take the bulb back out and clean inside the bulb holder, there may be some corrosion or other debris in there

dimmer switch is on the dash on your r/s and must be replaced

If you took this in and had BMW do the work to fix it and it is not fixed why do you not return to BMW and get it fixed, If you have paid for a repair and the repair did not solve the problem have them refund your money.
