Okay, so I just snaked the bore scope through the cabin and clipped it to the exhaust so I could see the flaps while driving. They definetly aren't functioning. I started the car, and drove it around the block 1st, 2nd, and 3rd at varying RPM while in comfort and normal mode. The flaps stayed open the whole time.
Since the coding shows that the auto flaps should be enabled currently, and ideas as to why they wouldn't be opening and closing?
Edit: Spoke to the previous owner. He had coded the valves open when he initially did the s3 res delete, but the drone was too much for him and he immediately coded it back. He said they work working normally after that. I'm wondering if when I was rear ended the motors got damaged or wiring disconnected. Any tips on diagnosing that?
