Service As the oil loss in the area of the cylinder head cover may involve two different issues, proceed as follows to clearly determine the source of the leak. 1. Remove the engine compartment cover and the heat shield below it. 2. Remove the upper noise insulation of the affected cylinder bank (Figure 1). Figure 1. Removing the upper noise insulation.

Remove the Audi valvelift system actuator of the affected cylinder. A. If there is a substantial quantity of oil below the Audi valvelift system actuator (illustration), the cause of the leak is the O ring of the Audi valvelift system actuator. Replace the Audi valvelift system actuator with O ring, clean the engine compartment and if necessary replace the noise insulation (if it is full of oil) (Figure 2). B. If there is no substantial quantity of oil below the Audi valvelift system actuator continue with Step 4! Figure 2. Oil in the Audi valvelift system. 4. Remove the lower noise insulation. 5. Locate the affected cylinder. Here oil should have gathered in the area of the injector (Figure 3) and the noise insulation should also be full of oil. Figure 3. Locating the affected cylinder.

Remove the cylinder head cover and the seal (Figure 4). Figure 4. Remove the cylinder head cover. 7. Inspect the seal groove in the cylinder head cover and remove any cast metal debris (Figure 5). The debris can be removed with a small flat screwdriver (Figure 6). Figure 5. Before the repair. Note: Make sure not to damage the seal groove! For vehicles with a production date starting 10/01/2018, please take a picture of the metal casting debris before filing, and upload to DOC-IT with the corresponding VIN of the vehicle. Figure 6. After the repair. 8. Install a new seal, re-assemble camshaft cover, clean the engine compartment, and if necessary replace the noise insulation (if it is full of oil).
