L322 C1130-66: Air Spring Air Supply

[this_is_anarchie]

Hi everyone.

I have a 2007 TDV8 and occasionally after a bit of driving i get a "suspension fault" notification. Code coming up shows on reader as "C1130-66: Air Spring Air Supply. - Signal has too many transitions/events". When left for a good-ish period of time (overnight) the rear seems to have dropped, but raises up without issue and all heights work. I don't think (or hope) that it is air bag related as both rears are dropping, and two going at the same time seems unlikely?
Any ideas, or what i should do first?

Here any help, weak compressor has it ever been done?
If its dropping overnight then check for leaks first, its cheap and easy to check.

I don't know if its been done, I haven't had the car long. Also do you have the rest of that document it seems really useful?
Thanks

I do have the file yes but not sure of its size, so only tend to post a relevant page for help.
I signed up to topix and paid for it then downloaded the whole lot still sorting it out into named files for myself. Took a weekend to get them all but worth it.

If the rear is dropping, check the air springs for leaks with a soapy water spray. A leak would account for the compressor operating too often.
