What relay is for the air suspension pump? I have a 2001 Audi Allroad 2.7T I took the 373 one out but im not sure if its the right one. I am not sure how to test it because you have to have power to it to flip the switch inside. I took the pump because it was starting and tested the pump it is working turned on so now I am thinking its a relay?

the 40A orange fuse is good, I dont have VAG-Com atleast yet just lost my job so I am trying to go the cheapest route, is it possible to use a paper clip in the plug to bridge connection to see if pump turns on?

The Allroad has 150,000 miles the wheels are all in the wheel well so the car is not movable this is because it was sitting for so long, please help ASAP because I am working on this right now would be gladly appreciated THANKS

Another thing can I use a tire air compressor to fill up the suspension as a temp

 

TESTED 373 and it is good any thoughts?

 

Just for reference the relay is found under the steering wheel in the 8 point relay carrier, relay J406, in position 6, i think your issue is the N111 valve or the wiring to it.
