Peugeot 307 year 2003 error code 63

[colouny]

Hi,
Got Peugeot 307 '03 for some repairs today. The dash was like a christmas tree, i think only some of the warning lights were not lit. I have never seen the car with so "Bright&Colorfull Dash".
Anyway, the only thing i could not repair is that light wich indicated angine overheating while the engine temp gauge is at normal operating temp.
Also the colant level sensor was disconected/broken replaced the sensor with a new one, but still get the "top up coolant level" message at the center screen.

I think in the BSI unit i got the error code 63 with "Autoboss" scanner. It said smth, what i cannot remember at the momet, but had wrote it down.

If anyone could give a hint where i could find error codes, how to translate to PXXXX error codes. It would be nice to have this kind of info on the hand.
Thanks

Made a mistake, The lights are lit on the dash : 1-STOP and 2-"Top UP Coolant"
