What is this??

[Flipman]

Hello!

Was looking under the glove box today and found these
strange things..
Looks like it some sort of vacuum attached to it.




Also found this connector laying under there.

Anyone know what these things are?
That would be great!!

I think the first one, with the vacuum attachment is to do with your HVAC system. Similar to the C4 vacuum solenoids shown in the photo below. If you can find and post the PN of the device, we can be more accurate.

The connector, I am not sure.

Forget about the "Mystery Box in Question" label. (It is the later C4 main HVAC air flap motor).

If I remember correctly, wiring loom with yellow tape around it is for engine/ecu. By quick look in wiring diagrams it can be connector T6d: http://www.s2central.net/S2_Schematics/B/B73-03.pdf

Thanks alot!

I think you have right.. should it not be a 3rd hose connected?
As you can se in picture the front one has no hose connected.

And as you can see in my photo, some of the "legs" (or "nipples") do no have any hoses attached to them.

Again, supplying a PN with your question makes for a better answer.

Okey!

It has 4 wires, do you know what it should be connected to?
I can't really find anything it should be connected to.

I can try to see what the wire colors are.

Schematics says T6d is coding plug and isn't connected anywhere. Wire colors would be good.

It could be similar to the UrS4/S6s that have a "coding" plug as shown below. For the North American UrS4/S6s, the red plug was connected to the black plug, jumping some wires. This limited the vehicle speed to 130 mph (208 kph) in case owners only put on "H"-rated tires instead of "V"-rated tires (the Option UrS4 15" six-spoke Speedlines came with H-rated tires, for example). The plug in question might have been set up for similar duty but was never used. (In NAmerica, you remove the red plug and the vehicle speed is only limited by engine hp, road conditions, and cajones).

The vaccum thing there is a membrane that opens and closes the air recirculation flap.

Took a closer look at the "thing" today, and googled the PN. (437906283A)
And as sküll says, it's a soleniod valve for air re-circulation.
Thanks anyway!

In fact 437906283A is the same valve that showed in my photo to the right of the mystery box. Vacuum solenoid valve.
