Exhaust Flap Actuator Spring Repair Kit | Land Rover & Benz

Fix That Exhaust Rattle Without Replacing the Whole Actuator

Hearing an annoying rattle from your exhaust? Got a dashboard warning light for an exhaust actuator valve error? Don't spend hundreds at the dealer — this Electronic Exhaust Flap Actuator Spring Repair Kit lets you replace just the broken spring at a fraction of the cost.

Vehicles with an active exhaust system use an electronic servomotor actuator with an internal spring to control the valve inside the exhaust pipe. Over time, this spring breaks due to heat exposure and normal wear and tear — triggering a rattle noise and/or a check engine light. Dealers typically require you to buy an entirely new actuator unit, which can be very expensive. This kit solves the problem by providing the replacement spring you actually need.
