Code 01780
Hi there
Audi q7 4l diesel 2007
Code 01780 mechanical malfunction. Sensor for vehicle leveling

Is this the valve block where all airlines connects to?

It's much better if you provide all the error message coding received from the full diagnostic scan, as you will often see numerous error codes linked together, or seemingly unrelated error codes when air suspension is having a problem. Also useful is what have you done prior, if anything, to maintain the air suspension system? Car history/mileage data, etc. The more data you provide the easier it is to assist you remotely.
A quick search for error code 01780 and your car's year/model indicates it is most likely the height sensor/leveling sensor on one corner is failing or broken already. The linkage pivots on those will eventually fail, or the sensor itself; a completely normal occurrence. If you've got VCDS or similar VAGCOM scan tool, you can view the live data from the height sensors to see which one(s) are having issues. You can also inspect the level sensors directly, which may allow you to visually identify if one is mechanically broken, or frozen in place, etc. Notice the "mechanical malfunction" description you included with the error code above.
Suggest you verify condition of all the level sensors while you are at it.
