Had airbag light and n95 igniter 2 code came up. Cleared code and it came back in a week and around 300 miles. Went to audi dealer hoping it was covered by warranty for airbag recall. The dealer checked and charged me $180 diagnosis charge and said $904 + tax to replace clockspring. I replaced the CS, myself with an OEM audi part, cleared the code and it was good for a week. Now I have light on and n95 code again. I double checked the plugs and they are all firmly in. What else can it be?
