Audi P006800 fault elimination method is as follows: 1. Remove the throttle hose. 2. Open the throttle flap. 3. Clean with a brush. 4. Spray with cleaning agent. 5. Reinstall the hose. More information about the P006800 fault: 1. P006800 refers to the absolute pressure of the manifold. 2. The function of P006800 is to measure the pressure in the intake manifold. The powertrain control module uses the difference between the intake manifold pressure and atmospheric pressure as the basis for determining the basic fuel injection quantity of the injector, helping the engine achieve the optimal air-fuel ratio under different loads.
My Audi A4 recently triggered this P0068 trouble code, and I always feel sluggish acceleration and slow throttle response when driving. Initially, I did a quick check myself and found that the throttle position sensor connector was a bit loose, so I reconnected it tightly and test-drove the car, but the light still came on. Later, I went to the 4S shop, where the technician used a diagnostic tool and found that the mass airflow sensor signal was unstable. They recommended cleaning the throttle body, but the issue persisted, so they replaced the sensor, which finally cleared the fault. Just a heads-up—if ignored, this problem can easily cause engine misfires or even sudden stalling, which is very dangerous on highways. It’s best to first check connections and connectors yourself, reset the code with an OBD tool, and monitor it for a few days. If the issue recurs, get it fixed professionally right away—don’t skimp on safety.
