SLS problem doing my head in

[Timmy]

So I've been chasing an SLS problem. Please don't tell me to change to coils, I actually changed back to SLS after the last owner converted.

I've just changed both rear air bags for brand new contitechs. I've also replumbed the whole air harness from bags to compressor. Confirmed no leaks in either bag, or either fitting on each bag with soapy water.

Car will stay inflated overnight. As soon as I unlock and open door, car will deflate to bump stops.

I've swapped the left height sensor out for another used one as I was getting some strange readings on the nanocom (015 instead of 130 where I had set it). I think it may not have been plugged in correctly.

So do people think it is height sensors or something in valve body, or even the slabs ecu?

Wow,this is a new one,watching with interest,I presume you can hear air being exhausted when you open the door.
Will it stay inflated if you leave it unlocked overnight.
unhook the battery for half an hour whilst it is inflated,see if it droppes when you hook the battery up,dont forget the radio code.

[Timmy]

Yep sure can!

Can't think of all the options in the slabs menu, but why don't you try a factory reset? I get the impression that it may have been programmed to allow a Shorty easy access/ egress.

[Timmy]

That's a good thought.
I actually have a late model slabs ecu to go in when I convert cdl. Maybe I should just put that in now!

[lewy]

Have you told the slabs that you have put the air back in

[Timmy]

Sure have. It has been working for a few months now. Sorry, WAS working...

How old is the firmware on your nanocom? I had exactly the same issue and it turned out to be that the auto height setting wasn't being stored in the car due to issues with my nanocom's software being old. Essentially (from memory here and it was 3 years ago) when you set the height you had to select the reset to bumpstops setting rather than saving the height as the buttons had been reversed on the screen but not in the software. So choosing one actually meant selecting the opposite. Does that make sense? I found the firmware issue on one of the UK forums. Updating the nanocom sorted my issue. Might be worth checking.

[Timmy]

I have just updated to the latest (1.29 from memory). As I also had read that issue.
I swear I've read every single post on sls ever written now haha!
The confusing part for me is that it happens when opening the door, which is possibly waking up the slabs?

Tim maybe it's some how switching through to TRANSPORT MODE, this will lower to the bumpstops. You did do a lift in suspension didn't you, did you fit the level arm spacer to raise the height of the ARM on the Lever?
