Thread: Can ACE raise the front of a Discovery 2? Or just airbags lowering rear?

I have ACE and SLS.

Yes it’s normal for the SLS to adjust height sometimes when stopped at the lights etc. So looking over the bonnet it can appear like the front is changing height, which it’s not.

No sudden movements from or rear should be felt so something isn’t right there!

Correct me if I'm wrong here, but I always believed ACE would correct from side to side, not front to rear.

SLS will definitely respond to braking etc as the height sensors move.

ACE is simply an hydraulicly, self adjusting/reactive sway bar.

It can't raise the front as there is no device to raise it, only the rear bags can be adjusted.

Thanks everyone!

OK, so sounds like SLS might be a bit buggered?

But ACE has no part in it, right? (How does one troubleshoot ACE to know if it's actually fully working? Or is only semi-working?)

For troubleshooting SLS:
1) I'll spray some soapy water onto the airbags? They don't lower when left unused for a few days, so not sure how this can help.
2) But how can I check if it's maybe malfunctioning sensors?

I'll add:

That 'pop' that I sometimes get feels like something getting loose. Like a coil/shock or some other part? But shocks aren't leaking and a mechanic in Sydney did the upper ball joints a month ago and had a look then. But I wasn't getting that pop back then, it's pretty recent.

But yeah, maybe it's the airbags dropping a few mm for whatever reason, but both at the same time like that?

Any problems with ACE should illuminate the amber light, bottom left of the instrument cluster.
Have you got a Nanocom?
