Thread: Llams and Air Up

Llams will only raise the vehicle if the air suspension system is working as it relies on the self-levelling aspect of the system. If height is being limited due to a speed restriction or a fault reported by ABS, ie not an actual suspension system fault, then Llams can cause the vehicle to be raised.

Llams is ideal for regular use whereas air-up is a backup if the suspension system has failed.

Brad,

Llams is not primarily a fault recovery system, even though it has this ability in certain situations.
Llams puts suspension height control more in the driver's hands.
In addition, Llams can assist with electrical issues in that it will raise a vehicle with lowered suspension resulting from certain electrical faults as per Graeme's post.

Regarding an "air up" kit, I assume you mean the GOE emergency air system. This kit is specifically designed to assist recovery from "mechanical" issues with the suspension system.
It has components to repair broken air lines and/or isolate the air springs, which typically remain sound when other system elements are failed or broken (e.g. valves or compressor).

However, in some cases there is overlap between capabilities.
You could use the air up system to isolate the air springs when the electrical system is faulting by pulling the appropriate fuses and manually inflating the springs.
And Llams would allow a similar recovery but I think in that scenario Llams would be the easier option for recovery.
On the other hand, Llams won't help much if the compressor is struggling or failed.

Anyway, I have both because I see scenarios applicable to both. Llams I use regularly and touch wood I haven't used the air up kit at all.

Cheers,
Scott

Hi Brad
The two are different

LLAMS is used to modify ride height on the fly allowing you to travel at speed at off road heights. Also does lots of other handy stuff including a recovery mode which will lift you off the bump stops if you have a height sensor problem. It won't help if you compressor fails or you have some other fault in the front or rear valve block for instance.

The air up kit (assuming your talking about one of the GOE kits). This is an emergency air up kit used to bypass everything except the airbags. So if you have a compressor failure, valve block, unknown leak or suspension ecu problems you can manually pump up each airbag to get you out of trouble.

Thank you for the replies.

I am now a little more educated, and think i will start with the Llams and see how i go. I might consider the Small EAS as a backup.

Cheers

A single failed height sensor wont cause the vehicle to drop to the bump-stops, only preventing levelling adjustments between height mode changes which therefore includes any Llams height change requests until the next height mode change. Recovery mode provides off-road height on the high setting and normal height on medium when a failed wheel speed sensor or steering angle plausibility fault occurs for which the suspension is lowered to safe/access height. Without recovery mode, the Llams high setting only gets the vehicle back to normal height.

If the vehicle has dropped to the bump-stops them Llams can't help.

I've had 2 failed height sensors. The first was whilst I was on my way back from a 4 week trip in SA towing a van. The failure mode of the sensor was such that the EAS was continually trying to add air to the front drivers side corner. Eventually the compressor overheated and down onto the bump stops she went!! It was a long and costly tow from Gundagai back to Sydney!! NRMA premium membership was worth its wait in gold. I bought the GOE's emergency air up kit (full version) although I still haven't fitted it yet

I think just pulling the EAS fuses would have kept you going in this case.

Funny you should say that Scott. I rang my indie LR mechanic when it happened to see if there was anything I could do but he didn't know. I hadn't had the car long at the time so I didn't know much about how everything worked. When I got back I did a bit of research and your right, pulling the fuses once the compressor cooled down a bit would have got me home. I think this is something every Disco owner with EAS should know.
