AUDI A4 TDi, 1999
The red light of the Air Bag, in the front panel, is turning ON.
They fix it, but 2 or 3 days after, it is back ON again.
I was told that it is an electric plastic piece, under the front seat, that doesn't work OK (no contact, sometimes).
Audi (in Algarve/ Portugal) says that to fix this problem, they need to replace ALL the air bag electric system as they don't change, just that litlle elecrit plastic piece (and that will cost me about 1.800 euros)
As this doesn´t make sense to me, I would like to have your opinion and the ADRESS OF AUDI, in Germany, if you feel that a letter to them could help.
Thanks.
