Air Suspension Relay - Preventative Swap

[jamoca]

Understand from some D3 owners I've spoken with that swapping out the air suspension relay is good preventative maintenance (to avoid the compressor sticking on and burning out) so I'm keen to do it.

From a quick scour the compressor burning out on relay failure does come up - can someone help with which one to replace and how to do?

I've seen 373 and J408 both mentioned (and this thread: http://forum.a8parts.co.uk/showthread.php?t=5085)

Thanks in advance!
