Another E70 Handbreak Problem

[psyka]

Hey Guys, i am new around here.
Also very new in the world of the X5.I find it a very nice an confortable car but electronically with a few problems.

So here is my problem;

I have bought the car with a Handbrake malfunction.Previous owner had his handbrake blocked and could not move the car anymore,he had no idea that bmw has a small hammer in the boot that is used to manually release the handbrake in case that something like this happens.

Took the module out, installed new cables and checked that everything is oke in the handbrake module, reinstalled it, but no luck.
I had a look with ISTA-D and i'm getting the error. Emergency handbrake release detected.And cannot work around this.

If i have the car in D and i let it gently roll in front and in the same time i pull the inside handbrake button the car stops...but as soon as i release the button it starts rolling again.

So if my understanding is good, the handbrake is working but will not stay on.

Did anybody had such an experience ? Would appreciate some feedback.

Thank you,


Johnny

I had mine lockup once, used the tool to release it, and haven't had an issue since. I wonder if it thinks it's still malfunctioning? Maybe there's a sensor issue with the car not thinking it's in Park? I know you can pull the lever while in drive and activate the break, but it won't hold once you release it if it's in Drive (learned that hooking up the boat last summer). Maybe it's not seeing it in park?

The parking brake has 2 modes. When the ignition is on, activating the parking brake uses DSC to apply the regular brakes (that's what you're experiencing). When the ignition is off, activating the parking brake activates the parking brake actuator which pulls on the Bowden cables to set the parking brakes.

If you have the ignition off and activate the parking brake, can you hear the actuator working?

Is the emergency release cable installed properly on the new actuator unit?

Did you perform the proper reset procedure after the emergency release ?

If not do this:

Car in park

Ignition on in position 2

Foot hard on foot brake throughout.

Press parking brake switch DOWN and hold for 30 seconds

Lift parking brake switch UP and hold for 30 seconds
