New compressor..suspension still inactive?

[Summiitt]

I've just fitted a brand new air compressor to my 04 rangie, before I fitted it I had the air susp inactive up on the dash, and the 2 lights on the control dial, now I have no lights on the control dial and the error msg still on..I fitted a new relay as it's recommended to do so with a new compressor..I'm wondering if I need to get the car plugged in and the codes reset or does the computer need to be matched to the new compressor?

Very probably.

Yes, faults need to be cleared.

Message centre in the dash should tell you what faults are still active.
Then you need a reset.
