My first inlet port shutoff motor replacement job on OM642

Got an 09 E320 Bluetec in today that needs a new inlet port shut off motor. Any pointers or suggestions on the job that anyone can offer will be much appreciated. Looks pretty straight forward from what I've read so far.

Be gentle with plastic intake arm that attaches to port shutoff motor, gently pry plastic clip out and new one in , if you break the arm your going to need a new intake manifold , left or right.use plenty of lube on turbo bolts as necc, only use hand tools,clean working area real good, and dont drop any thing

Any secret to priming these things. To open the area up some I removed the cross pipe between the fuel rails. Now car won't start because it looks like it needs priming.

Well, when changing the fuel filter you just leave the key in position 2 for 30 seconds before starting the car. Then turn the key and it fires up like nothing was touched.

So, how was the job? I don't plan on finding out, personally....

Not much to it. Just take your time and as already stated don't drop anything. I would recommend having replacement plastic pieces that connect the actuator arm to the intake manifold arm. There are four of them and they break easily when you take em apart. Go slow dealing with the intake manifold linkage arm. It is my understanding you have to replace the complete intake manifold if it is damaged.

I was not impressed with the design having an electric motor actuated device in this area.

I found the cross over pipe between the two common rails loose at the passenger side. Snugged it down and car started after third "cycle".
