenerate the DPF (if possible);

Use Diagbox to reset and reconfigure the additive counter and fluid type.

Oh if chatgpt says so then it must be true LOL
