@@CoolAirVw I found a capacitor that was leaking in my monsoon amplifier. The amplifier is connected strait to the battery A+12v positive. and ground the key switch B+ and fuses aren't connected to the amp. 3 days and dead battery. The amp gets power from one of the big fuses on the battery box. The radio gets voltage from the amplifier in the trunk and the capacitors are parallel to the battery voltage. It seems like I got the idea to put a 12v relay from the key b+ at the fuse box to the switch on battery voltage and amp from someone on youtube but I can't find the link. Who showed us this monsoon amp problem and how to hook up a relay? I thought it was Thomas EXOVCDS. I watch his videos all the time but I can't find the monsoon amp relay video. this is a common battery drain and also installing the aftermarket radios like you are diagnosIng.
I have the same problem my daughter left the headlights on an the battery was dead I bought another battery two days later it was dead. I was wondering could it be that the headlight wires burn into or something touching an making it go dead?
i have a 2013 vw cc. one afternoon before work i had to jump my car to get to work, i figured my battery was bad,bought a new one. next day same thing battery was dead, got a jump and went to work. went to oriely's to have them check the battery and alternator theyre tester said i needed a new alternator so i got that changed. still battery dead. the only thing that keeps me from having to get a jump to start my car is if i dont lock the door because there is a red light that flashes while the car is locked. if you have any ideas what the problem is please let me know, could that be a fuse or bad wire?
drain problems are some of the hardest problems to diagnose as it could literally be anything on the car. Seek someone good to do a diagnostic process like what was in this video or the other one that I did which I believe is linked in the cards.
@@CoolAirVw thanx for the reply i got the person that changed my alternator basically doing the same type of test you were doing with the fuses and relays ill let you know what he finds and if it fixes it
I’m having trouble with the same problems with draining the battery but my satellite quit working not the radio. VCDS gives me radio/satellite code. How do I fix?
Did you fix it? I am having a parasitic problem on a 2004 VW sports wagon TDI. I think there is a short in flasher warning and turn signals as they went out for a few days and I had no problem. Then they started working again and not my battery is going dead. Is this possible?
my problem was both the radio and amplifier under drivers seat unplugged radio still had drain pulled 40amp fuse under hood for amplifier had a 1.5mamp draw fixed the problem or you could unhook the amp under drivers side set
I have a similar problem where my battery drains everyday! i have an after market radio, might be the issue, also when its dead my 449 relay clicks constantly! which makes me think it might be apart of the issue, trying to diagnose it as i type
Well I've tried everything with this vw jetta a 2015 battery and alternator change and it worked fine for a couple of months and now it's starting to die out on me again jump starts perfectly fine but as soon we turn it off it dies
I have a 2009 cc (same car) with the same issue. The mechanic however couldn’t locate the source. He attempted changing the pesky door modules, changed the battery, confirmed the alternator was good. He’s giving up and asked me to pick up the vehicle. NOTE: their is another fuse box left of the steering wheel. I wonder now if it’s the radio, seems to be a common issue. I also just learned that prior to the battery draining/dying, the horn stopped working. Any advice is welcome.
@@CoolAirVw you saved ne a lot of money. I was having the same problem. I removed the radio and problem solved. I was ready to have it towed to the shop to get it fixed and totally stressed about how much it would cost.
It literally could be any device on the car. The video shows the diagnostic method for you to figure it out. My other battery drain video shows some more.
@@millerterrence82 this video and the other video I have on battery drain should help. The other video is on a similar car to yours and in that video I mention every battery drain problem I've ever fixed on a Vw.
Hello. I have a 2011 vw Jetta and the radio does not turn on.The battery light is on, I replaced the battery and alternator and the battery light still on. Is funny how my Bluetooth still connect to the car but the radio does not work, no lights or audio. HELP
@@CoolAirVw So I haven’t fix it yet. So if I disconnect the radio from the car it doesn’t drain my battery but if I keep the radio connected to the car then it drains my battery. Is the oem radio and it doesn’t work
@@jorgemedinaregalado490 yes. I got a new radio from cruthfield. They sent me a radio that fit perfectly on the dash and all I had to do was just plug it in. The vw Bluetooth is under the drivers seat so I unplugged it in order to make my aftermarket radio work. Is really simple. I paid 200 dollars all together. 2011 vw jetta. You call them and give them all the information of your car and they will take care of it
@@jorgemedinaregalado490 The battery light was the accessories computer. I bought one for 50 dollars and had a mechanic install it for me. I paid 150 for the install.
I have 2010 sportwagen and had random battery drain unable to traced problem until one night and found the radio buttons back light on bingo its the FN radio.
Just contributed 20 to kansas City TDI. Thanks for the video Richard.
thanks!
Thank you for this impressive tutorial on parasitic draw diagnosis.
awe shucks! your welcome.
You fixed it all right that's all that matters. Good job
thanks!
Current draws can be a real pain... we had one (a couple years ago) with similar radio and similar problem.... was a white Jetta though. =)
Luckily those problems don't come through my shop much.

@@collinhales3551 My other parasitic drain video the problem was the amplifier.

I have no idea.
Those current draws can a real problem to find, had one in my Volvo wagon and it was the glove box bulb not shutting off.
part of my process is to always check the trunk light and glovebox light. I think I showed that in my other "draw" video.
Very good research of an issue. Thanks a lot. A réal lesson.
Glad it was helpful!

I'm hoping this could be the root of my problem. I've tested everything twice over except the radio without finding the issue. Fingers crossed
Be sure to watch my other battery drain video.
One thing I’m going to do is amp clamp through 10 turns of jumper wire on the positive since that will enhance the accuracy of my measurements.
good tip.
I’m trying to figure mine out 2013 Sportwagen TDI. Will post the issue here when I solve it.
that would be great.

Drain problems are some of the most difficult problems to diagnose.
Having the battery light on and aftermarket stereo doesn’t turn off with the car just replace the alternator and battery what can it be?
Year make model engine?
