2009 BMW 328i Convertible - Answered Questions & Fixed issues

some a/c will not work unless the blower fan is also on check for power to the compressor clutch when all is on. There is a pressure switch at the receiver dryier That little round black cylinder next to the condensor in front of the radiator It is used to stop the compressor if there is too much pressure or not enough gas. If it is working then the system needs looking at if not there will be no power when the a/c is switched on

Contact your dealer you usually have to pay for it.

My guess would be to look at the secondary air pump, they are often the failure point for this error code... take some time to look at the pump (front passenger side of engine) look for cracked lines... check for power before you replace.

The pedal position sensor is placed by the acceleration pedal under the dashboard if it is left hand driven where your left foot accelerates and if it is right hand driven where your right foot accelerates.

well a good place to start is buying a repair manual and a gasket.

bank 2 sensor 1 is a heated oxygen sensor in the manifold or exhaust before the cat converter it is not an o2 sensor which is oxygen sensor after the cat converter for bank 2 two completely different sensors the fuel trim code appears because of the problem sensors the fuel trim is cpu program in the computer in the ECM setting a optimum fuel /air ratio after a period of driving if the sensors both HO2s and O2 sensors are faulty then the cpu cannot set the fuel trim

Don't rely on web info for this--buy a cheap shop manual.

see radio repair shop it might be a condenser

The battery is dead

Hi Vlad This sounds like fuel pump problem, or maybe even a fuel blockage in the filter, as what might be happening is when you trun over the car a small amount of fuel is getting through and then running out quickly and not keeping it running, so either the fuel pump has an intermittent fault and only runs for a short time and stops, or your fuel filter may be blocked and needs replacing, to find out if your fuel pump is ok, turn the key so the lights come on on dash but dont run it, go to the rear of the car and listen to see if you can hear a humming noise, what might be better to do is get someone to be at the back to listen as you turn the key, or get someone to turn the key while you listen, if you hear the pump hum, then that will be ok and then you might have to change the fuel filter. this is what it could be, however there may be other things involved, but that would be a good place to start. Hope that helps
