Hi. Need advice if possible. My V reg Galaxy 1.9TDi has just developed a strange fault. In dry conditions it is fine but when the road surface is wet and I turn into a sharp corner at any speed, the power steering seems to go off until I straighten up again. Only off for a couple of seconds at most. This makes the steering very heavy and its is quite off-putting to say the least. I have had no recent repairs on the steering or suspension. MOTpassed about 3 months ago. Any ideas? Ta
