Glow plug Citroen HDI

[mar666]

Hi,
Citroen Xsara Picasso 1.6HDI and 2.0HDI.

1.6 has separate 4 lines from relay to glow plugs. 2.0 hdi has 1 common line from relay to plugs.

What voltage (12V or 5V) is used to power the plugs in both models ? I've seen in 2.0 5V on plugs and I'm not sure is it correct ?

how does the "diagnose line" in relay work ? Is it only logical state that means "glow plugs are ok" ?

Does 1.6 good working relay "clicks" when tested from Lexia ? I can't hear anything. In 2.0 it is clear sound of relay.

Thanks !

Should be 12V in both models mate.
