A160 ELEGANCE 1999. GRINDY STEERING
 

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.?????????
