I've torn my dash apart looking for it, I thought it was under the left dash panel (under the steering wheel) but it's not there, I've seen other sources saying it's under the seat. Does anyone have any input?

J403 is the Relay. I should be mark 373.

if you are looking for the air suspension solenoid valve block. that is located behind the driver wheel lining, under the driver fender.

AAAGGH!! I just put all that back together, tried 2 out of 3 relays, I'm an idiot and thank you very much for helpin me out!

Relay doesn't fit ordered a new one, 40A fuse blown too, plugged in new one setting reappeared then went all blank.

Sounds like the compressor is drawing too much current. Those wacky WABCO electric air compressors. Usual failure mode is one of the magnets that is glued to the inside of the motor tube breaks away causing drag and high current draw. Proper procedure is to replace the compressor. However, taking the m otor apart and JB Welding the magnets is the cheaper alternative.

I just ordered an arnott replacement for $379 which i think is a pretty damn good price, probably going to swap it out myself, it doesn't intimidate me too much, and it says it comes with very detailed instructions so I should be good to go. I will look into welding the magnets like you said and maybe keep a spare even though the arnott unit comes with a 1 year warranty.

Oh also, the compressor had a sickly sweet smell to it whenever it engaged, then started making a HORRIBLE noise, then blew the second fuse I put in.

I contacted Arnott today and they told me that they don't sell the A8 replacement compressor. Did you buy the AllRoad one? It's the same unit isnt it?
