I realize this is a stupid question, but a lot of people on here seem to know a lot about this. I have Vishnu’s OBD diagnostic code reader. When I removed my v2, I saw a lot of misfire codes, but with your advice, I realized I had the yellow wires 6 and 7 switched around, and now everything functions normally. Anyway, I can’t seem to get the 300 codes and misfire codes to clear. I tried turning on the car, removing the code reader, and letting the cycle run more than four times, but it didn’t work. The battery was disconnected, but that didn’t help. Do any of you have any recommendations? I appreciate it.

Eventually, the codes will vanish from the OBDII readout if you repeatedly try to clear them. However, they are still present; the OBDII reader can’t see them.

Fault Code Reset

I neglected to plug the air flow meter back in after cleaning my air filter today, thus the engine ran poorly and the Check Engine light illuminated.

When I restarted the car after plugging the AFM back in, it continued to run poorly, as if it were still unplugged.

For fun, I performed the stomp test, and the code returned as 1215, as it should. I was pleased that I could obtain the engine codes.

To get the engine to work properly, I had to reset the light by unplugging the battery and clear the DME’s code.

I found it a little odd that even though the issue had been resolved by reattaching the AFM electronics, the DME kept acting as though it hadn’t.

Does everyone else have similar experiences?

Is there an alternative to unplugging the battery to reset the DME?

I don’t believe there one because the wiring diagram demonstrates that it is connected without a fuse directly to the battery.

If you check Pelican, I think the codes can be cleared by keeping the pedal depressed for 10 seconds after all of the codes have been read. Check out the website; I might be off.

“You may reset the computer and erase every code once you’ve finished reading them. Ensure that the last code (1000) has appeared, then depress the gas pedal for a period of time greater than 10 seconds. The DME’s memory should be cleared as a result. If the fault code reading procedure is repeated, the computer should produce code 1444, which denotes the absence of any errors.”

Your BMW E90’s turn signals can be configured to include the following:

  • Warning lights that flash once or twice
  • frequency of flashing following activation (1,3,5)
  • after the system is informed of a new feature, remove fault codes or change the voltage monitoring
  • Blinkers should flash whether the car is locked or unlocked.

Furthermore, as it improves visibility, we advise turning on the feature that causes the turn signal to blink five times when touched. Additionally, the majority of the features can be independently coded for each key.

What causes a BMW to have faulty adaptive headlights?

The most frequent reason for adaptive headlamp failure is water or condensation inside the headlight because the moisture can harm the adaptive headlight module. If the headlamp does not contain any moisture or condensation, a broken or worn-out component may be to blame for the adaptive headlights’ failure. The potential causes of your adaptive headlights failing and malfunctioning include the following:

  • Broken or cracked headlight: If water enters the headlight of your car, it could harm the adaptive headlight module.
  • Damaged or improperly closed headlight access door: The headlight access door has a seal that keeps moisture and water out of the headlamp. It is possible for water to enter the headlamp and harm the adaptive headlight module if the seal is broken or the access door is not closed completely.
  • Malfunctioning Adaptable Stepper Motor: The adaptive stepper motor, which is also housed in the headlamp, rotates the light projector to the left or right. The projector cannot be turned if the motor is damaged or the connection between the motor and the projector breaks down.
  • Failed Adaptive Headlight Module/Stepper Motor Controller: Water may enter the headlight when you drive through a car wash, flood, or a lot of rain. The adaptive headlight module, also known as the stepper motor controller, is found near the bottom of the headlamp, where the water will flow straight downward. The module will then be damaged and shortened by the water.

Is BMW check engine the same as service engine soon?

1. Let the car warm up after starting it.

2. Activate your headlights.

3. Fully depress the accelerator pedal and hold it there for 10 seconds.

4. Let go of the gas and switch off the headlights.

5. Permit the vehicle to idle for a while.

Does removing the battery reset the ECU?

A. The age and kind of the car’s ECU are key factors. Disconnecting the battery may reset the system in some older vehicles, but in the majority of modern vehicles, it usually has no effect other than possibly resetting the clock and radio station presets.

In a contemporary car, if you accelerate quickly, the ECU will automatically regulate the air temperature, engine temperature, and fuel usage to the best of its ability based on the driving conditions.

For auto gearboxes, certain ECUs offer “adaptive learn” capabilities. They can modify the points at which they shift gears and sharpen throttle reactions if they notice a pattern of aggressive driving.

What does a malfunctioning adaptive headlight mean?

Under the headlight housing is where you’ll find the adaptive headlight module. It is also known as the Adaptive Headlight Drive Control Unit Lighting Module or the less catchy Stepper Motor Controller (SMC) (ALC). Water is the primary reason the adaptive headlamp module fails. This may occur for a variety of causes, including driving through flooding or severe rain or going through a car wash. Your BMW’s dashboard will thereafter show the adaptive malfunction error message when this occurs.
