2011 A8L - Been meaning to ask this for some time, now. Every time I wash my car, the doors lock/unlock over and over, whenever water gets on/in the door handles (all 4 doors, by the way). Obviously, water is getting inside and 'completing the circuit' for the lock buttons.

Questions:
Does anyone else experience this?
Is this a common fault?
Is it something I should take care of? How? Is doing so a big pain in the ****?

I hope to keep this car for a good, long time and I want to take care of it. If possible, I'll be doing the work myself. I do everything I'm able to do, if it saves me $180-an-hour in shop fees! I also have a VCDS, if that's needed.

Thanks, y'all!

Same thing here, I leave the key inside the car now when I was and it stopped this from happening, but yes very annoying. I know not much help but you’re not alone and I’m guessing it’s a common “fault”.

Yes, common issue. Same on our 2013 Q5. I don't think the water is getting "in" anywhere--it is just triggering the switching due to contact or temp. My D3 used to have physical pressure switches that were less sensitive to it, but then they also failed over the years.

As mentioned, if you just put key on seat inside, issue solved. Or, leave it in the house/away from car.

There's nothing wrong. There's a sensor that detects your hand when you go to lock or unlock from the door handle. The water hits the sensor and, bingo. Common reaction on all vehicles with keyless entry

Sorry to say but it IS definitely a flaw...
At first I thought my car was having a short circuit because of some water leak via the door handles.
I was really pissed.

Common reaction on all vehicles with keyless entry?? Seriously?
My former BMW was never doing it,
and my current BMW is not doing it either.

Well congratulations BMW for solving this. Please share your technology. My Porsche does the same thing.

All my current cars are keyless but only the Audi does it...

I found that this only happens if the key is in my pocket when washing. If I'm washing at home, I leave the key in the house and then have no issue with unlocking/locking.

Of course it does. Porsche, vw, seat, Audi are sharing the same parts.
You seem pissed because bmw is doing better than the vw group on this.
Audi fanboy ? Grew up man.
