- 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.
- 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.
- 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.
