(G) Active Sport Steering gone really light.. power steering problem?

Hi,
I would like a little help and advice on this problem i have noticed yesterday.
I appears that something is different with the power steering, it is much lighter than normal and the city mode is not on.
It is almost as light as city mode, but doesnt have the same feeling etc.
I have tried turning city mode on and off to try and fix it but it still is doing it.

Punto is a 2003 active sport 37000 miles.

Any help appreciated.
thanks

37k have you just had a 36k service by any chance may have blown your tyres up a bit

other reasons may have faulty torque position sensors in the column

nether heard anything like it myself

does your city button make it lighter still or stay the same

Yep has 36k Service.
City mode makes the steering lights, like allows the wheel to turn all the ay round easier, how ever with city mode off it seems it only goes light once driving.

it's likely your tyres have been blown up on that service then making it lighter
