My power steering started making a loud whurring noise when I was turning a 90 degree right turn in low gear.
I took it straight to the garage and when the technician took the cap off the fluid was bubbling.
He said that he'd seen this before and to book it in. He also said that the one before had to have either the steering (rack or the column I can't remember which one) replaced. Although he did advise that the car is still OK to drive just a bit noisy and that I may find the steering a bit heavier at times.
He also said that I may find that the problem just goes away, either way the cars booked in and hopefully all my hitches will be sorted before the warranty runs out.
When I used the car this morning the noise didn't start until about 15 mins of town driving, it is only happening in low gear when turning.
