Yes. The power steering shuts off if there is insufficient electrical power - so I think once you've fixed the alternator, the power steering will be fine - good news indeed.

:yeahthat: as battery isn't powerful enough to run the EPS, if alternator fails then steering is deactivated also

Happened to me on a VW Passat I used to own. When I had full lock on, it made an awful grinding noise. Replaced the power steering pump, all the belts, cost me a fortune. Eventually traced it to a failing alternator. It wasn't generating enough power, which caused the power steering pump to be under powered.

You can also check you battery voltage. If everything ok you should get over 14 with engine running, and about 12.8 engine off.
