No. I have the OM606 engine. Hydraulic lifters eliminate the need for mechanical valve adjustments as on the older diesels.
About the only thing I've done abnormal on the car in 7 years is replace two glow plugs. (And when the second one went, I actually replaced the 5 that hadn't been changed yet, since they are cheap and I didn't want to take the manifold off again to change #3...)
