Had a bit of a nightmare lately, had the dreaded vibrations and groaning from steering mainly at stationary or slow speeds. Changed the pump with a new genuine one and the symptoms didn’t really improve and now the new pump is whining. Flushed it through loads so no air but noticed tiny metal fragments in the fluid yesterday. So either I’ve been unlucky with the new pump had an issue, or the rack and pinion was at fault all along. Flushed 4 litres of new fluid through the return line with wheels of ground yesterday evening and checked today and still there’s a metallic look to the fluid. Looking at refurbished rack options now as VW want £1800 just for the rack.
