Steering Rod Relay Connection problems of the 2000 Audi A6

I had been complaining to Audi service about a noise in the steering. This was reported to them in may of 2002. 43,769 miles. I was told no problem found. I brought this to their attention again in June of 2002. 48,743. No problem found. In Jan. 2003 I brought this to their attention again. They had to replace the tie rods. I was told at this point due to the mileage on my car I had to pay for repairs. In doing further research, I discovered the 1999 Audi A6 had a recall for tie rods. I feel this matter of the tie rods for the 2000 A6 Audi should be looked into.
