Citroen C5 X7 2,2 HDI cone filter

Unread post by VeloDK »

hi guys i recenty fitted a cone filter to my C5 and i was wondering if anybody knows if you could take the mass air flow sensor from a 2,7 HDI or 3,0 HDI so that it stops creating fault codes?
if it helps it keeps throwing the code P0100 :-D

We cannot comment on that type of modification as it takes the vehicle out of spec. However this link to the full description of that generic fault code might help you in working it out. viewtopic.php?p=811473#p811473

Is this fault code on happened as soon as you changed the air filter?

If it clears when you put the original air filter back then the cone filter may be the culprit, possibly it is letting too much air through. You could also check the MAF wiring has not been damaged.
