Anyone who deals with Cameras Guns or any precision gear sensitive to moisture normally has it

Heres a gun supplier in Norway -

The beads inside the bag is what you need - only important thing is to get enough as very small bags only have a tiny amount and the beads are small bigger bags are better as they have bigger beads inside.

As far as Im aware theres nothing else about it thats special

Good Luck!

The compressor can be test run without installing it, clamp it down securely and connect a 12 volt battery to it with jump leads, a car compression tester gauge suitably connected will tell you what pressure it will or will not produce.

The compressor is under the car again. The car is at same height as when i took it of, so there is no bag leak.
Anyhow, the compressor won't kick in. Lamp is coming up a few seconds after startup.

"Fixing" stuff without diagnostic tools ist just stupid and throwing away valuable time. Never again.

Can't get the diagnostics running on my computer, geting really tired of this...

@M3DPO - as you can see, i checked the conpressor and it ran without any issues.
Really have to buy wiring diagrams! Any help where i can get rhem?

Have you checked all the fuses and temporary swaped the relay for one that is known good, heated screen I believe is the same Thumbs Up
Test for power at the compressor plug with a 12v bulb and two pieces of wire if you don't have anything else, at least it will point you in the right direction. Don't lower the suspension to access height as you may not be able to get it back to normal and you will be really "off road", as least you can drive it at the moment if needed at normal height.

Yes, checked the fuses in the engine room and switched relay. If i remember right it was the same relay as my heated windscreen relay.

The compressor normaly starts when you start the engine? If so i would measure under the car later. ๐Ÿ‘Œ

If you unplug the compressor under the car, put two cables into the plug and run them outside the car for safety connected to a 12v bulb at least it will tell you if you have power going into the compressor.

Did you test run the compressor before you re-fitted it?- it seems there is an element of confusion, you originally say that you could not hear the compressor running, which may be a different problem from the light coming on.
If you have power at the compressor it's the compressor that is faulty, if you don't you have power supply/wiring fault, you have got to eliminate one or the other or you will be going round in rings forever Thumbs Up
If you don't have power at the compressor and you have checked the fuses and relay check the cable joint behind the left side(sat in the car) front wheel arch liner, in front of the compressor air tank.

Just remove the relay and short out the two big contacts with a lenght of wire with ignition on, this should run the pump and tell you that the power supply is getting there.

Flack Thumbs Up

After i was stuck in the snow and parked the car i did not look at the heights car...

I then i shorted the compressor with ignition and today morning i realized that the car is much lower in the front than in the back.
Rear end is now at off road mode or higher. Front is much lowe
I can post a picture later.

I'll start the compressor one more time later and see if the car lifts up in front. Or shouldn't i?
I leave for a week tomorrow, would be nice to figure something out t tonight. Smile

Shorten the compressor won't lift the car in front. i have a feeling it's a pressure sensor or the valve block.

Anyway i won't do anything before i have run diagnostics. Waste of time.
