Heating flap, air valve, water in the footroom

Dear Phaeton friends! I put 2 things in one post. 1. Water For days it rains heavily. Today I have found that water is in the footroom (driver side). I tap clogged drain openings in the area engine room directly under the windshield, close to windscreen wiper motor. My car is standing outdoors. I suspect that over time there has accumulated dirt. Does anyone of you know where these drain openings are located? Have already had a bottle cleaning session? The car was now 1 week, of which it has rained more heavily for the last 3 days. 2. Ventilation flaps A bracket is damaged. (PDF, see arrow). The 2 photos are only for illustration. I have from the Internet. Does any of you have an “explosion drawing” for me, on which you can recognize, whether there is the flap as spare part? Possibly with article number? I hope you can remove the flap. Be able to take a photo afterwards. On that you can recognize the defect better. Be happy about answers. Thank you now already in advance. Greeting Kurt
