It could be that you got some water on your serpentine belt and that will cause it to squeak. Try buying a can of "belt dressing" from an auto store and spray it all over your belt and see if that will stop it. It's a cheap and easy thing to try before replacing expensive parts. Hope this works for you, let me know how it goes. Goodluck!

Check the glow plug rail, Its easy to do, get a thick electric cable and hold it on the positive side of the battery and then onto the Rail connecting the glow plugs, do this for 20-30 seconds and try to start the engine, or better still get a friend to start the engine while you hold the cable on.
Diesel engines work on heat and compression, so if your glow plugs are weak then you wont get the heat needed to create combustion.
Testimonial: "I'm not certain whether this is the source of the problem, but its certainly worth checking out. Thanks for taking the trouble to respond "

DTC P0243 - Turbo/Super Charger Wastegate Solenoid A
Description: Open or shorted condition detected in the turbocharger wastegate solenoid control circuit.
Here is the flow chart for that code (some images could need to clicking for zoom)...
P0243-WASTEGATE PRESSURE CONTROL PWM
For a complete wiring diagram Refer to Section 8W.
When Monitored: When the ignition is on.
Set Condition: The ECM detects an open or short circuit in the Wastegate solenoid circuit.
Possible Causes
DAMAGED WIRING HARNESS OR CONNECTORS
WASTEGATE SOLENOID
(F504) FUSED IGNITION SWITCH OUTPUT OPEN
(K139) WASTEGATE SOLENOID DRIVER CIRCUIT OPEN
(K139) WASTEGATE SOLENOID CIRCUIT SHORTED TO GROUND
(K139) WASTEGATE SOLENOID DRIVER SHORTED TO VOLTAGE
(K139) WASTEGATE SOLENOID DRIVER CIRCUIT SHORTED TO ANOTHER CIRCUIT
ECM
INTERMITTENT CONDITION
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING)
Diagnostic Test
1. DAMAGED WIRING HARNESS OR CONNECTORS 
Turn Ignition off.
Disconnect the ECM harness connectors.
Disconnect the Wastegate Solenoid harness connector.
NOTE: Check connectors - Clean/repair as necessary.
Are any wires or pins damaged?
Yes
Repair or replace any damaged wire or connectors.
Perform POWERTRAIN VERIFICATION TEST VER - 1 (DIESEL).
No
Go To 2
2. WASTEGATE SOLENOID 
Reconnect the ECM harness connector.
Reconnect the disconnected Wastegate Solenoid harness connector.
Turn the Ignition on, engine not running.
Disconnect the Wastegate Solenoid harness connector.
Connect an incandescent test light across the supply and driver pins at the Wastegate Solenoid harness connector.
NOTE: The ECM will perform a self check of the circuit after approximately 30 seconds, which should light the incandescent test light.
Does the light illuminate brightly after 30 seconds of being connected?
Yes
Replace the Wastegate Solenoid.
Perform POWERTRAIN VERIFICATION TEST VER - 1 (DIESEL).
No
Go To 3
3. (F504) FUSED IGNITION SWITCH OUTPUT OPEN 
Connect an test light between the Wastegate Solenoid connector Fused ignition switch output circuit and battery negative.
Compare the test light brightness to that of a direct connection to the battery.
Does the light illuminate brightly?
Yes
Go To 4
No
Repair the open (F504) Fused Ignition switch output circuit.
Perform POWERTRAIN VERIFICATION TEST VER - 1 (DIESEL).
4. (K139) WASTEGATE SOLENOID DRIVER CIRCUIT OPEN 
Disconnect the ECM harness connectors.
Measure the resistance of the Wastegate Solenoid driver circuit between the Wastegate Solenoid harness connector and the ECM harness connector.
Is the resistance less than 10 Ohms?
Yes
Go To 5
No
Repair the open (K139) Wastegate Solenoid control circuit.
Perform POWERTRAIN VERIFICATION TEST VER - 1 (DIESEL).
5. (K139) WASTEGATE SOLENOID CIRCUIT SHORTED TO GROUND 
Measure the resistance of the (K139) Wastegate Solenoid driver circuit between the Wastegate Solenoid harness connector and battery negative.
Is the resistance less than 10 Ohms?
Yes
Repair the (K139) Wastegate solenoid circuit shorted to ground.
Perform POWERTRAIN VERIFICATION TEST VER - 1 (DIESEL).
No
Go To 6
6. (K139) WASTEGATE SOLENOID DRIVER SHORTED TO VOLTAGE 
Measure the voltage between the (K139) Wastegate Solenoid driver circuit at the Wastegate Solenoid connector and battery negative.
Is the voltage less than 1 volt?
Yes
Go To 7
No
Repair the (K139) Wastegate solenoid driver shorted to voltage.
Perform POWERTRAIN VERIFICATION TEST VER - 1 (DIESEL).
7. (K139) WASTEGATE SOLENOID DRIVER CIRCUIT SHORTED TO ANOTHER CIRCUIT 
Measure the resistance between the (K139) Wastegate Solenoid driver circuit in the ECM harness connector and all other circuits in the ECM harness connectors.
Is the resistance less than 10 Ohms?
Yes
Repair the (K139) Wastegate solenoid circuit shorted to another circuit.
Perform POWERTRAIN VERIFICATION TEST VER - 1 (DIESEL). (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING)
No
Go To8
8. WASTEGATE SOLENOID 
Reconnect the ECM harness connector.
Reconnect the disconnected Wastegate Solenoid harness connector.
Turn the Ignition on, engine not running.
Disconnect the Wastegate Solenoid harness connector.
Connect an incandescent test light across the supply and driver pins at the Wastegate Solenoid harness connector.
NOTE: The ECM will perform a self check of the circuit after approximately 30 seconds, which should light the incandescent test light.
Does the light illuminate brightly after 30 seconds of being connected?
Yes
Refer to the INTERMITTENT CONDITION Symptom (Diagnostic Procedure).
No
Replace the ECM.
Perform POWERTRAIN VERIFICATION TEST VER - 1 (DIESEL).
