My '99 A6 Quattro has just failed its MOT because the offside (RHS) steering rack boot is split. Anybody got any experience of solving this problem? Is it something I can do myself? I called my local independent who groaned and said it wasn't a nice job, but he hasn't rung back with his estimate yet. I don't mind tackling it myself if it's just a spanners-and-logic job, but can't find any how-tos on the Interweb.
