tiguan battery keeps draining

Asked by GuruCQJNS Feb 26, 2019 at 10:04 PM about the 2013 Volkswagen Tiguan

Question type: Maintenance & Repair

Car is only 5 years old but after complaining to the Dealer, they opted to
change the battery. No difference. If the vehicle is not used at least once every
3 days, when I go to start it, the battery is dead. Something is draining the
battery. Volkswagen mechanics say the car is fine but I don't think they can find
the problem. Does anyone else have this issue?

Did they look for a parasitic battery drain or just blow you off? A better battery could reduce the issue but not cure it.

My Tiguan is doing EXACTLY the same thing. VW also say its fine and cant find anything. If you find out what is doing it PLEASE post it here. They put in a new battery but it still goes flat.

I have had this issue over and over again. I bought the pre-certified and they charge or change the battery and blow me off or blame me for leaving something on. Its so fustrating. Its been in the shop 8 times since I bought it. Im a woman so they blow me off over and offer again. Made me cry several times. The car has left me stranded and Ive lost days of work and on my own late at nght stuck somewehere

the indicator left down/up leaves a park light on - make sure you turn the indicator off as it will drain the battery. there should be a warning ding ding ding but if you miss or in a hurry it will keep the light on even if you lock the car and walk away.

This is happening to me as well, and I too am a woman, and I get the same blow off response. I bought mine brand-new, and I am getting really tired of going into the shop for this. I never leave anything on, I ensure that there are no cords plugged into the console when I get out, and my battery that is 3 months old just went out. I am thinking this is not a battery problem, but I can't get the dealer to listen.

I've come to the conclusion that when it comes to a VW Tiguan, the Electronics are advanced to the degree that you MUST drive the vehicle AT LEAST once a week and for a half an hour or more, at 2500 RPM or higher. The only way I could beat this problem when leaving the vehicle for extended periods, was to disconnect the Negative Terminal on the Battery, and then it was fine to start even months later. The newer vehicles with Anti-Theft, Computer, Memory in the Radio, and other Electronics, are just too much of a drain on the battery. Don't let this happen too often or the constant Drain/Recharge on the battery will damage it to the point of needing to replace it and VW Batteries aren't cheap!

I have same problem. Tiguan DSG with house anti- theft fitted, 2017. Battery hoe6d down after few days inactivity. Had battery replaced twice once from WV once from the Leaseplan auhorised dealer (it is leased car so cannot take directly to WV). They did diagnosis, did not find anything and replaced battery, but same happens. However I could nit get them to measure the charge current or standby drain current.

We've installed a trickle charger on my 2013 Tiguan. I just plug it in every couple days

Yes Trickle Chargers do help but in our case the Tiguan is an underground Condo Garage where there are no Electrical Outlets for each vehicle. So in our case, if it's left for any significant time frame, the Positive Terminal of the battery MUST be disconnected, otherwise after about 6 weeks, the Battery is dead. It was our only option.

2016 Tiguan on my 4th battery. That’s ridiculous!
