⌛ Prepare E88 hall sensors for E89 use

[RobbiZ4]

E89 hall sensors (HS) on the hydraulic rams are very expensive as spare parts. Alternatively, E88 hall sensors can be fitted. These HS use the same housing format, but are supplied without connectors.

What is required:

• Hall sensor: https://www.realoem.com/bmw/en/showpart ... 4347190735

• 2 MQS female pins per HS

• A MQS crimp tool

Preparing these E88 hallsensors is easy going:

• Remove the zip tie from the hydraulic ram, that fixes the rear hall sensors plug. Take a photo before removing it!

• Both hall sensors are clipped into the right hydraulic ram in the trunk. You can unmount it by pushing a tiny screwdriver between the ram and the HS housing

• Shorten the 2 wires of each new hall sensor according to the lenghts of the old hall sensors, they are different

• Crimp a new pin on each wire

• Twist both wires to get the wiring a bit more compact

• Plug both wires into a new housing.

• Important: pin orientation is according to he old hall sensors - brown to brown, colour to colour!!. One old HS has a yellow wire, the new one is red. Don't mind, just colour to colour

• Don't forget to place a new zip tie sorrowly(!) around the hydraulic ram to fix the plug and the 2x2 wires as initially removed
