No, there is absolutely no possible way i can be any more specific. If you do not know where the EMF control module is located, maybe this is the question you should be asking? Because if you knew where it was located, you would be able to find the connector without asking your question.

Have the X5 at the dealer yesterday and they found nothing wrong with the wiring, so they updated the software and it seems fine now. Thx guys.

I just found out the rear view camera has full view display option on iDrive after the software updated, but lost the steering's easy entry/exit feature.

Parking brake malfunction light came on again, dealer said that the actuator is no good this time. Total cost of repair is $2169.00, luckily, I only have to pay $200 and extended warranty takes care of the rest.

So my brakes parts are on order and in the meantime I get the infamous "Parking Brake Malfunction". After reading all the posts I could on the issue, I am thinking I will do the following in the order written:

1. I usually engage the parking brake before turning engine off and now understand that this could cause errors. i will release the parking brake manually, drive it around for a bit and then engage the parking brake once the engine is off. Wait at least 30 minutes to see if yellow dash warning has disappeared. Apparently 30 minutes or so is required to allow all on-board computers to reboot/reset.

2. Examine the connector to the parking brake control module and actuator. If looks suspect try to repair this.

3. Install new brake rotors, pad and sensors all round. Was going to do this anyway and parts are already ordered.

4. Replace the control module.

Please let me have any recommendations or suggestions?

I have a few questions:

1. Where is the control module (EMF) located?

2. I have read that if the control unit is replaced that it needs to be "reprogrammed". Is this true? has anyone attempted this themselves? I have NCS expert for my E46 M3, can I use this if I need to reprogram the control module on the X5?

3. Anyone have part number for the control module that was replaced?


In the interests of sharing valuable information with the community I will post back my findings and do a DIY if I replace the control unit.

Good document on the EMF that I thought I would share

Couldn't wait till weekend so I manually released the parking brake, took the x for a drive and then left the vehicle locked fr an hour. On return I found that the error was still there plus the parking brake does not engage when button is raised.

I crawled underneath to locate the emf control module and actuator. All seemed dry and the connector looked fine with no signs of shorting. I will wait until the weekend and attempt to remove the module to take a closer look.

As the parking brake button is not doing anything at all including re-engageing the parking brake. This makes me question if the module is even getting power. If the pins on the connectors are fine when i remove them this weekend I am thinking it must be the control module/actuator or a fuse. Just searching for a fuse to the EMF.

I think once you have pulled the manually unlock lever, the parking will no longer working until the problem is fixed. Someone had posted a repair procedure of the parking brake actuator in the forum while ago, do the search and hope it helps you.
