I would be interested too, is the access to relays easy or is it a take half the dash out job?

Thanks Matty.

I found this thread on another forum (no lynching please!): https://www.audiworld.com/forums/a8-...-fuse-2835590/

Not sure I'll get round to this for a couple of weeks but I will take pictures and do a thread - this one's probably a candidate for a sticky.

Daft question for ordering - will any genuine Audi 373 relay work or is there a specific one for the air suspension? Do I just say J403? Reason I ask is because I see 373 relays are used for other things, e.g. gas discharge bulbs.

Thanks again

Yeah any 373 relay will work. 373 is the relay type, in this case it's a 'make & break relay normal open with coil suppression resistor rated at 12v 40amp'. They are used elsewhere, hence giving it the name J403 to identify it as the air compressor relay.

It does have a VW/Audi part number: 8D0951253A
