What is a swirl actuator?
Operation. Swirl flap position is adjusted by an electrical or vacuum-actuated servo mechanism which is under the control of the engine management system. Their purpose is to ensure that the air entering the cylinder is sufficiently turbulent for good fuel-air mixing even at low engine speeds.
What should I do about my intake manifold swirl flap?
The intake manifold needs to be inspected to ensure no excessive carbon deposits are present on the intake swirl flaps themselves. This could lead to binding and inconsistent operation even after the repairs and enhancements are completed. A simple cleaning with common intake aerosol cleaners is recommended anytime the manifold is serviced.
What causes intake flap to break on M272?
Please try again later. A common failure inherent to intake manifold 272 140 2401 found in Mercedes-Benz M272 V6 & M273 V8 engines is breakage of the actuating mechanisms on the intake swirl flap system. These flaps are designed to create intake flow turbulence improving low speed engine performance, enhancing fuel economy, and reducing emissions.
Is the swirl flap actuator on 2016 Cooper D still working?
I have a 2016 Cooper D 50k miles the car intermittently loses power around 60mph and takes a few seconds to pick up over 2k revs. It has been into a main dealer several times and they advised they have replaced the actuator as “goodwill”. The problem is still occurring therefore I asked an independent garage to have a look.
