Hey guys! I just installed the Corsa Xpipe last night on my A8 and the whole way home from the shop (about 17 miles) I had no CEL all good. This morning on my way to the gym (<1 mile) it turned to v4 mode a few times and threw a CEL. And yes I did plug in the old AFM actuators and zip tied them up in the car. It might just be that the zip ties got in the way of the actuators but am I going to have to clear the CEL or will it automatically go away if I fix the afm issue?

Did you check the cel? Make sure it's for the exhaust first. It should go away though after a little bit if you fix the issue but having it cleared shouldn't take more then a couple minutes.

P0409 Cat Below Threshold, I'd presume. It's drivers side where the X slips on the cat. You took off the copper braided gasket on the cat pipe I bet, right? Had same/did same. Dealership fixed it. 200 miles, no code, new cat with the braided copper gasket.
