2003 Punto screeching noise at speed

Hello, My 2003 Punto starts to make a screeching noise when driving at speed after about 20 minutes or so. The noise is really high pitched and very loud but seems to stop when feathering the brake pedal (which is
not ideal on a motorway) or lightly turning the steering wheel from side to side (again, not ideal). Please Help!

How's your power-steering fluid level?

Hmmmm
Seem to recall that all Punto's only ever have "Dual Drive TM" electric power steering. Could be wrong (wouldn't be the first time)
Having said this it costs nothing to check under the bonnet so I suggest that this is done

Prior to e-steer (which admittedly, I don't know much about), the pump was drive by a belt. With a low fluid level, at speed, the pump was known to start graunching, which could be corrected by wiggling the steering wheel.
Now I don't know whether this applies to later cars; MK2 and beyond, or whether it could apply to some cars from those ranges, but as you say, it couldn't hurt to have a look.
If nothing comes of it, then hopefully someone else has a suggestion.

so lack of fluid seems to be out of the question here. Like Nick, I also can be wrong but I own my second MkII Punto Sporting now and both do (did) have electric powersteering. I'm not sure, but reading OP's posting I think it could be a sticky (front)brakepad or likewise. I recall one of my Punto's did have this once; steering or (light) braking stopped the squeeking sound for a short time but it wouldn't solve the problem. Cleaning the brakes did. Again, I'm not sure; I'm not a mechanic, just love Italian cars. Ciao, E-Cie

combination with a worn out disk.( disk with grooves). Or a smal pebbel is stuck in the brakepad. I own a 1998 Punto Sporting (Mk I) with an oilpump powersteering. And i'm also not a mechanic, and i also love Italian cars. Vespa Ciao, Nico

If I'm given a chassis number (last eight digists) then I can probably definitively say what the power steering arrangement is.
Year boundairies are too vague. Most manufacturers go on year and week number. One has a 1 in 52 opportunity to get it wrong.
