Entfernung von Drallklappen / VSA / Einlasskanalklappen

Entfernung von Wirbelschleppen (auch bekannt als VSA or intake runner flap delete) is a
professional ECU calibration service that disables the control and diagnostic routines of variable intake
manifold flaps. These flaps are designed to improve air turbulence and combustion efficiency at low engine
speed, but on many vehicles—especially from the VAG-Gruppe, BMW, Mercedes, Alfa Romeo und Fiat—
they are prone to wear, carbon buildup, and mechanical failure.

When the swirl or intake flaps stick or break, they can cause performance loss, check engine lights, or even
serious engine damage if fragments are ingested by the cylinders. Instead of replacing the entire intake manifold
(often costly), a proper Wirbelklappe entfernen through ECU software ensures the flaps are fully
deactivated electronically and that no related diagnostic trouble codes (DTCs) appear.

So funktioniert die Entfernung von Wirbelschleppen

Unser Wirbelklappe löschen solution disables both the actuator control and position feedback diagnostics
inside the ECU. This allows the flaps to be safely disconnected or physically removed without triggering warning
lights or limp mode. The modification is performed directly in the ECU software—
auf dem Prüfstand getestet und dyno-geprüft—to maintain full drivability and proper intake management under all
operating conditions. Whenever necessary, we also provide notes for mechanical blanking or linkage removal.

Wenn die Entfernung der Wirbelschleppe empfohlen wird

• Seized, broken, or faulty swirl flaps with DTCs P2004-P2015.
• Damaged actuator motor or linkage causing unstable idle or airflow imbalance.
• Heavy carbon buildup restricting airflow.
• During performance tuning or combined DPF/EGR delete for a cleaner air path.

Vorteile und technische Hinweise

• Eliminates swirl-flap-related error codes and limp mode.
• Prevents dangerous intake failures from flap breakage.
• Improves reliability and reduces intake restrictions.
• Recommended for motorsport/off-road applications.

Das ist wichtig: Die Entfernung von Wirbelschleppen ist vorgesehen für Einsatz im Gelände oder im Motorsport, oder
where allowed by local laws. Safety systems and fueling logic remain fully functional.
