Is there any way to clean the EGR valve without taking it off? I believe mine is sticking open from time to time...

I am trying to actually follow emissions rules here guys. So, I understand about the ORM, Tunes, etc...no need to educate me on those.

There are some snake oils sold by Bardahl and Wynns which claim to clean EGRs. I don't see how they could be effective. It might be possible to do some in place cleaning through the inlet and outlet ports of the EGR, but the hassle of getting access would be about 95% of the work to remove the valve.
Removing the EGR valve is difficult.

got the official steps on cleaning the egr...

Notes:

I was also told to clean the 90 degree angle pipe immediately behind the FCV.

Removal:
1. Disconnect the negative battery cable.
2. Drain cooling system
3. Disconnect the electrical connector at EGR valve.
4. Disconnect coolant hoses at EGR valve and cooler and bolt.
5. Disconnect tube at the EGR valve housing.
6. Remove EGR valve housing to engine block fasteners.
7. Remove EGR valve and cooler assembly from vehicle.
8. Remove EGR valve retaining bolts and separate EGR valve from housing.
9. Remove Cooler to Housing retaining Bolts and separate cooler to housing.
10. Remove electronic actuator from the mechanical valve screws. 
11. Spray Mopar - Combustion Chamber Cleaner into the Carbonized areas of the mechanical valve chamber (depress valve and spray in chamber) and the housing chamber.
12. Clean with paint brush and let sit for 5 to 10 minutes, then rinse with Mopar - Brake Parts Cleaner.

installation:

Installation:
1. Clean all gasket mating surfaces.
2. Assemble EGR valve and cooler to housing. Torque bolts to 10.8N-m (95 in. lbs.)
3. Install EGR valve/cooler assembly. Tighten fasteners to 24.5 N-m (216in. lbs)
4. Install EGR pipe, Torque bolts to 32N-m (24ft. lbs).
5. Tighten ERG pipe clamps to 7 N-m (62in. lbs).
6. Tighten electronic actuator star head screws. 
6. Connect the ERG cooler hoses.
7. Refill cooling system.
8. Connect negative battery cable.

Sounds easy, but it isn't- due to the tight working clearances. Something that should be simple, like draining the radiator, is not that straightforward on the CRD. Removal of the battery shelf is also required. Drop a few bolts and sockets into the pit of oblivion and you may wonder why you even started on the job.

if you move the battery tray, are you able to see the egr valve?

The fuel filter head, battery tray, and hose from the CAC need to be removed to get at the EGR valve.
The FCV and elbow should also be removed. The exhaust tube to the EGR valve also needs to be disconnected. The cooling lines to the EGR cooler need to come off. They may need to be cut off and replaced with new hose. The electrical connector for the EGR solenoid takes some fiddling to get off. There are some other hoses and lines which need to be tied off or loosened to get access.

Just remember....the less fuel your Liberty uses, the less your Liberty pollutes.
