I looked out in our driveway late last night to see an occasional flashing of my Q7's headlights - about once every minute.
The only strange thing that happened previously was my daughter spilt some water in the rear footwell area which mostly went on the rubber mat. I vacuumed the carpet dry and some went on the rear climate control panel so I vacuumed that as well.
I went out to the car and opened the drivers door and the interior lights came on but very dimly.
I guess the battery died, un-related to the water incident.

This morning, all electrics were dead. I fitted a spare battery I had for my A8 and all seems fine except I am getting no TIP control of the trans and just an ! in a circle in the display on the dash, TPMS warning, no Side Assist and the steering feels heavy at low speed.

I am planning to clear any codes tonight and hope for the best.....

Let us know what happens, maybe the water got to the battery compartment in front while the vehicle was moving, just a suggestion.

I thought everything was OK. When I drove home from work all seemed Ok again, transmission, steering, dash, side-assist - all working normally.
This evening, same again, lights flashing and then the alarm going of again with the indicators flashing until the battery died.
I am charging the original battery now and may just try that and clear any codes tomorrow morning.
I guess I am looking at a battery draining issues - hopefully it's not the dreaded water in the amplifier problem. I had a quick look and it's all dry around the spare wheel.
