how many o2 sensors are on a 328?

[1st Beemer]

I am wondering how many o2 sensors are on my car, and if this is what is causing my " secondary air flow too low " code to come on,

[007ben]

what year is your car?

I belive 95(if not 95 then it is definatly 96) and later are obc2 which would most likely mean 2. before than should be 1....

I could be wrong though I only kinda know what I am talking about. If I am worng i will be corrected I'm sure.

It is correct. 96+ = obd2 = 2 O2 sensors.

previous years 92-95 had 1 O2 sensor for the M50 motor i believe.

95 M3 had the obd2 right?

OBD II is 96 and ABOVE. That means 95 M3 is OBDI not OBDII. Also, 96 and above M3 with OBDII have 3.2 liter retricitive engine. 95 M3 has OBDI 3.0 Liter engine.
