Get on the 206 / Pug forums. I'd imagine they have a fairly dedicated if "yoof" following. Normally owner's clubs / forums have a fair few people who have the factory online manuals, which detail what has to be done when. Peugeot have A & B services if I remember correctly, then a few special ones on long intervals for glow plugs etc. It's printed in the front of manual.
Anyhow, the normal service tends to consist of oil, filter, possibly air filter & cabin filter (generally on a B or 2 service), diagnostic check, underbody corrosion material check, brake friction material and check the door check straps / grease the hinges. Gearbox oil is normally on a hugely long interval, if at all – 80K plus.
The owner's clubs also usually know how to reset service lamps and do diagnostics checks for cheap – I have a cable to diag the VWs off ebay, and there's a procedure for the service lamp – usually a dance with the ignition key & the trip reset button.
