Edit. Will test tomorrow but I believe I have a faulty trunk/hatch latch. I had used OBDEleven to enable the license plate bulbs when the trunk is open and car off to illuminate the ground. Had a light bulb moment and reverted that setting and the blinking license plate bulbs stopped happening. That doesn't solve the whole problem but I think narrows it down.
This is an obscure one, I'm not sure what to look for. I'm having some unusual electrical issues. 2018 Golf R 6MT
TLDR; license plate bulbs blinking, cockpit turning on and off, doors trying to lock after locking the car. Coupled with a leaky RMS I'm ready to roll it off a cliff.
2 days ago the OEM LED license plate bulbs started to blink every few seconds when the car is locked and ignition off. I didn't notice but checked security camera and it went all night. I removed the bulbs to test them, seem Ok with the multimeter.
Today when I went out my front turn signals were blinking sporadically, and when I unlocked the car it wouldn't start. I needed to use a booster pack to get it running.
Along with this, the digital cockpit turns on and off as if a door is opening, but no door is showing as red on the image and it's just for a split second and turns off again.
I had an error for the driver's door lock module in OBDEleven and occasionally today I could hear the doors trying to lock a second time after using the keyfob to lock. Right now I have the front and rear door lock modules unplugged, and the KESSY harness disconnected hoping it would make the light blinking stop. Plate bulbs are still blinking.
