Air Plenum Chamber

There is a current Service Action on some 2002 model year Audi A4 vehicles and Audi A6 vehicles.

Service Action 51 B 7 JU Recall |

Service the Air Plenum Chamber to improve drainage.

What is the problem?
In some 2002 model year Audi A4 and Audi A6 vehicles moist debris might clog the air plenum drain area and water could leak into the brake booster. In rare cases, during cold weather, frozen water may impede proper performance of the brake vacuum assist.

These conditions can be prevented by ensuring that the air plenum area is maintained regularly to keep it clear of dirt and debris. This helps to avoid the water drain holes from becoming blocked. Please refer to your owner's manual for additional information, including important warnings about working in and around the engine compartment and air plenum area.
