Complementary Modification:

Replace hood release latches

The hood release handle located in the interior of your BMW Z4 is used to open the engine hood. The handle is connected to the hood latches via steel cables. The steel cables are joined in the center and separate for easy servicing. Although both cables are housed in plastic sheathing, they are still prone to corrosion.

The hood release cables consist of two separate parts. One cable runs from the hood release handle to the cable junction under the hood. The other cables (serviced as one part) run to each hood latch. The cables that run to the hood latches tend to crack, allowing moisture to enter the cable. Once this happens, the cables lifetime is greatly shortened. If your cables are sticking, your hood release handle won't return when you open your hood. It may be time to replace the cables. First check if the latches need to be cleaned and lubed. If the latches are in good shape, replace the cables.

Remember your car may have been serviced before and parts replaced with different size fasteners used in the replacement. The sizes of the nuts and bolts we give may be different from what you have so be prepared with different size sockets and wrenches.

Protect your eyes, hands and body from fluids, dust and debris while working on your vehicle. If working with the electrical system, disconnect the battery before beginning. Always catch fluids in appropriate containers and properly dispose of any fluid waste. Recycle parts, packaging and fluids when possible. Never work on your vehicle if you feel the task is beyond your ability.

The hood release cables consist of two separate parts.
Figure 1

The hood release cables consist of two separate parts. One cable runs from the hood release handle to the cable junction (red arrow) under the hood. The other cables (serviced as one part) run to each hood latch. The cables that run to the hood latches (purple arrow) tend to crack, allowing moisture to enter the cable.

Working at the left side of the front fender near the radiator support, open the hood release cable junction box.

To remove the right side latch, remove the 10mm washer reservoir fastener (red arrow), then lift and move the reservoir to the side. Then unhook the cable as you did on the left side (purple arrow). Pull the cables out of the mounting hooks, they will open to allow the cables to be removed. Then reverse steps to install the new cables.

To replace the latch, remove the two T30 Torx hood latch fasteners (red arrows).

Slide the cable into the passenger compartment.

Slide the cable into the passenger compartment. The cable can be seen from above (red arrow). But it is difficult to access.

I prefer to work with the left front wheel well liner removed.
Figure 15

I prefer to work with the left front wheel well liner removed. Working in the wheel well, you have clear access to the cable (red arrow). Slide the cable into the passenger compartment. Then pull it through the firewall. Install the new cable to the hood release lever. Then reassemble the hood release handle and footwell trim panel. Connect the new cables together. Be sure that the cable end is securely in the catch. Then close and reattach the cable junction to the body. Check the operation of your hood release cables by closing the latches with a flathead screwdriver and releasing them with the handle. If all is well, reassemble vehicle.
