I have 1200 mi service coming up tomorrow on an 03. Several electricals to fix. Any other things to have dealer address? I have some concern about slow 1-2 upshift on SMG.

try making a few tight left and right turns to see if your differential makes any noises.

what electricals need fixin??

Depends on build. 09/02 and later have a new diff that fixes that.

Older cars can get a new diff fluid. TS 31-01-02 IIRC.

Make sure your engine hasn't blown up.:D;)

Kevlar: Can you elaborate?

I have about 1700 miles and when I make tight turns i hear a "rubbing" sound, but I'm too sure what it is. It is intermittent though and I hear it mostly making tight left turns..
:help

Some cars exhibt that rubbing noise. I haven't taken mine to the dealer yet cause I'm too busy driving the car. Dealer is supposed to know how to fix it.

I've only heard it on my car once. I solved the problem by not making tight turns.

This this a serious problem? Will it get worse? Or should I get it to the dealership asap?

It's not really a problem, it's by design of the limited slip diff... however, the noise part is the part that needs to be fixed. I haven't taken my car it yet... and it's still running, so the problem can't be that bad.

The noise is a retcheting popping noise wile making tight slow turns, it's a perfectly normal noise from a clutch type diff and not a sign of any problem. The noise should lesson as the diff breaks in. BMW has a diff oil with greater amout of slip modifier in it to quiet noiseier diffs. Current production cars are not affected, earlier cars were.
