2007 BMW 328i Sedan - Answered Questions & Fixed issues

One of the bulbs is not working. Check and fix.

If it has an electric pump you should hear or see water flowing when car is turned on. If not, check any fuses or relays for the pump, and there is probably temp sensor controlling the pump. The main thing is to make sure any fuses and relays are working before tearing the pump out.

check the blower motor resister. This protects the fans and blower motor. Before fans come on the thermostat has to open at 192 degrees

why the fault codes were not read is the question to ask it could be faulty injector/s position sensor or ignition module all of which would show up as a fault code. have the codes read before you waste any more cash

Is it a high pitched noise you are asking about..?? Probably a fan belt slipping.. Or is it burning oil That concerns you?? Or is it fuel getting into the oil that concerns you ?? 328I.. does it have the 6 cyl engine? one of the most dependable and long lived engines ever made..

Hi CadeYou are driving a possiable dangerous car as you have said Hazzardous yes, if it stopped on you and your on the Hiway you may have an accident.Therefore my opinion is it maybe your computer, crank and cam sensors, 02 sensors you may have 3 or more, your throttle position sensor or switch, your gas filters, dirty airfilters dealer can read codes and trouble shoot more precise BMW nice car needs maintence. You dont want to take any chances but you can try replacing airfilter gas filter is a good start.JOE

pinched wire..

If its not holding as charge your battery just cvoincidently went bad

If test gauges were hooked up to it after the light went ON then there may be a Diagnostic Code to identify the Electric water pump as the problem. Check out the AboutAutomobile.com site for any consumer complaints about your Brand and Year of car. If there is no info there, it is not a freqent problem. But if it is listed, so are Resolutions. Another site which may help, if they list your Foreigncar, is Autozone.com. You register your car for free and then access the wiring diagrams and the Fusebox and Relay Layouts. You may simple have a bad Electric water pump Relay. The Relay is triggered by a Temperature sensor. Often there are 2 sensors with the other operating the dash gauge. Just unplug the suspected sensor to see if it controls the dash gauge and once identified, replace the correct sensor. Another area is the Cooling Fan. You should have a Engine cooling fan around the Radiator. This works with temperature and Relays. Sometimes the fan has 2 speeds and one can lose the high speed or booster fan settings. The Fusebox and wiring Diagrams will help to identify these parts.If your trouble lamp is on, sometimes Scanners at Autozone, Advance, or Oreilys can identify the problem. It is FREE to scan at these stores.I hope my solution is helpful.

The check engine light issue could be a faulty dash bulb or consul. It looks like you could do worse than get your car checked out on a diagnostic consul.Failing that, emissions failure is usually a fault of the engine not running at optimum. Is the air filter clean, air temperature sensors clean. Finally take it out for a good run to burn of any residues before checking emissions.

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.
