1999 A6 Broken fold down seat lever...
 

Hi,

The lever for the right seats broke when I tried to pull it and I can't get the seat to fold no matter how hard I tried to twist it... does anyone have any idea how much this would cost to fix? Any other tips would be appreciated as well. The left seat folds down fine but I wish the levers were a little stronger.

Try www.vagcat.com for a catalog with pictures and part numbers for the European Audi. The seat should be the same as for the USA/Canada Audi.
Next, either buy a used or new lever for your broken seat.
