Audi intake manifold plugs for 1.8 TFSi engines

Swirl flaps are components used in diesel engines whose primary function is to introduce turbulence into the airflow entering the combustion chamber in order to improve combustion efficiency. Unfortunately, these flaps have many drawbacks.
   First, swirl flaps are engine components that are subject to heavy wear and are prone to failure. Their failure can lead to serious engine performance issues, such as a loss of power, noise, or vibration.
   Second, swirl flaps, even when open, significantly restrict airflow, which creates additional resistance and reduces combustion efficiency. In particular, when an engine is modified to increase power and torque, swirl flaps become a major limitation on engine performance.
   Finally, swirl flaps are also expensive to repair or replace. Removing them and replacing them with plugs is a popular modification among automotive enthusiasts who want to boost their engine’s performance and avoid costly repairs.

This repair kit should resolve the following error codes:

P1018, 012597, P3135, P2008, P2011, 004120.

These error codes are related to malfunctions in the swirl flaps or their position sensors, which can lead to various issues, such as a blown actuator motor or an oil leak.

P2008 and P2011 indicate that the swirl flaps in bank 1 or 2 are stuck, while code 004120 indicates a problem with the swirl flaps in bank 2. P1018 refers to an incorrect signal from the swirl flap position sensor in bank 1, while code 012597 indicates engine malfunctions that may be caused, among other things, by stuck swirl flaps.

Code P3135 also pertains to the swirl flap position sensor, which has not reached the required position, which may lead to various engine-related issues.
