Hi Peter I suspect the symptoms are when you first drive the car the steering shudders quite a bit especially when close to full lock or low speed manoeuvring after a time once the car is warm and the tyres are warmer the symptoms reduce or disappear. When I researched this it became clear that the issue was the tyres and Pirelli tyres as good as they may be in other aspects, suffer badly with the shuddering problem in cold weather. The only solution I am afraid is to use different tyres with an inherently softer make up. I swapped my tyres (Pirrelli P Zero) for a midling quality brand and it has solved the problem. Of course make sure there is no other underlying issue. Hope this helps
