Default 1998 A8 4.2L MAP Sensor location?

I'm a new A8 4.2 owner.

I got a code: Manifold absolute pressure or Bar pressure low input.

Would someone please tell me where the MAP sensor is located?

Bentley shows no such code and no such part.

If it exists, it would be inside the trans or trans valve body.

There is no MAP sensor. The V8 engine uses an airflow meter and throttle position sensor.

I would suggest scanning it with VCDS from Ross Tech which will give you much more accurate codes than a generic OBDII scanner.
