Then remove the two ignition coils closest to the Valvetronic motor.Large Image Extra Large Image.Figure 8. Remove ignition coil from cylinder head by pulling straight up.If coil resists, twist when pulling up to break free from spark plug.The ignition coil rubber boot can become stuck to spark plug over time.Large Image Extra Large Image.Figure 9. You can also use a flathead screwdriver to lever coil up and out of cylinder head.Be very careful using this method as coil is made of plastic and easily damages.Large Image Extra Large Image.Figure 1. 0Disconnect Valvetronic motor electrical connector by squeezing tabs green arrows and pulling connector off motor.Large Image Extra Large Image.Figure 1. 1Using a 4mm Allen, rotate Valvetronic motor clockwise manually using hex located at rear of motor.Rotate motor slowly until you feel a slight resistance, then stop.Large Image Extra Large Image.Figure 1. 2Next you will have to remove the fastener located at the bottom of the Valvetronic motor.This fastener attached motor to a small bracket mounted to the valve cover.Large Image Extra Large Image.Figure 1. 3Remove lower E8 Valvetronic motor fastener.Large Image Extra Large Image.Figure 1. 4Remove two upper Valvetronic motor E8 fasteners.Large Image Extra Large Image.Figure 1. 5Using a 4mm Allen, rotate Valvetronic motor counterclockwise manually using hex located at rear of motor.Rotate motor slowly and guide out of cylinder head.Store Valvetronic motor in a safe place.Large Image Extra Large Image.Figure 1. 6Now its time to take care of the oil leak caused by a faulty Valvetronic motor gasket.This photo shows a puddle of oil from the leaky gasket.The oil gathers under the motor in the top of valve cover.Large Image Extra Large Image.Figure 1. 7Remove two T3.Torx fasteners for the Valvetronic motor gasket.Large Image Extra Large Image.Figure 1. 8Using a flathead screwdriver, gently lever gasket out of valve cover.You will not need a lot of force to do this, gasket will pop right out.Once gasket is free from valve cover, remove and discard.Large Image Extra Large Image.Figure 1. 9When installing new gasket, be sure black stripe is facing up.Large Image Extra Large Image.Figure 2. 0Then press into valve cover until fully seated.Install Valvetronic motor in reverse order of removing.Use a 4mm Allen bit to rotate motor clockwise while installing into cylinder head.Once flush with cylinder head, install fasteners and tighten.Remember, if you removed aluminum fasteners, replace them each time they are removed.Be sure wiring harness is routed as it was before and engine covers are properly aligned.Turn key to ON position for 3.OFF, then ON again for 3.Large Image Extra Large Image.Figure 2. 1When repairs are performed on the Valvetronic assembly the limit stops have to be relearned.You will need access to a BMW scan tool to do this procedure.The limit stops are the mechanical limit stop, end to end of rotation of the eccentric shaft.The DME digital motor electronics records these stops via the eccentric shaft sensor to determine mechanical adjustment limits of the eccentric shaft.With that said, when removing the motor to replace the gasket you are not changing the mechanical position of any Valvetrnoic assembly components, a relearn is not always needed.
