Narrative:
During flight descent we noticed the engines mismatched in idle on the arrival. There were no ECAM or status messages that drew our attention to the problem. After analyzing the problem; we suspected an issue with the left engine or the left engine fadec; although there was no indication on the ECAM or status pages. We ran both engine anti-ice; temporarily; to see if that would clear the problem even though we were not in icing conditions. The engines responded normally to throttle advances and matched up as long as they were not in idle. We discussed the situation and decided not to shut down the engine at that time. The captain [advised] approach. I flew a normal ILS approach to an uneventful landing. The flight attendants and passengers were briefed on the [situation]. After engine shutdown at the gate the ECAM showed maintenance status message fadec 1. After consultation; maintenance said he had a discrepancy message left engine fuel temp sensor. Discrepancy entered in the logbook.
