Understanding the P1604 / 18012 Error Code: What it Means

If you’re experiencing issues with your car and have encountered the P1604 / 18012 error code, you may be wondering what’s going wrong with your vehicle. These error codes, often associated with the DQ250 transmission control module, point to an internal fault in the output driver IC. In simple terms, this means there is an issue within the control module that’s preventing it from performing as expected.

What Does the P1604 / 18012 Error Code Mean?

The P1604 (also known as 18012) error code is a common diagnostic trouble code (DTC) related to the DQ250 dual-clutch transmission found in many Volkswagen, Audi, and other VAG group vehicles. It indicates a problem with the internal control module, specifically within the output driver IC (Integrated Circuit). This error suggests that the control module is unable to communicate or send the correct signals to other components of the transmission, which can lead to drivability issues.

Symptoms of this fault may include:

• Harsh or delayed shifting.

• Erratic gear changes.

• Transmission slipping.

• Increased fuel consumption.

When left unaddressed, this error can result in more serious transmission damage, which can be costly to repair.

What Causes the P1604 / 18012 Error Code?

This fault can be triggered by a few different issues:

1. Internal failure of the control module – Over time, the electronic components in the module can degrade.

2. Electrical or wiring issues – Loose or corroded connections may cause a loss of communication.

3. Faulty sensors or connectors – A faulty sensor in the transmission can lead to incorrect readings and cause the module to malfunction.
