I also have moved from a 3 series E30 and now an E46 upto an E39.
In the past, BMW NA combined w/ BMW Car Club of America have helped resolve big ticket items such as the instrument cluster pixel issue..
I called BMW NA today and they wanted proof of ownership, which I had to fax to them ???? Does anyone fax anymore ?
In any event based on past postings, even my legacy of owning BMWs since 1988 and an active CCA member may not help ..
We shall see..
