P1352 fault code

Unread post by Andypandy1 »

Hi everyone
I have a citroen c4 1.6 hdi vtr 2013
I've had the dredded p1352 code persitanly intermittent after clearing with scan tool, have changed out relay , code back,
Now I believe that it may be due to bad earth mm01
But how do I access this , how do I remove the filter box seems tight.
I've recently replaced the seals in the brake vaccum , which seems to be close to this mm01 earth point , I may have disturbed somthing in that area .....
I am eager to track down this fault , but as I said access is limited with out tge removal if air box
Any help would be appreciated.....
Also any truth in , if the the glow plug relay system if not functioning correctly , Regensburg will be affected???

I used to be indecisive, now I'm not so sure!
I used to ride on two wheels, but now I need all four!

Hi Yes I have, and the video too, my problem is actually access, removing the the airbox seems a tight mission,on the c4 vtr, so I can get too the mm01 earth point and inspect the wiring to the glow plugs too....can only find peugeot cars , citroen seems tighter to remove the box,.

UPDATE
solved
Definatly was the glow plug earth which was not bolted down.......
No faults since putting bot back in.....bit of a mission but worth it.....followed the youtube videos.
