Last few weeks the rear sagging again over 3 days and onto the stops.
Replaced the Compressor, thinking that i had valve block problems.
3 days later sagging to the stops.

Nanocom showed a significant discrepancy between L and R sensors.
L sensor at 149 and R at 132. with the car level.
Levelled the vehicle at ride height and stored the new settings.
L at 149 and R at 149.

3 Days later down in the butt again. Sensor readings within 2 of each other but still sagging.

Swapped original compressor assy, same problem.

Nanocom readings for both sensors @ 4.99v (good according to RAVE)
Voltage to L and R solenoid valves 0.00 when not energised (again good)

I now have a brand bew compressor assy and a pefectly good original assy. New bags and a saggy butt!!!!
Done a spray around the bags and cant see anything.

What have I missed!!!

Should I pull the bags and test them out of the car?

Cheers

First thing to do IMHO, is park on level ground, either hook up a trailer OR load back of vehicle with at least 100 to 150kg and THEN spray detergent all around bags, especially at the bottom where they fold under. Even new bags can get damaged/ develop leaks.

JC

and sell me the used compressor cheap so i can see if i can get them sleeved. see if we cant get a reasonable priced option on replacing these things.

Problem found.
Both Air Bags are leaking from around the top retaining ring.!! Plenty of weight in the back and raised it up high. Bingo.

Arnott Ind, will be sending 2 new ones (I doubt I'll see them until new year)

Happy to find the problem, but dissappointed in the product. One giving up I can accept as bad luck, but 2....This is a manufacturing fault. After the run my boy has had with his American "quality" tyres, I really hope this is just an unfortunate batch issue and not a recurring theme.

I feel a little dumb for not thouroughly checking the bags before buying a new compresor assy. Assumption of new items doesnt cut it always.
At least the whole show is new.
Also proves that the consistent theme for SLS probs. is predominantly the bags

So I'll be keeping the new compressor fitted and putting the old one on flea bay.
I have scored the spring seats for a conversion to coils, so if I have any further issues..........maybe the SLS will go.

Cheers
