Technical Service Bulletin 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. 3. 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.
