Code P1104 BMW Description
The P1104 code for BMW indicates a problem with the Differential Pressure Sensor Intake Manifold Plausibility. This sensor is responsible for measuring the pressure difference between the intake manifold and the atmosphere. If the sensor detects a discrepancy that is outside of the expected range, it will trigger this diagnostic trouble code (DTC). This issue can have a significant impact on the vehicle's performance as it directly affects the air-fuel mixture entering the engine.
Common Causes of P1104 BMW
- Faulty Differential Pressure Sensor
- Intake manifold leaks
- Wiring or connector issues
- Engine control module malfunction
- Clogged air filter
Symptoms of P1104 BMW
- Reduced engine power
- Poor fuel efficiency
- Engine stalling
- Rough idling
- Check Engine Light illuminated
How to Fix P1104 BMW
- Begin by conducting a thorough inspection of the intake manifold and sensor connections for any visible signs of damage or leaks.
- Test the Differential Pressure Sensor using a multimeter to check for proper voltage and resistance readings.
- Replace the sensor if it is found to be faulty.
- Check and repair any damaged wiring or connectors.
- Clear the DTC code and reset the engine control module to see if the issue has been resolved.
Cost to Fix P1104 BMW
The cost of repairing a Differential Pressure Sensor Intake Manifold Plausibility issue can vary depending on the specific cause of the problem and the cost of parts and labor. On average, the cost of replacing the sensor and addressing any related issues can range from $200 to $500. It's important to note that labor rates at auto repair shops can vary, so it's advisable to get a few quotes from different shops to determine the most cost-effective option.

Frequently Asked Questions about P1104 BMW Code
What does the OBDII code P1104 mean for a BMW?
P1104 indicates an issue with the Differential Pressure Sensor in the intake manifold, suggesting a plausibility problem where sensor readings are inconsistent or outside expected ranges.
What are the common symptoms of the P1104 code on a BMW?
Symptoms may include reduced engine performance, rough idling, increased fuel consumption, and the Check Engine Light being illuminated.
What causes the P1104 code to appear on a BMW?
Common causes include a faulty differential pressure sensor, intake manifold leaks, clogged or dirty sensors, or damaged wiring and connectors.
Can driving with the P1104 code damage my BMW?
While the car may still be drivable, ignoring this code can lead to increased engine wear, reduced fuel efficiency, and potential damage to other components over time.
How can I diagnose the P1104 code on a BMW?
Use an OBDII scanner to confirm the code, inspect the differential pressure sensor for damage, check the intake manifold for leaks, and examine wiring and connectors for corrosion or wear.
What tools are needed to fix the P1104 code on a BMW?
You may need an OBDII scanner, a multimeter, basic hand tools, and potentially replacement parts like a new differential pressure sensor or connectors.
How do I fix the P1104 code on a BMW?
Repairs typically involve replacing the faulty differential pressure sensor, fixing intake manifold leaks, cleaning clogged sensors, or repairing damaged wiring.
How much does it cost to fix the P1104 code on a BMW?
Costs can vary, but replacing a differential pressure sensor may range from $100 to $300, plus labor if performed by a mechanic.
Can a dirty air filter cause the P1104 code on a BMW?
While unlikely, a severely clogged air filter could contribute to abnormal pressure readings in the intake manifold, exacerbating sensor plausibility issues.
Does resetting the Check Engine Light clear the P1104 code permanently?
Resetting the light may clear the code temporarily, but the problem will likely return unless the underlying issue is properly addressed.
