Hello members,

I want to ask you about DTC, which i identify on my C5X7 Tourer 2.0HDI 140 FAP.
Today afternoon when i check the system with LEXIA, i find the code P1351, with code description "pre-post heating relay".
(you can see on attached print screen).
what is your proposal for the check? It is real dtc or fantom?
This relay is for glow-plug? All fuses are okay,earth/ground wires also ok.
The DTC light is off, and i can start the engine without any problem.

My other question is regarding "Controlled air inlet module".

During "mesures parametres standard.s : 1257_01" i find the message
"Piloted air inlet module jammed open"(attached print screen 2) and in last row stay for Piloted air inlet module movement,"No movement"
Where can i find this "Piloted air inlet module"?

Thank you for your helping.

P1351 "pre-post heating relay". is a known phantom code - I have this on my X7 and had it confirmed by Citroen UK via the dealer.

Maverick,
thank you for helping, by me the problem is no phantom code.I checked the glow plugs one by one. Take out the BSM unit, and below the BSM is located the heating relay unit,if you remove the relay connector, you can measure and check the glow plugs separately.in my case the third glow plug was bad (pink wire).
After replacing the glow plug, clearing the dtc, the problem is solved.
Best regards,
