Hi Mate,

I installed BMW factory airbags and reservoirs in the back end of my E53 3.0d this weekend. At this stage, I'm just manually inflating them.

Can I ask where you bought your fittings from? I had to fabricate something fairly dodgy to mate the 4mm air hose from the BMW reservoir, to the 5/16 12 bar hose I had. I'd like to put in something better quality..

Also, how many PSI do you inflate the rear bags up to? It appears about 80PSI or so, I'm back to near factory ride height..

CHeers + thanks,
Scott.

Question for you - with our lovely Winnipeg roads that we have here, I've being wondering about suspension changes for my X. It currently has the sport package, which was great when I was living in BC with their nice smooth roads, but I'm finding it pretty harsh on these roads. When you switched from the OE setup to bags, did you notice an improvement in the X's ability to soak up bumps?

I'm thinking it you have the bags inflated to a happy medium ride height - not so low that you have no travel and not too high that they are infalted to a high PSI - that it might be nicer then the ride I currently have...I could be way off base, I have no experience with bagged rides.

Maybe once we both have our summer wheels on, we could do a little back-to-back road tests between the two to compare? might be interesting

Thanks!

Yeah, the roads here are bad....

Here's the bad news: as far as SUV's (SAV's) go, the X is on the "firm" end of the spectrum when it comes to ride quality. If you happen to live in an area where roads look like they were subject to a Grenade hauling driving around losing it's cargo (aka 90% of our roads here)...the X's suspension isn't really going to help your case. It's really just the nature of the beast.

Here's the good news: The one thing I immediately noticed after switching to air was that the bags seem to filter out more of the road vibrations that the springs transmit. As for soaking up bumps, I've noticed that in my "High" setting (more or less standard ride height of a factory 3.0) it does take bumps a bit better than my lowered ride height...but both better than the coils IMO. Whether or not it would be enough to justify the cost, It would be your call! (I'd do it all over again without hesitation!!)


My X is apart in the garage at the moment as I'm working on some upgrades to my air system amongst other things....but I'm hoping to have it back on the road by the 25th (that includes summer wheels on with the exterior clayed, compounded, sealed & waxed). We can definitely head out after that!!

I'm not sure it would be worth the cost either...but this might justify a 4.8is with factory bags amongst other reasons...mainly the POWERRRR (in the words of Jeremy Clarkson)

My summer wheels won't go on for a bit either, waiting until it gets a bit warmer and stays that way! Maybe sometime in May we can check out each other's Xs

Time for an update!

Ok guys, so it's been about 3 years now with my current air setup and while I had a couple small quirks along the way to sort out (which were directly related to the awesome climate I'm situated in where it routinely dips to below -30), the system is still kicking and working flawlessly!

That being said though, over the past couple months I've enjoyed a certain level of refinement on another air system (2011 Sport Autobiography) which left me thinking that perhaps it's time to do some refining of my own to the X's setup. Now before anyone starts with the "see, that's what you get for having air suspension" let me first say this system is still 100% functional, and this is upgrade is only to REFINE it further! I am still a huge proponent for air suspension and the benefits/versatility it offers.

This V2.0 set up will encompass a few changes:

1) Higher pressure (110psi on, 145psi off vs current 90/120psi)
2) Larger air reserve (2-3 gallon tanks vs. current single 2 gallon)
3) Addition of 4-corner bag pressure monitoring to current height based system.
4) Addition of coalescing filter & larger desiccant dryer
5) Accuair VU4 valve block
6) Dual 3/8" supply lines to valve block

While my system will still remain primarily a height based system, adding in the 4 pressure sensors (one for each bag) will permit me to set limits on bag pressure differentials between sides as well as set low pressure warnings for each bag. This further reduces the chance of cross-loading, and prohibits the suspension from trying to over fill a bag in an attempt to level the vehicle out on uneven ground or steep inclines....think of it as having a system that is now "seeing with both eyes".

The higher pressures & increased air reserve will make height changes faster and permit more changes before the compressor needs to kick in.

The addition of the Coalescing filter & desiccant dryer will ensure the valves are seeing clean, dry air...which is crucial for any air operated system!!

When all is said and done, this new air management setup should rival the speed that I've become accustomed to on the AB, without any of the drawbacks of having a system fully integrated into the vehicles electrical system.

I still have a few mounting brackets to finish drawing up on autoCAD....then its to the water jet & CNC break Monday before being TIG welded into the air management box Tuesday!

Here's a couple teasers:

Sizing up everything for clearances...everything relating to my air management will be housed inside the aluminum box :



...And yes, I am ditching my spare for a slime kit.

Playing a puzzle game....trying to figure out the best/eye appealing way to mount the big stuff inside the Management box:



Stay tuned for more in the coming week!

@RB - Thanks dude! Most of this stuff is old news to you already! haha...you're gonna love this project; OCD special special comin right up!

Jhay - Maaaaan I hope we're finally done with the snow....summers are short enough to begin with!


Micro-Update:

The Bad news: Life's getting in the way this week, and as such progress has been slightly slower than anticipated.

The Good news: First of 3 brackets is ready to be welded. Here's a quick shot of my 3D AC model & actual piece.









Tomorrow is fitting-shopping day. Once I've got an idea as to fitting space requirements I can knock out the remaining brackets and send everything out to get welded into the box. Before final assembly.

...Stay tuned!

-S

man i would love an air ride some day. but i dont think id have the necessary tools or knowledge for one. maybe a cheaper alternative for me. or maybe even a manual set up, your the man to talk to Spence.
if i plan on doing something air worthy, ill def seek your advice and help.
did you go kit or source things out yourself? also looks with the above doing your own work...wicked!
