Recently went to the local dealership with a AS malfunction. Car steers fine, just a little harder, no real electronic assistance. The dealer quotes me $4500 for a rack and pinion replacement, he determined this by merely hooking it up to the diagnostic computer. Can you really determine this kind of problem electronically?

Has anyone else had to replace their rack and pinion, if so how did they diagnose the problem?

This is (unfortunately) not likely your issue, but it's worth a post. I recently got the AS warning, and immediately felt the manual (unassisted) steering difference. Dealer the next morning, after diagnostics: "Your battery is dying. Non-essentially components (like AS) are the first to fail due to lack of proper charge." Battery replaced. Problem solved.

active steering has 2 backups - one hydrolic (bypassing the planetary gears that make your steering "active") and basic manual (think 1920s). I can't see how the dealer would determine that your primary system is gone by NOT inspecting those gears. I think its "go F^%$ yourself answer. GL

Have you tried resetting the active steering? (wheel all the way to the left then back to neutral)

I guess I need to try the battery first, I'm not trying to be cheap, but $4500 is a little steep. Thanks guys!

AS malfunction lights came on a couple times in the past but cleared themselves, this one has been on for about a month or more. I'm going to disconnect the battery today and see if that works.
