hey, welcome aboard. I have not seen anyone figure out a way to reset the service indicator on the e90 as a DIY. I think your best bet at this point is to get the bmw dealer to reset it. If you find a way to do it yourself without the need of a bmw dealer, let us know. This would be very good to know those who plan to keep the car beyond the free maintenance and plan to diy oil change and brake. I think it would be difficult to do it outside dealer because its looks like there are several indicators for service (emission, brake, oil, Insp I, Insp II).
