There are 3 possibilities: either the battery is going bad, a device is being left on in the car (lights, etc) or an alternator diode is shorted.
Hi I am having exactly the same problem - except that I have not changed the battery recently. This is a very common fault in Renault megane II of this age as is inherent problems with the turbo giving out. if you google Renault megane steering fault you will find many people with the same problems - also visit www.meganeownersclub.co.uk for some more support
the most likely reason is that the gas pressure is too low.Get the gas topped up at an AC specialist.
For whatever reason this question seems to attract spammers and nonsense answers. Ask the question again with the year listed.
Have you tried topping up the hydraulic fluid tank for the electric roof, which is located in the boot on the left hand side under the felt? Fluid for this can be bought from Halfords for about £15 a litre.
Unnoticed accessory left on? i.e. trunk light, glove box light Excessive parasytic load? Bad voltage regulator - not opening circuit on shut-down?
Stationary Cycles are a popular exercise tool and they are for good reason. They can be found in many places online like the official Sears and Walmart websites.
The most common reason is one of the cells in the battery is bad and the only thing to do is get a new battery
The battery has a temperature sensor. If it was left unplugged, the battery light will still be on
an awful lot of Renault drivers suffer poor starting and a simple replacement of TDC or flywheel sensor solves it - might be carbon related - costs fifty quid or so plus a little labour in most places and main dealers don't seem to know about this common problem The reason is because the steel tip of the TDC sensor which picks up a signal from the flywheel telling the ECU when to fire the spark plugs gets dirty after a year or two and cannot get the signal. There is no need to pay up to ££90 for a new one at a Renault garage just simply remove it and clean the tip! also clean the connector.
The main reason for the battery being in the trunk is to save the life of the battery. GM has improved the life of a battery to 5-plus years.
Either something is on and is drawing current from the battery or the battery itself has a dead cell which will drain the battery. If the battery is over 3 yeas old, replace it.
make sure all the doors are shut and then trey again.
