My local dealer is selling 2 S1's. 350.00..they were ordered for the new 05's but there is some new battery light comming on. I think they just thought they could put in the 04' S1 into the 05'. So now my question is, can I put this S1 in my 04'? Or do they have to reflash it? They said it's all BS and it will work in my car. I'm thinking but it. I'll have it in my hand and not have to wait 5-6 weeks.
