Re: WK2 External Air Access?

Thanks for clarifying ED.

Do you know if a "compromised" system needs to be evaluated prior to the nitrogen being replaced, or alternatively if the system is set up that the nitrogen automatically displaces the oxygen as its being refilled? I know someone who was told that evacuation wasn't required, which surprised me.

Cheers,
Steve

Not sure about the evacuation but there is a guy on here that had a leak in one of the plastic nitrogen lines going to the front on his 2014 and it was over $800 just to put a new plastic line on and refill with nitrogen. not sure how much was the refill cost and how much the line was but it sounds like an expensive system to have serviced. Its probably not going to be a $50 visit but I hope it does not cost you too much.

Re: WK2 External Air Access?

I do not believe the system can take in outside air. The FSM clearly says it cannot.. and the uncontrolled moisture would be a disaster..

You have the nitrogen you have, and if it leaks out you are in for a service call. Repeatedly going up and down does not deplete the nitrogen store.

Re: WK2 External Air Access?

We're drifting away from the situation in context now... this needs to be read from the start.

Regarding the accidentally depleted tank, obviously there was still nitrogen in the bags and lines. Say the tank was emptied at Normal Ride Height, there's still an amount of pressurised nitrogen left at xPsi. The tank, I assume, will be at atmosphere (with oxygen) until the control blocks are actuated... and then the two equalise. Now there is a mix of nitrogen and oxygen at xPsi, which will obviously be lower than the what was in the lines beforehand.

- So will the system still run like this? Sounds like it.
- Is it that the compressor must simply run for longer to make adjustments, or not? What are you observing in this regard dikpens?
- How is dikpens system still doing its job? Did it draw in air, or is it just functioning with a lower charge of mixed gases?

I'm really interested to understand. If my system ever fails, I would put money on it being in the middle of nowhere, with no mobile (cell) coverage. I'd like the knowledge to have the best chance of McGuyvering it back to some form of operation.

Cheers,
Steve

WK2 External Air Access?

Steve after I last spoke to you, I decided to try raising the car to OR1 which it did fine but I got a compressor overheating alarm when I tried raising to OR2.
I get my system recharged Thursday, I'll query them about the evac then. Glad you suggested the coupling to fix the nitrogen line, hopefully nitrogen alone will be alot less than $600.

Re: WK2 External Air Access?

Yeah any info you can extract at the dealership would be gold Wade. Hopefully they are a bit chatty and let you in on the procedure. Are you going to Wanneroo for the work?

Cheers,
Steve
