Disconnecting battery overnight?

Will disconnecting the battery and leaving it disconnected overnight reset the ECU?

I don't think it will.
I know it's not the same, but I tried to reset the ecu in my car by disconnecring the battery.
Even after leaving the battery off for like 2 months, whilst I was on holiday it still had not reset.


Anyone know how to reset a Renault Megane..:haha:

Thanks for that info.
Actually meant it as a joke.
My Megane is way past worrying about a reset.
It caught fire last year, when the alternator ate the fule line.
