Hello together, since Monday I have a problem with my Seat Ibiza 6J. There is a flap in the interior security box. It sounds like a relay is constantly being tightened or dropped again. The problem suddenly occurred under the ride and I can’t understand it. When reading out the fault memory, the device shows an error “P3006 Relais 2 additional heating”. I have already installed or installed a new relay, but the flap is still existing. I can’t restrict when it occurs or when it doesn’t occur. However, when I’m driving on the highway, there’s no flapping to hear. I don’t notice any restriction when driving. Also, the normal heating, rear window heating and seat heating work perfectly. Would be great if someone could help me further. I’m at the end with ideas about what it might be. Thank you! Greetings Tanja
