Correct Parts Can Prevent Costly Repairs

Is your “Check Engine” light on with BMW codes 2882 or 2883? The OBDII (on-board diagnostics version 2) generic codes are P0171 P0174. Don’t let other shops mistakenly replace your Air Mass Meter or MAF Sensor (Mass Air Flow) costing you hundreds! Your most likely problem is an incompatible air filter. The proper air filter for your car is supposed to have a foam backing that directs air through the system properly.
