13 51 017 Removing and installing/replacing the high-pressure fuel pump

WARNING: This page is about a different car, the 2018 MINI Cooper, 2017 MINI Cooper, 2016 MINI Cooper, 2015 MINI Cooper, and 2014 MINI Cooper. However, it is still accessible from the selected car via links, so may be relevant.

WARNING: Observe warning on cylinder head cover.
Disconnect NEGATIVE BATTERY TERMINAL (risk of fire due to short-circuiting on dismantling).
Electric fuel pump starts up automatically when door is opened!
Carry out installation work on fuel system only with coolant temperature below 40 °C.

Attention !

Wear full face guard and protective gloves.

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

Recycling:

Fuel escapes when fuel lines are detached.

Catch and dispose of escaping fuel.

Observe country-specific waste disposal regulations.

Attention !

Adhere to conditions of absolute cleanliness when carrying out repairs 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 contamination before removing lines or separate components.
Use only lint-free cloths.
Seal all fuel system openings with protective caps or plugs.

Attention!

Ignition coils must not be contaminated by fuel.

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

Necessary preliminary tasks:

Remove PRESSURE LINE between rail and high pressure pump.
Remove FRONT RIGHT WHEEL ARCH COVER .

Removal:

NOTE: To disconnect the connector at the high pressure pump, the lock (1) needs to be pulled out in direction of arrow first. Then compress the lock (1) in direction of the connector housing, pulling off the connector at the same time.

Preparation for installation:

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.

Lay depth gauge (1) flat on high pressure pump flange.

Twist engine at central bolt in direction of engine rotation until the depth gauge shows that the camshaft has reached the BDC position .
