Wave Acceleration on 2.5L V6 6Zyl Engine

My A6 is accelerating in a wavy pattern.
The thrust steadily increases up to 3000 RPM, then the power briefly drops. The same thing happens again at 3500 RPM.
Does anyone have any advice?

John.

Hi!

Mildly wavy acceleration accompanied by a loss of power often indicates a faulty mass airflow sensor (MAF). This part can be replaced in just a few minutes. Therefore, a test drive with a different MAF sensor is recommended for diagnosis.

Hello,

If you have the opportunity, start by reading the measurement data blocks. An overview can be found in the error database.
