LR3 Air intake problem

[warlocksk]

Hello,

Hissing noice but cause not found. Can anyone tell me the reason ?
Could this be faulty MAF sensor ?
MAF Sensor is Clean
Throttel is Clean
Air Filter is New
Smoke test no result.

In your video it almost looks like the flexible part running from the air filter to the throttle body is loose. Check all connections. It being loose could create the noise you're hearing.

i checked all connections, they are all okay, no problem there. the noice comes from the hose that i disconnected in the video.

That's the EGR valve. Exhaust gases are rerouted through it. not sure about the level of the noise, but I'd say it's pretty normal.

I compared the noise to other lr3 engines but they do not have this much hissing. Sometimes when departing the car makes kind of a kangaroo effect, i.e. it jumps, therefore i suspect the MAF sensor to be the problem.
