X-Type V6 3L AWD starting problems

Hello,

I bought my X Type two weeks ago. I drove it about 800 kilometers to bring it home and apart from a few vibrations at 110 km/h and above, it went pretty well.

But during a stop, I put back some gas (sp95), then I start again to go and check the tire pressure. I restarted again to free up space and went for a coffee. When I came back to start again, it wouldn't start. I turn the starter motor for a few seconds and nothing happens. I wait a bit and then it finally decides to start.

The end of the trip goes well. The next day, it starts fine. I stop and again it's hard to start. And these difficulties become more and more frequent. I've also got a DSC error message.

Here are the error codes I have on the dashboard:
DTC :
9205 -> B1205
A879 -> B2879
A141 -> B2141
9318 -> B1318
E510 -> U2510
D900 -> U1900

I also used a bluetooth ELM with Torque and here are the results:

------------------
P0171: System too Lean (Bank 1)
P0174: System too Lean (Bank 2)

Current faults
------------------
P0335: Crankshaft Position Sensor A Circuit
P1111: [BMW] Engine Coolant Temperature Radiator Outlet Sensor Low Input
[Chrysler] Intake Air Temperature (IAT) Sensor Circuit Intermittent High Voltage
[Ford] Intake Air Temperature (IAT) sensor intermittent high voltage
[Dodge] Intake Air Temperature (IAT) Sensor Circuit Intermittent High Voltage
[Jeep] Intake Air Temperature (IAT) Sensor Circuit Intermittent High Voltage
[Seat/Audi/Volkswagen] O2 Control (Bank 1) System too lean
[Triumph] Manifold absolute pressure sensor reverse connection
[Volvo] Intake Air Temperature (IAT) intermittent high voltage


So I changed the Crankshaft position sensor. I tested both the old and the new before installing the new and I got 341 ohms for the new and 355 for the old. And the problem still exists.

Any ideas?
