Fault codes 4D02 and 4804 are related to the urea pump under the rear of the car. The pump was not building up pressure. You have to drop the exhaust to get to the pump above the tanks. 6 hours of labor plus 300 ish for parts if you have this done out of warranty at a BWM dealer.

I'm praying for a service manual to be written for this car.
