Someone else asked that question around twelve years ago but as not many of us had the diesel model the information is probably a bit thin on the ground.
This link may or may not help, as the answer wasn’t complete.

I don’t know if any of te below is correct as I copied it off the internet. 

1. Brake Booster CircuitRouting: A single, chunky, high-diameter hose runs directly from the vacuum pump to the brake servo unit.
Details: This line features a one-way non-return valve midway along the hose (near the oil dipstick) to ensure brake pressure is maintained.

2. EGR and Turbocharger CircuitRouting: The second, smaller vacuum line runs to the front of the engine, mounting near the left side of the cam belt cover by the EGR solenoid.EGR Routing: A short hose splits off and connects directly to the EGR solenoid, which then links to the EGR valve.

Turbocharger Routing: The line continues from the solenoid down behind the engine block to the turbocharger vacuum solenoid. From there, a hose runs above the clutch bell housing (between the engine and gearbox) directly to the turbocharger actuator.Troubleshooting Tip: If you notice a loss of turbo power or a hard brake pedal, trace these lines for splits, cracks, or loose connections. The small-diameter rubber hoses are prone to perishing over time.
