Range Rover 2011 5.0 Rear Airbags

[TomoThomson]

Hi

My RR REAR suspension leaks down over night on both sides I(E left and right hand sides)

Pumps up fine when engine started with DD closed

Is this one airbag fault or is it something else common to both rear airbags

I haven’t sprayed soapy water around the bags etc

No codes get thrown up …

Lets know if you know what’s wrong

Thanks
Pete

I had the same issue but on the front on the same model as you. I replaced the front electronic air control valve and it fixed the problem. Not sure where the rear valve is located. There is also a centre one from my understanding that presumably feeds front and rear.

Thanks

I got lucky and cycled the suspension high and low a few times and it’s fixed (Will prob reoccur)

Cheers

At a guess I’d say it’s the desiccant in the air dryer travelling through the system due to age and probably stopped a valve closing properly. By raising and lowering it a few times it probably blew it along a bit. I know some people try to clean them out / replace the desiccant in the dryer etc but I tend to take the path of least resistance with my 2011 rrsc as I find a lot of things seem to resolve themselves lol and save my energy for real issues.
