Bought this car new from the dealer in 1999 and did regular oil changes with the dealership. Just last month .. oil pressure light goes on and discovered that the engine developed a major Sludge problem .... cost $5,000 to fix ...beware! If the dealship knew about this problem they should have suggested to change to synthetic oil and do more regular oil changes ... Terribly disappointed with Audi !!!
