What's the 01117 fault code vw?

01117 fault code for Your Volkswagen will generally indicate an overcharging issue with the alternator of Your vehicle. Alternators that have been overcharged will usually produce excess voltage in the battery which can swell up the battery. This is preceded by the battery becoming extremely hot which makes it lose its electrolytes when it reaches its boiling point. Although, this may be an issue, jump-starting the car could send huge surge through the battery that can destroy one or more cells of the battery causing it to short out. Overcharging Your alternator actually produces excess amounts of hydrogen gas, and if the battery isnt properly vented, then the batterys casing can become warped which will eventually result in shorting it out.
