i just got some of the newest hitachi coils straight from audi and since i put them in they work amazing. I went through six or seven coils previously and I had so many strange backfiring problems you would not even believe. if it is not that little thing you broke try and check out these coils. They say Hitachi on them and i'm pretty sure they are the hitachi "e" coils but what i did was have my dealer/mechanic call audi and apparently they only sell them per VIN number but they refunded my money for the bad parts. i also took off my engine cover for less heat. good luck
