pipes, compressor, bags, fuse and a relay!

[onetwentie]

Hi all

I have a very quick question after having read quite a few threads on here regarding troubleshooting a leak in the air suspension system.

where are the frikkin pipes??

I am trying to troubleshoot this issue with my 2007 3.0 TDI A8 and have thus far managed to establish:

the 40 amp fuse in the passenger footwell is fine
I have changed the relay in case

please help.

Also is it true that if I want to test the compressor/pump I can do so from the relay location by giving it live and ground to the correct terminals?

thanks all in advance.
