If your starter is beginning to make clicking sounds and not starting the motor, or it is not turning the motor over as easily as before it may be time to replace it before it leaves you stranded at the side of the road. Make sure to check the battery before replacing your starter.

The starter on the Porsche Cayenne is located in the V between the cylinder banks and involves a fair amount of work to get access to it. Once you have access replacement is not that difficult.

You need to disconnect the battery. It is a really good idea to disconnect both the ground or negative and the positive strap. There is a strap from the positive side of the battery to the starter. If you accidentally ground the starter with a tool while working on it you can cause serious damage to yourself and the car.

You are going to remove the intake manifold to give you room to access the starter.

You are going to remove the intake manifold to give you room to access the starter. Please see our article on intake manifold removal for additional assistance.

You will also need to remove the fuel rail.
Figure 2

You will also need to remove the fuel rail. Please see our article on fuel rail removal for further information.

With the fuel rail removed you will see the starter motor at the rear of the engine.
Figure 3

With the fuel rail removed you will see the starter motor at the rear of the engine. Begin by disconnecting the 13mm nut that holds the power cable (red arrow) and remove the line to the alternator; you will not be able to remove the cable on the starter solenoid until later. Use a 10mm wrench and remove the other electrical cable (yellow arrow).

The two bolts that hold the starter in place are E14 (red arrow).
Figure 4

The two bolts that hold the starter in place are E14 (red arrow). Make sure you use the right type and size of socket; you do NOT want to strip these bolts.

The bolt on the left side of the engine is easy to get access to (yellow arrow).
Figure 5

The bolt on the left side of the engine is easy to get access to (yellow arrow). For the bolt on the right side you will need to disconnect the connection for the right rear knock sensor. Use a set of extensions to remove the starter bolt (red arrow).

The bolt is difficult to remove due to its length and limited access, but at least like most modern bolts it has the washer built into it.

The bolt is difficult to remove due to its length and limited access, but at least like most modern bolts it has the washer built into it. Installation is tricky so be prepared to be patient.

There is a rubber cap over the rear of the bell housing.

There is a rubber cap over the rear of the bell housing. Pull this up and out.

With the cap removed you can lift the rear of the starter up and out.
Figure 8

With the cap removed you can lift the rear of the starter up and out. There is no need to remove any coolant or vacuum lines.

When installing make sure to replace the rubber cap correctly; it is marked M (red arrow) for facing the motor and G for facing the gearbox (yellow arrow).

Before installing the new starter make sure to clean and inspect the mounting area.
Figure 10

Before installing the new starter make sure to clean and inspect the mounting area. A surprising amount of dirt, debris and fluids can end up in this area. Installation is the reverse of removal.
