On these the power steering is electro/hydraulic and will only work if the battery charging system is in order.Sounds like you may have an alternator fault.Cost will vary depending on unit supplier.Get a quote from Vauxhall first.Some of their exchange units can be competitively priced.hth

Vauxhall Astra G Diesel 1.7CDTi Van 2004 - Alternator and power steering failure - steps

I had exact same problem, i was driving along no problems, then i veared left then right to avoid some potholes. Seconds later, my battery light lit up, car was still running ok, but i had no power steering. My first thought was the supply from the alternator to power steering unit. Checked the plug, the one with single blue wire. That was fine.Managed to get home. I knew that the alternator was okay, it was a new one. The problem in fact turned out to be extreme low level fluid in the power steering reservouir. Topped up and all is fine now. Light off and power steering okay. I can only assume when i veared rapidly i actuated some kind of cut off to power steering.Been fine since.

Normally when the alternators go on the Astras it's just one little diode in the rectifier bridge that needs replacing. You could identify and replace it for about 20p, or replace the full rectifier bridge for about £20. You need to take the alternator apart and solder the new bridge in but it does make sense, as the alternatives are to get a dodgy reconditioned one for about £80 or pay Vauxhall about £200.
