Rated 4 out of 5 stars.
Here's a used WABCO ABS brake ECU for a Land Rover Discovery 2, from about 1998 to 2004.

It's a printed circuit board unit, and the seller says it's been tested and checked with diagnostics to confirm it's working properly before it was removed.

So, it should be good to go.

The part number is SRD000070, and it supersedes to SRD500070.

It's not a modified item, and it's a domestic product.

You get a 30-day warranty with it, just in case.
If you're dealing with ABS issues on your Discovery, this might be the fix you need without buying a brand-new, expensive module.
