Swmbo has been moaning that her corsa steering feels so light she does not like it , compared to other corsa's she has had .

I used it yesterday for a 40 mile round trip & have to agree that the steering is so light it is verging on dangerous. At 70 mph you can steer with your little finger     It has no feel to it at all . It seems to be very "over responsive" . By that I mean the car moves left or right rather more that you would expect with just minimum movement at the wheel . Recently had an MOT by a guy I have known for years & asked him to really  check  over the steering , as Swmbo was using it, I wanted to be sure it was A1.  All he could find was a slight bit of play in the rack , but it was no where near a failure in his opinion.

I have had a good look around the internet at possible causes , but while there has been problems with this electronic system , cannot find anything that points to what the problem is 

General feeling is that " thats how thay are ".   There is a problem that occurs where the steering powers one way but not the other , but this is fine both ways , albeit that it so very light at all times .

Anyone got any ideas on this or experienced the same ?    any help or advice  would be great. TIA    Al

At a guess i would say there must be a "servotronic" type relay to reduce the power steer flow at increased speeds.

Cannot seem to find anything on the corsa forums I have looked at     but yes I would agree  . . . there must surely be some kind of reduction from standing /parking etc. to cruising at 70 

I will try & get a drive in another of the same spec & year & compare . . ..  as said forums seem to say very light steering is how these cars are

No relays as its all built into the steering ECU

Its assisted by a motor on the steering column, get the tracking checked as if its out badly it can create some really interesting effects, also make sure the tyre inflation pressures are correct and check the tyre condition (look out for crappy second hand M&S tyres !)

Two suggestions.....
Some small cars come with 'bird button' which can be used to make the steering lighter in slow manoeuvres, IIRC the Corsa doesn't.
Another is I've seen Combo van ball joints fitted to a Corsa, one side only. One is straight, the other is dog leg.

I have had a Corsa with weird EPS faults, but not this one. The normal faults are sticky points, wrong centre and more difficult to steer one way or the other.

I know some of the track based VX's retro fit this system and IIRC, there is a speed signal going to it.

Tracking all been done  .  .. was out but only a tad.      Tyre pressures all set correctly . . . front tyres are the ones that came with the car , about 50% worn Pirrelli's   

Really have to try & get a drive in a similar model to compare I think

Have recently changed the bottom joints , track rod ends & drop links . . . . .  but problem was there before that

No it wasn't, you broke it.

Who me STMEO ?   never    bottom joints , track rod ends & drop links changed only because of perished rubbers.

Surely even you know that you should never  use a perished rubber Steve

Perish the thought, Al.

I had a 2005 meriva which, I think, had exactly the same steering as this corsa. Although the steering was a bit light at speed, it definitely wasn't as bad as you describe.

There is a sensor under the steering wheel cowling, normal family is  you get steering that is much lighter in one direction than the other. All I did was remove it and clean it and fit it back into the car. Took a bit of trial and error to get the steering to feel the same both ways but was a success in the end.
Not sure that would work if you're is light both ways, maybe sensor is knackered?
