13 51 070 Removing And Installing/Replacing Right High-Pressure Fuel Pump (N63)

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2014 BMW X6, 2013 BMW X6, 2012 BMW X6, 2011 BMW X6, and 2010 BMW X6. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:

Observe warning on cylinder head cover.

Disconnect battery negative terminal  (risk of fire due to short-circuiting on removal). See 61 20 900 DISCONNECTING AND CONNECTING BATTERY NEGATIVE LEAD .

Electric fuel pump starts up automatically when door is opened!

Carry out installation work on fuel system only with coolant temperature below 40°C.

IMPORTANT:

Wear full face guard and protective gloves.

Fuel can emerge spontaneously at high velocity when the high-pressure line is released!

IMPORTANT:

Adhere to conditions of absolute cleanliness when working on the high-pressure fuel system.

Introduced contaminants can cause malfunctions in the system!

  • Do not allow any dirt particles or foreign bodies to get into the system.
  • Remove all traces of dirt before removing pipes or individual components.
  • Use only fluff-free cloths.
  • Seal all fuel system openings with protective caps or plugs.
IMPORTANT:

Ignition coils must not be fouled by fuel.

The resistance of the silicone material is reduced significantly by contact with fuel, which may cause the ignition coil to fail!

Cover ignition coil with suitable means.

Necessary preliminary tasks: 

Recycling: 

Fuel escapes when fuel lines are detached.

Catch and dispose of escaping fuel.

Observe country-specific waste-disposal regulations.

Release clamp (1). Disconnect charge air line (2) to exhaust turbocharger.

Picture shows the left side, the procedure for the right side is identical. Pull off hose (1) from clean air pipe (3). Release screw (2).

Tightening torque 13 71 1AZ. See 13 71 AIR INTAKE DUCT . Pull off clean air pipe in direction of travel from exhaust turbocharger. Check seal on clean air pipe and renew if necessary.

Unlock plug catch (1) on ignition coil (2) and unplug connector. Slowly pull out the ignition coil (2) in an upwards direction with no jerky actions.

NOTE: There is a possibility that the silicone tube will tear and therefore be destroyed. This procedure is applicable to all ignition coils.

Installation note:  Position the ignition coil (1) and gently push it to the limit position, if necessary by twisting it back and forth slightly. Then check anti-twist lock. The rubber cap must completely surround the sealing collar of the cylinder head cover.

NOTE: If rubber parts are squashed, the ignition coil can slip out again during engine operation.

Installation note:  Push connector (1) with connector catch (2) open onto ignition coil. Carefully close connector catch (2) in direction of arrow. The connector catch must snap into place without great effort. The connector must be positioned on the counter piece with hardly any gaps when the locking lever is being closed. In the process, the cheeks of the lever are positioned inside the counter piece.

NOTE: The locking lever can become deformed if it is not installed correctly. This means that there is no longer a safety lock on the plug connection. As a result, the connector can slip out during engine operation (loose contact, misfiring).

Important!  High-pressure pump can be pretensioned by camshaft cams! Slightly slacken screws (1) of high pressure pump (2). If the high pressure pump is forced out, the engine will have to be turned to bring the camshafts to a different position. Otherwise it will not be possible to install the high-pressure pump! Release screws (1). Replace screws. Screws are coated with a screw locking agent.

The pump plunger can fall out when the high-pressure pump (2) is pulled out! Detach high-pressure pump (2) and remove. Engine oil can emerge when pulling off the pump; have cloths ready. Installation note: Before installing the high pressure pump, the cam of the high pressure pump drive must be turned to BDC. To do this, twist the engine if necessary in the direction of engine rotation to the central bolt of the crankshaft. Adhere to tightening/torque sequence.

Install high pressure pump (2). Replace screws (1). Screws (1) are coated with sealing compound.

Installation note:  Provisionally fasten screws (1) on high pressure pump (2) and tighten alternately in 90° increments until final tightening, otherwise the piston may break as a result of tilting!

Tightening torque 13 51 1AZ .
