SOURCE: How to replace front brakes on 2004 BMW 325ci

If it's like most BMW brake rotors you don't remove the center nut to remove the rotor. You should see a slotted screw in the rotor a couple of inches out from the center. Remove it and the rotor comes off. Might have to tap rotor with a rubber mallet but it should come right off.

Location is in the Tank of the car you might want a Pro to do this it is not safe for unexpierianced hands you can get gas in your eyes while serviceing such unless you empty the tank of contence before service you will find the area after you drop the tank to the floor it has various hoses and cable leads disconect them with precaution and note where they are for return in the future also if needed take pictures these will help to reconnect when you are done

Check to be certain that all of the hose clamps are tight and that there are no air or vacuum leaks especially between the throttle body and the MAF (mass air flow meter/sensor)

I hope that this has been of any help to you and will solve your problem.

BMW 325ci - Car cuts off on very hot days - Error code P00128


Check the following :

BMW Code PO128
This means that the engine's PCM detected that the engine has not reached the required temperature level within a specified amount of time after starting the engine. The intent of the P0128 code is to indicate a faulty thermostat. Similar codes: P0125
In determining the engine did not reach a "normal" temperature, it takes into account the length of time the vehicle has been running, the intake air temperature (IAT) sensor reading, the engine coolant

temperature (ECT) sensor reading, and the speed of the vehicle.

You will likely not notice any drivability problems other than the MIL illumination.
A code P0128 may mean that one or more of the following has happened:
  • Low engine coolant level
  • Leaking or stuck open thermostat
  • Faulty cooling fan (running too much)
  • Faulty coolant temperature (ECT) sensor
  • Faulty intake air temperature (IAT) sensor
solutions
Past experience indicates that the most likely solution is to replace the thermostat. Verify coolant strength & level
  • Verify proper cooling fan operation (check if it's running more than it should). Replace if necessary.
  • Verify proper engine coolant temperature (ECT) sensor operation, replace if necessary.
  • Verify proper intake air temperature (IAT) sensor operation, replace if necessary.
  • If the above items check out good, replace the thermostat

AC blows warm air when it rains


It sounds as if you have an ambient temperature sensor that is either shorting out when it gets wet or either the water is acting like an insulator and sends an incorrect reading to the body control module. You may want to contact BMW to the specific location on your particular year and model. As location will vary with model and year.

My 2004 BMW 325 ci convertible is difficult to start.


If the fuel filter has been replaced, then maybe these are other reasons:

1. intake camshaft sensor (known to go bad on BMW E46s). ~$100 part.

2. fuel injectors (though I doubt they go bad that easily). ~$100/ piece. Your car has 6.

3. Ignition coils. ~$90 a piece. Your car has 6.

4. mass air flow sensor. Again, another expensive part. ~$300.
