Just changed the oil, oil filter, and both primary and secondary fuel filters (one's a spin-on and the other basically a screen housed in the spin-on's filter head.
I've done this before on this car (1997 E300D), my previous Mercedes, and my diesel Ford truck many times, so I know about air in the fuel lines and to fill the fuel filter before installation. I also know to expect a little rough running as the air is purged. This time something went wrong. The car ran for a while and died. We restarted it, and it ran for a while again. We shut it off, or tried to and it acted like it didn't want to shut down. Now it won't start at all. Got a check engine light. Hooked up a reader and the car has set code P0215, which is "Engine Shutoff Solenoid Malfunction". I erased the code. The filters are full. The car is full of fuel. We have even tried the owner's manual instructions regarding "running out of fuel" to no avail. What have we possibly caused by changing the fuel filters, or servicing the car? We've done this before with no problems. I will have the car towed to my favorite Tech's shop tomorrow. The way it's going with this car, I expect to receive both a Birthday card and a Christmas card from him this year. My last Mercedes was "bullit-proof". Not this one. Any suggestions? I feel frustrated and pretty much foolish. Thanks in advance for anyone's help. Steven

In the course of all the filter changing, could you by chance have knocked the line off the shut off solenoid? I know it happens often on the vacuum shut-offs, the vacuum line gets bumped or knocked off during a filter change, then no stopee. Knocking a lead off the solenoid would probably give you your fault code, may even affect engine performance and would definitely cause a fail to shut down.
Mind you it's just a guess.

Make sure that all of the o-rings are new and in place. I have seen this before when the prefilter o-ring leaked air in the system. I have seen the shut off actuator fail. It is electric on your car and has a fuel temp sensor incorporated.

Mike and Donnie, thanks for the replies.
Mike, I've been there before on the "no stopee" vacuum routine on our old car (300SD). Sometimes I wish we still had it. Donnie, all o'rings are in place. The car did run after the fuel filter change for 5 minutes or more. In fact, we moved it to another place on the driveway before the trouble started. When we shut it down after starting and running it twice, it acted like it didn't want to stop, and then set the code. I erased the code, but if the shutdown actuator failed, it will still be faulty. It isn't just some random code, I guess. I feel better .... I think. Did I do something wrong during the filter change to cause the actuator to fail? Or am I just another victim of circumstance? Also, I looked "high and low", and I cannot find a priming pump on this car. The old SD had one. Did they leave them off of the newer cars? Again, thank you both for helping me. I appreciate it very much.
