We are quite lucky with the 306 because we get OBD support. The 206's of the same age don't... they didn't have to until 2004 iirc.
That said, when manufacturers HAD to offer OBD support on diesels from 2004 the support is usually better, so a few more sensors are covered, but still not all of them.
I've not invested any time into it yet, but afaik OBD is just an interface for PID addresses in ECU memory which are listed. In theory you might be able to query any address for any value and watch it... but it's finding the addresses hehe. I need to look into it more but it *might* be that you could check stuff like rail pressure etc via OBD.
Not sure about the Peugeot Planet values like IQ etc... they might be calculated in software, then again they might be internal values you could log... just need to test but it's finding the time.
Would be nice to be able to just log via generic OBD some of these values as PP is slow and painful to use sometimes.
