jaguar xf sportsbrake 2013 suspension air warning light comes on any ideas

 

When does it come on? (e.g. every time once you accelerate to above 30mph - in which case it's probably the compressor - see https://www.jaginfo.org/posts/2843843/ )
I suggest you read the fault codes with something that reads full length codes from all modules e.g. Autel AP-200
