Air suspension not working/car bouncing all over
« on: 06 October 2009, 23:02:23 »

Hello I've just got an Omega 3.0 MV6 Elite Auto. It's got the air suspension but doesn't seem to be working as it bounces all over (especially after speed bumps), understeers, and doesn't handle too well (my Senator was better). There is
also a residue coming from the rear shocks. Is it broken and how much will it cost to fix? Shall I replace the whole lot with Bilstein suspension rendering the ride height adjustment inoperable? Any help appreciated, Thanks.

self levelling shocks failed. Mine went the same way, oil leaked out and lost all damping. Back started banging as the wheels bounced off the road surface, and loss of grip was noticeable.

Trouble is only vx make the self level shocks and they aint cheap. £300 for the pair or 150 a pair with a trade club card, see link at the bottom of my post for the abs trade club card. It 20 sobs p.a. But well worth it, other items from vx are well cheap like oil and plugs etc.

Or you could just fit standard shocks and pull the self level fuse, but you'll also loose the rear 12v socket which runs off that fuse as well. Or it does on mine anyway.
Hth :-)

Flee bay item 230232503729Comes with pipes and air gauge and valve so you can adjust the pressure with a airline.Might not work with the compressor on a miggy.so your self levelling wont work.I have these Monroes fitted to a Caddy Seville years ago and they worked better than the standard Caddy air shocks.   £189.00 plus p&p at £19.99

Rusty - those are keen prices for VX none self levelling shock absorbers.

My take is that there are three options open to anyone with self levelling rear suspension.

1. Fit Vx replacement shocks preferably after getting them through TC.
2. Dispense with the self levelling as said above by disabling the compressor and fitting standard none levelling shocks from whatever supplier. There are plenty of recommendations on here.
3. Fit "gas" shocks like these 200255504662 on the bay uk. for £90 plus postage. As I understand it you manually inflate those at an airline for carrying big loads and then let the pressure down for trolling around lightly loaded.

Are the steel springs fitted to a car with self levelling suspension weaker than standard? If you choose option 2. then do you also need to fit heavier springs?

Funny you should say that, i fitted  mv6 suspension to mine with new mv6 rear shocks about 3 months ago. But i never fitted the rear mv6 springs,never got round to it, so it was left with elite springs, and all else was mv6.

Anyway, the back was sitting a bit low, nothing major, about 10cm lower than the front this got worse when loaded, and the back was a bit choppy so i re fitted the self levelers just before Newent, also wanted my rear 12v pocket back. I left the old mv6 shocks in the garage standing the correct way up in the corner of the garage. Point is i've just noticed, when out there today, they are both leaking oil. Looks like they have both failed. Never noticed this when i removed them.

This would imply that mv6 shocks and probably stock shocks(?) dont work with elite springs which are softer from what i gather, like you say.

Seems too great a coincidence for both to fail in the same way....

Ok thanks everyone for your advice. Think I'll get the air shocks on ebay. Will I need new springs aswell ( will they have been damaged or affected somehow due to the lack of damping? ) Thanks again.

If you know someone with a Trade Club  :-/  :-/  ;) card they could buy the proper OE dampers for less.
Depends where in the counrty you are.  :y

Springs will be fine. But it would seem matching the damping rate is important maybe? With that in mind, would suggest sticking to the original parts.

If you fill in your profile with your location maybe a member with a trade club card near you can buy them on your behalf.

 Or subscribe yourself using the link at the bottom of my post. Card costs £20 pa via direct debit and gives major savings on most serviceable items. That would give you your self levelling shocks with the cars existing system and a tc card for £170.

They are very easy to fit diy. 15 mill top nut and 22 mill bottom bolt iirc and the air line is a very simple clip  :-)

Hi all,
Just like to say what a fabulous forum this is for some really helpfull info for the less experienced Mig owners.
I've been searching for info on Self levelling set up and came across this thread above. I haven't had my Elite that long and am working my way round finding out why the previous owner probably decided it was time to pass it on - hay ho too late now...
Anyway - I've checked today to see if the self levelling is working properly - as per the very helpful guide in the maint section (by removing the link arm on the sensor underneath) - and absolutely no movement at all. So question: how do you tell if it's the pump, air line or shocks that are leaking ?
Now I've noticed on the thread above that by removing a fuse you can disable the self levelling - coincidentally I've found out this week that the rear 12v socket isn't working but hadn't thought to relate it to this until now.
So back to my previous question - assuming the fuse is why the above test didn't work in the first place - where is it and what am I looking for when I've put it back in and the above test still soesn't work - pump or shocks ?  :-X

Cheers
Ian.
