Endeavour intake manifold flap control issue
Summary of the thread
The conversation centers around a 2009 Ford Endeavour diesel experiencing reduced engine power, rough running, jerking during acceleration, a loud hissing sound, and increased fuel consumption. The suspected cause is a faulty intake manifold flap control mechanism, specifically the switch that controls the manifold flaps. A similar issue was resolved by replacing a defective switch, which was confirmed by a workshop diagnosis. The suggested solution is to have the switch repaired or replaced by professionals.

When you say 'flap control mechanism,' are you referring to the switch that controls the manifold flaps? I've read that a defective switch could be the culprit. Is that what you experienced, and if so, were the symptoms consistent with what I'm observing?

Yes, that's exactly what I'm referring to. In my case, it turned out to be a faulty switch. The symptoms were very similar to yours: hesitation, hissing, and generally poor engine performance. Honestly, unless you're very comfortable working on engines, I'd suggest taking it to a workshop. It can be tricky to diagnose and repair properly. It is possible, but for me, getting the workshop to do it was the best option.

I appreciate the confirmation. I suspected as much, given the symptoms. I've taken your advice and booked it in to a workshop. They have identified the switch intake manifold control as defective, and quoted a repair cost of 465€. Thank you for your assistance!

I had similar symptoms with my Endeavour (though it was a petrol engine). Reduced power, rough running – sounds very much like an intake manifold issue. Have you checked the flap control mechanism itself? Sometimes they can get stuck or the actuator motor can fail. The intake manifold's flaps help control the airflow into the engine. When they aren't working correctly, it can mess with your engine's performance quite a bit.
