Is there such a thing?

There's a book By Lindsay Porter (??) which does about 5 others, is that indepth enough though?

Will the Cinq Haynes do for most servicing (fluids, brakes, tappets, cambelts etc)?

what year is your sei, if it upto 2001 then a cinq manual will be fine to use

It's a 2001, but I think it's the MPI version (aren't all Schumachers?), so does that make a difference?
