There might be different connection issues including the non-compatibility of Citroen from 2003 model year with OBD-II standard.
It would be preferred to see the detailed connection protocol for more suggestions.
please do the following steps:
- start car's engine
- unplug/plug back the adapter, check that it's powered
- (for Bluetooth) turn off/on Bluetooth support in you phone (or reload phone)
