having a wee issue with the power steering in my 170.
Only really notice it when I leave work, where I park on a slight hill, nose facing down the hill. When I turn the wheel lock to lock (as some manoeuvring is required sometimes) it is like the power steering is working intermittently, kind of like a digital on-off. So lock to lock the steering can go, stiff-soft-stiff-soft, 2 or 3 times.
Also so noticed it this morning when pulling Into said car park, car now facing up the hill.
like I say this is the only time I have noticed it, and apologies about the rubbish explanation.
Has as anyone experienced anything similar?
