Got lights on for engine management and antipollution air filter. Car des not seemed stressed in any way car runs very well just done 200Miles plus on motor way with additive lights still on but nothing going wrong, no loss of power, no juddering nothing. Can this just be faulty lights.

hmm,
additive light,
so Peug/Cit or one of the other makes that use the PSA engine.
that system is to help the DPF stay clean,
ignore it and say goodbye to the DPF,or if it's the PSA1.4 or 1.6 it'll kill the engine too!
DPF filter soot,
same stuff you got up chimneys long ago,
the additive burns at a higher temperature so as to clean the filter,
No fluid means it will choke up.
