Does anyone know what causes this issue of a pull on the wheel when the steering is on half to full lock, it feels as if the power steering is trying to straighten up and happens as a series of rapid regular jolts to the steering wheel. I have seen other Berlingo owners posting about this issue but there seems to be no definitive answer, my local Citroen dealer has never heard of it. I have had a r/h drive shaft and the ram replaced. Thanks.
