Do we have the 2012 service manual for the Citroen C4 or does this 2004 cover it all? Reading it seems like it covers everything i need, but im having a hard time with such an old manual, and i feel i might be missing some information about the clutch specially, like, what is the name of this part? The Manual doesnt cover it.

The name of the clutch part for the 2004 Citroen C4 is not specified in the provided context.

The 2004 service manual covers specifications, adjustments, checks, and special features for that model year only. It does not include information for later years like 2012. Therefore, it may not cover all necessary information compared to the 2012 version.
