2003 BMW M3 Problems
A fluid leak may develop from one or more power steering hose. When a leak is being repaired, it is not uncommon for multiple hoses to be replaced.
During tight, slow speed turning, a rubbing noise can sometimes be heard from the rear of the car. This noise is likely coming from the clutches in the limited slip differential. If the noise persists, the differential fluid can be replaced with a special oil available from BMW. On higher mileage vehicles, this noise may never be eliminated unless the differential is replaced.
The blower final stage fan resistor is known to fail. Symptoms are the heater fan speed varies regardless of the setting, the fan will not turn off when the car is switched off, or the fan will not switch on at all.

2003 BMW M3 Recalls
Upon deployment the passenger airbag inflator could rupture, increasing the risk of personal injury. BMW dealers will replace the affected airbag inflator modules to correct this concern.
Airbags use a chemical reaction contained in an inflator module to create the pressure necessary to inflate the bags when deployment is required. These vehicles are being recalled because the front passenger airbag inflator may produce excessive internal pressure when deployed. As a result, the inflator module could rupture, causing metal fragments to strike vehicle occupants. Dealers will inspect and replace any defective passenger front airbag inflator modules found.
The anti-pinching feature for the power windows may not function properly. A person may be pinched by a window being closed. Dealers will inspect the electronic control unit for the window lifting anti-pinching device, and replace it if necessary. The recall began May 27, 2003.
