So I have had a problem with the left rear indicator. Replaced the bulb which now works 10 percent of the time.
Driving in sport mode (always) I noticed I lost power every time I put the left turn indicator on.
It feels like I drop a cylinder (noticeable but not catastrophic.)
After a bit of fiddling it appears to be dropping out of sport mode when I turn on the signal. (Doesn't make any difference in power if I use indicator in non-sport mode.)
Any thoughts on a fix? I can't imagine there's any connection at all between sport mode and indicator electronics but ...
Thanks.

Don't tell this story to a non-Bmw owner otherwise they're gonna be quick to make that infamous joke about turn signals lol.
I don't know how they could be related, but the fact that it doesn't work well despite changing the bulb sounds like a faulty relay to me, since my car has the same issue (but nothing power related, non-M E46's don't have a sport mode anyway).
