Talking Possible Battery Issue? **RESOLVED**

2012 GL350

I'm hoping I have a battery issue.

Getting many warnings(traction control inoperable, cruise control inoperable, SRS issue front right, etc) but the one that has my heart rate up is drive to workshop without shifting gears. - The car has been working great, however it did die for some random reason last weekend - I may have left the car on accessory as I jumped in the roll up the windows prior to the battery dieing. We charged the battery and everything worked fine Saturday/Sunday/Monday/Tuesday. On Tuesday(yesterday) I even got both front wheel bearings replaced and really enjoyed the drive home without the humming noise, was excited to take the kids the daycare this AM and enjoy the silence and then this all happened and my day is ruined.

My closest Merc dealer is 100km away, I also have 1 2 bad rear blind spot sensors, so I'll pull the bumper and remove those shortly.

Anyone have any recommendations?

Here is the export of the ODB2 reading: https://pastebin.com/raw/JBByMrdD

BONUS: Here's as photo of my towing my trailer with it, it's honestly such a nice tow vehicle it makes towing enjoyable.

UPDATE - RESOLVED

Problem:
2 bad blind spot sensors in rear bumper.

Solution: Removed rear bumper, removed sensors, taped off sensor plugs really well and reinstalled bumper.


I removed the 2 bad blind spot sensors and they were much worse than I thought. The 5A fuse has been pulled for like 2 months so I figured it wouldn't impact anything as no power was going to them & I'd just pull the bumper off when I ended up ordering the new sensors. This fuse kept on blowing & also provides power to the wipers so I've had no wipers for a few months -- but I've discovered Rain-X works amazingly well. Hopefully this helps someone in the future that's about to have a coronary like I was this AM.

All is good with my GL350 again. Took it for a drive on the highway and worked like a top & the wheel bearing noise is gone. Very Happy

I tore apart the 2 sensors, here's a photo - they've seen better days!

Not sure, was going to check but It may be factory from 2012. Since removing those sensors, I've had no issues at all so I haven't gotten around to checking the battery date.
