Most likely, the cause of the unpleasant smell in the BMW 3 E90 is that the heat sink (evaporator) of the air conditioner was contaminated. To clean it, you have to remove the garret, as well as the oven engine, drain the air conditioner from the air conditioner to the air-conditioner, and snub it by spraying the air into the hundredths of the radiator. Then we need to put everything in place and put the baker in the draining mode. The pleasant smell of the freshman will be felt not immediately, but approximately one day after all works have been carried out.
