Help! Vibration on steering wheel when turning

[BERLINGO 2L HDI]

Hy Everyone, can u help?!
2012 Berlingo, 50,000 miles. When i turn wheels, particularly at slower speeds there is a vibration coming up the sterring wheel from fromt wheels. Garage told me today, they think its the power assisted steering pump. What do you think? Please give me some ideas, I'm a lady driver and dont know much about cars!!

Quite possible they are right,

you could always get a second opinion

If thats all its doing i would not worry too much.
