Disco 2 TOWING ON AIR SPRINGS

This site contains affiliate links for which LandyZone may be compensated if you make a purchase.
Springs and shocks are all new air bags 3 month old all standard height
Shocks are cellular damper but prior to them tried terraforma.
All new bushes completely. New watts linkage new tyres new steering box, suspension geometry laser tested and set,
I'd prefer to keep the air suspension which was why I've spent a fortune on other parts but the truth of it is it feels like the bags inflate and deflate causing the see saw.
Once pumped up can the bags be isolated from the supply to eliminate the feeling of inflation/deflation
 
If you have tester set it to coils after it's levelled with the caravan attached then drive it, that would be a good test, if no tester you have to unplug the valve connectors in the compressor housing and remove the compressor relay, then there will be no SLS activity.
 
34 in rear
30 in front.
As an update I've used the tester to tell the car it's on coils instead of air springs which basically isolate's the spring from the compressor and stops the compressor running and it feels a lot less twitchy even without the caravan attached so in my opinion the issue is definitely with the air suspension.
 
I think you are a bit low
Solo I run 30 F / 40 R
Towing I run 32F / 46 R
I never have any issues, the only time mine did fell a bit strange was when i had a slow puncher and one of the rears had dropped down to 20
 
Are your new ride height sensors set up right.
James told me if you disconnect batt when fitting new ones all should be ok.
But i had it in mind if your unlucky you need to plug in and set them up

The only problem is that the SLS has a certain delay (around 5 seconds) between it gets the sensor inputs and goes to levelling mode especially to not react on sudden movements so it should not do what you described unless there's some management issue...are yoiu sure that it's not only an autosuggestion?

Whats an autosuggestion?
 
o_O:( I didnt want to offend you just to make sure, it's the first time i see somebody blaming SLS for towing issues that's why i asked, you should have just said ''yes'' and i could have gave you a simple solution... if that's your attitude then bin the SLS after you invested much in it then come back and glorify the supremacy of coils :mad:, never underestimate the versatility of human mind, it's named ''Cognitive dissonance - the engine of self-justification" , exactly like when somebody converst ACE to conventional anti roll then sais that there's no difference in the vehicle's behaviour :mad: ..... btw i have a degree in psychology :rolleyes:
 
You need to take a step back and put some thought into whats happening its got to be a simple problem.
As for coils air suspension is by miles better.
Forget the trailer and tyre pressure its neither

it would take more than a few words from you to offend me, but if you have a solution for the problem and are unwilling to enlighten others until they beg for the answer then I'm afraid your going to be waiting a long time. Enjoy your ego
