Blinking tail lights and license plate lights

[Chris Black]

I'm beginning to wonder if facelifting my Q7 was such a good idea after all.

I purchased OEM facelift taillights and installed them, with no problem. I already had changed the stock halogen headlights to HIDs. The front turn signals were also replaced with OEM led turn signals.

The final part, which has now seemingly caused the malfunction, was changing the halogen license plate lights to HIDs.



Now here's the problem: I found out after about 4 minutes of idling (and I'm assuming the same happens while driving at night), the rear taillights, as well as the rear license plate lights flicker about 3-4 times, then shut off. What's stranger even are my headlights and front turn signals are unaffected. So the rear shuts off, while the front is fine.


I've noticed the battery (which I replaced not but 6 months ago) runs perpetually low. When I go to battery monitoring on the MMI, it always has me at 10%.




So what the heck is going on? Did switching everything from factory halogens and the first gen tailights to all HID/LED/facelift equipment overload the battery? I can't figure out what the hell is going on. I'm thinking about ripping the gate off the trunk and checking the wiring to the taillights and license plate lights. What's the problem?

Have you tried LED license plate lights? I have those but for the 2012, swapped the halogens BUT mine are flickering now ahaha and dying :(
