CAN SOMEONE ADVISE.
I HAVE JUST PURCHASED A MERCEDES A160 ELEGANCE SEMI-AUTO WITH PAS (1999)
THE STEERING GRINDS WHEN I TURN THE WHEEL, MORE NOTICEABLE AT LOW SPEED ON RIGHT TURN. THE CAR HAS RECENTLY BEEN SERVICED AND HAS NEW BRAKES, DISCS, TYRES ETC AND HAS FULL SERVICE BY MERC' GARAGES. A SLIGHT KNOCKING NOISE TOO. EVERYTHING SEEMS TO BE IN ORDER, NO LEAKS ETC ON SUSPENSION.?????????

 

Most likely the "anti roll link bar" on either the near side or drivers.

My A-class, year 2000, 75,000 miles, same problem and had to replace them twice...

perhaps the way i drive?
