Doorbell (AVD4001) won't successfully update its firmware (currently 10.0.2509_f51e5dc).

It either fails or tries to update for over an hour.

How do I get it to successfully update?

Things that that I have tried but didn't resolve the issue:

1. A restart of the doorbell.

2. Removing the doorbell and re-adding it to the basestation.

3. Removing the doorbell and re-adding to wifi.

4. Reset Doorbell to factory setting.

My Audi A4 b6 sucks about a 1/2 liter of coolant into engine while driving, after returning from my drive. I see that the reservoir is about 1/2 liter low, so I let the engine cools off.

I remove the coolant reservoir cap and to my surprise the 1/2 liter of coolant flows back up into the reservoir. WTF??

Brand new reservoir and cap, and it has been bleed a couple times. No leaks (including the coolant flange). So, all of the low hanging fruit has been vetted.

I love the design of the new ADT Base (ADTBASE502R0). Physical buttons always are superior to touch screen buttons.

I've only had to call them once and that was for something simple. Knock-on-wood.

Losing coolant without any visible leaks. Trying to troubleshoot it. No leak puddles on the ground.

Should I start out with replace the reservoir tank cap? Maybe it is worn and would it vent? like a radiator cap?

Even those these Audis don't have a radiator cap.
