Hopefully i can help..
First off you'll need to check the actual fluid level currently in the power steering reservoir just to be sure the level hasnt dropped again..often if the level is left to drop or the ps fluid was left to run dry this can have a knock on effect with the pump internally..thus it will either clatter or whine as you describe when the engines running..I wouldnt say it would be something to ignore as the pump is the primary component to ensure your power steering works..the only option really is to replace the pump itself..this can be either done with new one or as most people generally opt for a secondhand unit from either a breakers yard or online such as ebay etc..If they have diagnosed the source or the noise from the pump then im afraid the only way to remedy the fault is to replace the pump..I do hope this helps..If you need to ask anything else or include anything further then just continue before you rate
Thanks for your help. The fluid is at correct level, but still making the noise when stationary. The sound appears to be coming from the belt area.
Hi..there thanks for your responce..
If the noise appears to be from the pump which is part of your reservior too..which you note has the red steering wheel sticker on it..thenits likely the pump has suffered some sort of damage internally due to loss of fluid from the previous issue..this is all based on the the fact the nopise wasnt there before hand and has started just after this fault..An easy way to tell is to remove the belt you had put on that runs the pump and the start the engine up..if the noise has stopped then you'll know its one of the assesories driven off that belt that the cause for your problem..it may not be the pump..could be either the alternator/belt tensioner/air con compressor if fitted..its really a case of listening and narrowing down the source of the nosie something you may want to check yourself if prefered..I do hope this helps further..
