But the real issue isn't the job, it's the price these things cost. $1K for the eccentric shaft and $500 for the actuator. Then you might have to replace the oil sprayers and bearings the shaft sits on which is also stupid expensive. Also if BMW decided to use their awesome torque to yield bolts you can expect another huge bill in bolts.
