Removal and installation coils
Remove engine covers "1" and "2" upwards. Disconnect the fuel. line "4" and line "1" from the absorber with activated carbon on the air duct body. filter and on the air duct tube. Disconnect vacuum hose "2" from the air duct hose connection. Remove the air duct hose by loosening the hose clamp "3" and opening the clamps "arrow". Remove the air duct housing. filter.
Unscrew the arrow bolts and disconnect the plug connectors from the coils. Gently press the wire harness downwards. "Pos. 1, 2" do not take into account.
Cylinder bank 2 (left): Loosen the bolt "arrow". Disconnect the connector of the low coolant level indicator sensor "F66" from below on the expansion joint. tank and put the expansion tank with coolant hoses "1" and "2" connected to the side.
Unscrew the arrow bolts and disconnect the plug connectors from the coils. Gently press the wire harness downwards. "Pos. 1, 2, 3" do not take into account.
All
Remove the coils using the "T40039" puller.
Installation in reverse order.
Removal and installation knock sensors "G61"/"G66"
Remove the compressor. Remove the lower parts of the left and right intake manifolds. Remove the plug connector "1" of the knock sensor 1 "G61" from the right bracket and disconnect it. "Pos. 2" and "arrow" should not be taken into account.
