X5 40d Air Filter Housing Missing Part?? Bypass Valve

[neo61uk]

Hi there

Replaced my air filter today and noticed there is a bit missing in air filter housing?
Allowing hot air from engine to reach the air filter.

Ive quickly checked realoem to find out the missing part is called Bypass Valve and comes with cars equipped with Cold Climate Package S842A

Part No 13

My car being UK spec is not a cold climate spec but still i cant believe how this can be right.
The car is sucking the hot air directly from engine bay.

Anyone seen it or can have a quick look if this is missing in their cars as well?

I think it's a part for the car, being a diesel, they might have a hard time starting in the cold. The package might have it so the bypass valve heats the air in the airbox, but I'm not all that sure because we in the US only have the 35d.
