Citroen VTS 1.9 TD Workshop Manual

Hello good, I'm new here and I'm looking for the Citroen Xsara 1.9 TD VTS workshop manual.
I have problems with oil and dirt in air admission pipes, turbo and EGR.
I am disassembling the collector and I would like to look how to disassemble it if with the exhaust collector, if the EGR must be removed so that the collector comes out ... Sim more thanks to which I can guide me
