WK2 External Air Access?

Hi, is there anyone who has tapped into the adventure package compressed air system on the GC? Would like to have an external air chuck, to air up tires, etc..

Thx!

It's a closed loop system - your not able to tap a line into it.

Just yesterday I was hunting for the same in my Wk2. Just behind the backseat underneath the panels, I found a male port, but inside it is like the inside of your tyres valve. The pipe of my aftermarket 4x4 12v compressor fits perfectly, but it has no adaptor inside to push open the valve inside the male fitting. Im going to change the fitting on the air tank behinde the backseat, and also fit a small tape like lever valve. So when i want to pump my tyres after sand driving, just fit my pipe, which is store under the backseat, open the valve and do some pumping!
I noticed on the tank, the operating pressure is 16 Bar, so it will do the job.

Re: WK2 External Air Access?

The system is nitrogen filled, and can not draw in. It is "closed" as stated above, and the pump only recirculates.

So your tyres may go up, but your car will go down.

Cheers,
Steve

I would suspect that the pressure is being held within the individual front and rear systems... isolated from the now depleted tank via the control block.

Cheers,
Steve

Re: WK2 External Air Access?

Barboots is right, I'd avoid raising or lowering your suspension until you get the tank refilled or you may need a tow truck to get it to the dealership.

Re: WK2 External Air Access?

How did you go getting a nitrogen fill in South Africa dikpens? Or has your ride height remained OK despite venting the system?

Cheers,
Steve

Steve, I went driving in the sand dunes this weekend, after draining the tank, and I was happy to see, that the car went through all height levels without any problem or delay. Also I pulled the J06 fuse and noticed a big difference. This was the first dunedrive after I fitted my new 275/65/18 Cooper ST MAXX!!! Tyres performe Gr8. My GC head 20" stock and that didnt fly at all in the sand.Will post a small clip shortly.

Re: WK2 External Air Access?

That's got me stumped, but I'm pleased there's been no problem. Did you repressurise the tank with your air compressor perhaps? Your experience goes against the general information on the system, and I'd really like to understand in the event of trouble when in the outback!

Some people claim good results from the 20"s in sand... I changed to 18"s as well because it's often extremely powdery here on the Western Australian coast. Plus I'd be worried about the small amount of sidewall height in when in the bush.

It'd be cool to see your video or some pictures.

Cheers,
Steve

Re: WK2 External Air Access?

The system has the ability to make up for lost nitrogen by drawing in and compressing outside air. Using the Jeeps closed nitrogen system as an air source is a bad idea because the replenished air has contaminants and moisture that will now accumulate in the system. It will get worse each time the closed system's air is replenished. This is not how it was designed to be used and will likely cause damage in the long run.
