Hi all , the rear of my 05 l322 keeps deflating both sides when left parked up for 2 or 3 days no lights on the dash when i start it up it all
goes back to normal and is grand all day it seems to go down very slowly like you never notice it till its down i had a problem with the cruise control not working all the time and the radio controls frozen but they came back working any ideas thanks.

you've got a leak somewhere. If its worse when its the coldest days that's a clear sign of a leak most likely in the air bag. Can be tricky trying to find the leak. When the air bag blows you'll know b/c it will throw a suspension fault and put you on bump stops 2014 FF Autobiography 5.0 SC

No faults shown dont think its the bags had a good luck

As above, you won’t get a fault till it blows.....then it’s, well, obvious, so no fault message really needed.

I think people tend to live with it, or you can spray soapy water on the bags etc and look for bubbles.

Sounds like a leak to me. Just because you can't see it doesn't mean it isn't there.

I'd be putting the car in off road mode and spaying the bags with soapy water / plumbers leak detection spray and having a real good look at them - both.

If it is a leak, you're not getting any warning lights because the car doesn't (yet) know that anything is wrong. What'd worry me is that your air compressor will be working a lot harder than it needs to in order to keep the bags inflated. It could end up being a bigger bill than you'd want.

You still on the original bags? I'd say 15 years is a good run.

Just replaced my fronts after 13 years. One had a leak, the other was fine - but no sense in doing only one. No warnings at all relating to the inflation (or not). A couple of error messages caused by the blocked compressor exhaust fitting - but that's a totally different issue.

Cheers for that did spray l
soapy water on them no luck

Look for leaks at the junction boxes too where the lines hook up. 2014 FF Autobiography 5.0 SC
