Adaptive air suspension problem

[sweAudiQ7]

Hello, i recently bought an Audi Q7 from 2008 and i have this weird problem with the air suspension…

The air suspension light Will most of the time come on but not always, maybe 95% of the time its blinking but sometime it dosen’t show neither any problems with selecting which height, i ran an OBD fault code today but no fault code at all came on. 
 

Thanks in advance

Could be anything. Not all OBD readers are the same. Needs a full VCDS scan. Could even be battery related.

I removed black battery cable and charged it to make sure its not battery

Hello Daniel,

Charging the battery to prove it is serviceable is really meaningless. You need to get its efficiency measured over the important parameters, before you can eliminate it as being a contributor to your issue.

Kind regards,

Gareth.
