Fault code after swirl flap delete
After removing my swirl flaps i get the below fault code and my car goes into limp mode on every start up. If i delete the code after firing up the engine the car runs fine until i turn it off. Any ideas how to fix this issue?

Why did you remove them ? Which components ? Just the flaps, or the flaps + shaft, or perhaps the actuator as well ?
Unlike the previous engine generations they are no longer regarded as a significant risk. The ECU will throw an error code when it is not able to validate that the swirl flap actuation signal has resulted in a mechanical action. I expect you'll need to have the flaps coded-out, but that will typically mean a visit to a specialist tuner.
