Are you tired of always seeing the battery warning light illuminate in your Volkswagen? Do you want to end the frequent need to jumpstart your car? A car battery is expected to have enough power to start and keep your car going on the road. Still, if your Volkswagen has repeated battery issues that make it break down and fail to start when you need your vehicle the most, there is a problem somewhere.
Battery drain is annoying, especially when you are in a hurry or parked in an ill-chosen place. It is even worse when you replace the battery, and the problem repeats after some time. This article explains what causes battery drains and how you can solve them so your Volkswagen vehicle will serve you well.
What Causes Volkswagen Battery Drain?
There are several causes of battery drain in your Volkswagen. The first battery issue is a parasitic drain. A parasitic drain is a situation where electrical accessories in the car, such as a defective sensor, interior light, or radio, continue to draw power even when the car is turned off. Battery problems can also mimic a drain if your battery is old, weak, or more than three to five years old. A bad alternator may not be able to charge the battery adequately, which results in frequent power loss. Also, corrosion or loose connections can cause your battery to drain as if it is being used. Lastly, extreme conditions, such as cold, slow down the chemical reactions, while heat affects the battery through the evaporation of the fluids.
How to Fix Volkswagen Battery Drain Issues
- Check and Replace the Battery: The first step to rectifying battery drain is checking the battery’s health condition. A weak or old battery will not retain charge well; therefore, using a voltmeter or taking the battery to an auto shop is necessary to see if it needs a replacement.
- Look for Parasitic Drain: Ensure that the headlights, interior light, and other electrical devices are switched off before you leave your Volkswagen parked. Some cars have automatic shut-off systems; however, it is always advisable to manually check to avoid unnecessary battery drain. A mechanic can conduct a parasitic draw test to determine if an electrical component is pulling current while the car is off. This involves determining the amount of power the battery consumes when the car is not in use and identifying circuits that drain power.
- Check the Alternator and Charging System: A bad alternator may hinder the battery’s charging process. If your battery is dead and you replace it, but it continues to drain, it is advisable to check the alternator to determine if it is functioning properly.
- Clean and Secure Battery Connections: Rusty or loose battery connections can disrupt charging. Regularly cleaning terminals and checking the tightness of the connections may help improve battery efficiency and avoid power loss.
- Take Longer Trips to Charge the Battery: Many VW drivers are fond of driving only short trips within the city; if you’re one of them, then you may want to consider occasional long trips. Going for a longer trip with your Volkswagen charges the battery and keeps it healthy.
