Code P1592 Audi Description
The P1592 Audi code refers to a problem with the Barometric Pressure Sensor or Manifold Absolute Pressure Sensor in the vehicle. These sensors are crucial components of the engine control system, responsible for measuring the atmospheric pressure or the pressure in the intake manifold, respectively. The code indicates that the ratio between these two pressure readings is implausible, which can lead to a variety of performance issues in the vehicle.
Common Causes of P1592 Audi
- Faulty Barometric Pressure Sensor
- Faulty Manifold Absolute Pressure Sensor
- Wiring or connector issues
- Vacuum leaks in the intake system
- ECM malfunction
Symptoms of P1592 Audi
- Decreased fuel efficiency
- Rough idling or engine misfires
- Hesitation or lack of power during acceleration
- Engine stalling or rough running
- Check Engine Light illuminated on the dashboard
How to Fix P1592 Audi
- Begin by connecting a diagnostic scanner to the vehicle's OBD-II port to retrieve the specific fault code and confirm the issue.
- Inspect the Barometric Pressure Sensor and Manifold Absolute Pressure Sensor for any signs of damage or corrosion. Replace any faulty sensors.
- Check the wiring and connectors associated with the sensors for any breaks or shorts. Repair or replace as necessary.
- Inspect the intake system for any vacuum leaks that could be affecting pressure readings. Repair or replace damaged components.
- Clear the fault code from the ECM's memory and perform a test drive to ensure the issue has been resolved.
Cost to Fix P1592 Audi
The typical repair costs for addressing a P1592 Audi code can vary depending on the specific cause of the issue.

Frequently Asked Questions about P1592 Audi Code
What does the OBDII code P1592 mean for an Audi?
P1592 indicates an implausible ratio between the Barometric Pressure Sensor (BPS) and the Manifold Absolute Pressure (MAP) Sensor, meaning the two sensors are reporting conflicting data.
What are the symptoms of code P1592 in an Audi?
Symptoms may include reduced engine performance, poor fuel economy, hesitation during acceleration, and illumination of the check engine light.
What causes the P1592 code to appear?
Common causes include a faulty MAP sensor, a malfunctioning barometric pressure sensor, wiring or connection issues, or even a problem with the engine control module (ECM).
Can a dirty air filter trigger the P1592 code?
While unlikely, a severely clogged air filter could indirectly affect air pressure readings, but the code is typically caused by sensor or wiring issues.
How can I diagnose the P1592 code?
Check the MAP and barometric pressure sensor readings using a scan tool, inspect wiring and connectors for damage, and verify that the sensors are functioning within their specified ranges.
Is it safe to drive with the P1592 code present?
Driving with this code is not recommended, as it can lead to poor performance, reduced fuel efficiency, and potential damage to other engine components.
How do I fix the P1592 code on an Audi?
Repairs may include replacing the MAP sensor or barometric pressure sensor, repairing damaged wiring, or reprogramming the ECM if necessary.
Can a vacuum leak cause the P1592 code?
A vacuum leak is not a direct cause of this code but could affect MAP sensor readings and lead to related issues.
Will clearing the code with a scan tool fix the problem?
Clearing the code will remove it temporarily, but if the underlying issue isn’t resolved, the code will likely return.
How much does it cost to repair the P1592 code?
Repair costs vary depending on the cause but can range from $100 to $300 for sensor replacement, plus any additional diagnostic fees.
