This morning i drove my 2009 A4 2.0t to work.. its a Prem Plus with Nav. and everything was fine.. radio, bluetooth, nav, etc all worked.
i got in the car at lunch time... and the MMI screen didnt turn on... driver information screen showed only my speed.. bluetooth, radio, voice command, rearview camera were all down.
i stopped at a light.. turn off the car.. turned it back on... and still none of the electronics worked.
the car was off for about 30 minutes while i was eating.. and it was fine and working again.. ive driven it 4 times since and it is still working fine.
i called the audi dealer to get an appt but their timing is going to be hard and its 60 miles away from me.
anyone know whats up with my car? or whats going on? is there a way to reboot the system.

No, I just shrugged it off for the moment. Will bring it up at the 15k service soon though. Another interesting incident that I posted about a couple of months ago may be related. Basically all my hvac lights would flash and light up at random like some kind of space ship. It never accurately displayed the settings. I brought it to the dealer, and they didn't believe me at first. Then a day later they told me I was one of the first to report this, but audi is aware of it and is working on a fix. 1 day after getting the car back (nothing was done to it), the problem vanished and was back to normal. Audi's do seem to have their fair share of electrical gremlins. My last A4 would come up with ABS or check engine lights for a day or 2 and then go away. Dealer always had a BS excuse.

im ready to punch Dorothy (my car) in the headlight..
im used to my e46 bmw. I put the fan on setting 2, temp at 72F. it blows out 72F air continuously.. never changes. just keeps going like that.
the audi keeps raising and lowering the fan speed.. and if thinks the car is over 72F... it freaking turns on the COLD AIR..
it was 41F the other morning.. my heat was on 72 F.. fan speed of 5. it turns up the fan and starts putting in cold air... dear god.
i never use the auto mode.. i dont like the car to automatically climate control like that.

The first time it happened, after about 4 months of ownership, it scared the crap out of me.
I immediately restarted the car and the MMI still did not power up.
I restarted it again, and all was normal.
The second time it happened, a few months later, I left the car running and rebooted the MMI and it worked fine. After that, all was normal.
It's a computer. Sometimes this stuff just happens.
It's scary but 99% of the time it's not serious at all and as long as it reboots, there isn't anything your dealer can, or should, do about it.
Now if the MMI fails and will not reboot after a few attempts at using the reboot procedure or multiple restarts, then take it to the dealer for diagnosis.

What you are trying to do is, actually, counterproductive which is why you're not getting the results you want.
The automatic climate control is designed to maintain specific interior temperatures. The more you interfere with it doing the job it's trying to do, the worse it's going to get.
The best thing you can do is set the temp you want and let it do it's job. It will take getting used to. I had to get used to it because I've always hated automatic climate control.
But I DID get used to it and the B8 unit actually does a really great job if you just quit messing with it.
