Does anyone know if the instrument cluster for an 2001 S4 will work on a 2000 A4? they have the same form and gauges, and screen . I am thinking more on the connectors....

I think they will swap over but im not 100%

depends on the immobilizer system. I think the 2001 has it..and the 2000 does not. See the tech section of audiworld.com for related info.
