Re: Renault Clio 2003 - Engines - Loss of power and Warning Light
The lambda or HEGO sensor doesn't require the battery to be disconnected. as it is only live whilst the engine is running. It would flatten the battery in no time at all, if it were a constant drain.
Think of changing a bulb - you wouldn't disconnect the battery for that, would you?
Many problems with renaults arise through batteries being disconnected, I'm not for one moment saying it shouldn't be done when necessary, but it isn't in this case.
This job should never be complete - the day I think I've done it all, is the day I resign.
Currently in VelSatisfied's garage:
