Replacing Suspension Control Module

Replacing Suspension Control Module
I have a 2007 S8 with the suspension amber warning light on. Checked wiring, relays, and fuses. Mechanic wants to try replacing the Suspension Control Module.
Has anybody done this? Does it require any reprogramming? I purchased a used one from Ebay.

Yep.
I've never heard of a suspension control module going bad and I've seen a LOT of AutoScans.
More importantly I had a heck of a time finding that P/N, but don't have access to PartsLink24 at the moment.
It needs to be matched by VIN to the vehicle as their are different firmware versions.
But it's not that module anyway - 99% certainty, but a complete scan will tell all.

Diagnstic software will tell you the likely issue. If the WABCO electric air compressor is original, it is the likely culprit. However, a diagnostic scan is mandatory for troubleshooting.

My mechanic has been doing scans and recommended the replacement. I should ask for a copy of the codes next time and post it here. When I called the dealer for the part# they gave me was 4E0910553L the one I bought used on ebay is 4E0910553H
I assume the last letter is the FW versions. So should I even try the install or just return it? A new one from the dealer is $1000. At that price I might just convert the whole suspension system to coilovers. Anyone actually done a conversion before?

Similar issue with my 2008 Audi A8L. Audi ran diags for me and found the ride suspension control module was showing different errors when the compressor and the switches were reading fine. The car would tilt and Audi said it was the control module not being able to identify how it was riding to make the changes. I've got a used one on order, to try it in my 2004 A8L, then will try to get my 2008 module rebuilt in by ModuleMaster.com as the current plan.

I don't remember the error code but my '05 had a code for the suspension control module when i bought it. Changed it out with a used one from ebay and it fixed it. The key is making sure the error is the module. It's not a common failure item.
