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:

found this info on a European car website

Cost me £40 (mates rates, this will be more if done via the proper procedure) and we were told it was the fuel system electronics holding impact data which needed clearing.
The dealer confirmed the clearing of the airbag ecu was successful and correct however the fuel cut off was retaining the airbag lights presence and not allowing the car to run.

So, if you're reading this in future and your car will not run after an accident and you have had your airbag ecu reset and airbags fitted etc, it is probably your fuel system electronics holding the data still and you should probably try and find someone with the computer capability to change the "impact data" field in the electrics from yes to no.

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.
