A-4 Cabriolet-no power windows/trunk or cont. top working
I left my 2003 A4 Cabriolet Audi at the airport for a week and came back from our trip to find a dead battery. We got it jumped but our power windows, trunk and convertible top does not work. On the dashboard, the symbol of a car flashes the hood (in red) over and over.
All the other electrical units work, wipers, radio, horn, lights, etc.
What can be the problem?

Try clearing your codes. My soft top stopped working because the position sensor freaked out and wouldn't open anymore until I cleared the codes. When you jumped your battery it may have fried your central conv. module. I would also run an output test to see if it really is the module. Personally I would've tried to get a new battery, the b6 cabrio is so fragile

remove the battery, re-charge it fully, put back and re-sync the remote.

I have had the same common fault, this is due to water leaks in the passenger side footwell( right hand drive car)this is where the comfort control unit is housed,mine was under water, I cleaned it and sprayed with a water repelant and it worked again,these units are about £700 so get to it as soon as possible to try to stop it corroding. the carpet was dry where it is but underneath it was a swamp, it took me 2 months to find the leak after going through all the forums and none came up with mine. My leak was due to a drain hole in the roof cover seal that covers the roof when down,it is where the seal meets the back window seal, there are 2 drain holes one obvious and one tucked away in the seal, this not so obvious sealwas the culprit, water drains through this and into a channel below, there is a hole in the channel and a plastic adaptor to this hole underneath, the seal around this was gone so all water running down the roof when raining went through this and under the back seat, there are gaps in the steel panelswhich allows the warter to run into the rear footwell and then into the front and swamp the comfort control unit, I hope this helps, I also had to reprogram the key for the central locking but everything else started working by its self.

when the soft top , trunk, windows, and key remotes wont work on a 2003 Audi A4
my 2003 Audi A4 3.0 Cabroilet had the white lights flashing one day. i went out and tried to use my remote to unlock the car and it would not work, both windows will not work, you can not unlock the trunk, nor use the soft top. What could have happened? you have to manually unlock and lock car and manually drop the soft top now. What did you do for yours and did it work?
