  1. Remove 3 ignition coils. Pull off the cable plug on the ignition coils. Unscrew the two M6 x 25 pan-head screws (hexagon socket a/f 5), pull the ignition coils out of the spark-plug recess.
    NOTE:
    • If the camshaft adjustment valve is to be removed, the O-ring and the oil strainer must be replaced.
    • The cover with integral seal for the camshaft adjustment valve must be replaced.
  2. Pull off the cable plug on the camshaft adjustment valve. Remove the holder and the cover for the valve on the cylinder head cover. Unscrew the two M6 x 20 pan-head screws (hexagon socket a/f 5), remove the connection cable for the camshaft adjustment valve from the sheetmetal bracket and remove the holders. Pull off the valve cover.
  3. Remove cylinder head cover. Repeat step 4 as with cylinder bank 1-3.
    NOTE:
    • Once you have levered off the cylinder head cover, check the O-ring on the oil extraction pump for damage (particularly in the disconnection point area). If the O-ring needs to be replaced, also unscrew the 2 lower M6 x 20 hexagon-head bolts and remove the pump.
  4. Remove the brown closure cap (45 mm) and 2 green closure caps.
