General Hot start issue 2007 1.2 panda

[Mousendahouse]

My panda from 2007 (1.2 8v) has been having issues starting correctly whenever the engine is at operating temperature. So far it will start but i usually takes two-three tries. I have tried cleaning the battery terminals. Whenever the engine is cold. The engine starts up with no issues at all.
Any reccomendations on how i can fault search this issue?
Thanks in advance, Benjamin

At cold start the ECU bypasses the O2 sensors. This defaults to a rich mixture so the engine starts from cold but is too rich to start properly when hot. The O2 sensors should be switched in when it reaches operating the temperature this corrects the air/fuel mixture.

Potential sources are O2 sensor problem or a temperature sensor problem or even low coolant so the gauge is not covered properly.

Thanks for the reply. I'll go and check how my coolant level is, straightaway.
