When the "Check Engine" light comes on in the 1997 BMW 328iC, the problem is 99% Emissions Systems. First thing to check are the Four (4) Oxygen Sensors. That is correct your convertible has four O2 sensors. They are about $100 to $118 each, online.
I have done this procedure it is not a big deal. It just requires four sensors. More than likely you and your car experience one or several of the following:
Engine will not accelerate and backfires
Check Engine light is illuminated
Irregular idle during warm-up
Irregular idle with warm engine
Poor engine performance
Fuel consumption is high
Driving performance is weak
The O2 sensors reduce emissions and tells the computer how to mix your gasoline to air mixture going into your engine.
Since you say you have a 328, they have either two or four O2 sensors. The 1997 BMW 328 Convertible has four. Your chassis style is also referred to as a E36 series. Your engine is a 6 cyl M52.
hello, check for a damage crank position sensor this sensor sends the singnal to the dme (digital motor electronics ) to inject fuel and pulse the ing coils and will also start the fuel pump when it see a rpm above 500 this is a good tell sing if you crank the engine and the rpm does not jump there is a good chance that the crank posistion sensor is bad / the battery and engine light will be on untill the engine strarts
