7 Series - E65 / E66 (2002 - 2008)
Discussion of BMW's 4th generation E65/E66 7 Series flagship. The E65 generated much controversy, due to its radical styling and iDrive user difficulties. Nonetheless, the E65 broke records to become the best-selling 7-series iteration ever, especially after its 2005 facelift.

Parking brake light is on?

I don't know what happened yesterday, I turned my car on and the iDrive is stating parking brake malfunction? I took it to my tech that usually does the up keep on my car. He sd that the parking brake motor is going bad? He sd it in the trunk around the spare tire..... So I asked him how much it will cost? He sd it's a dealer part and cost around 1000.... I was like ok I can not afford that at this time.....

Now my question is? I did some reading on the Internet and I saw a few post about a dieing battery? Well my tech mention that my battery is only about 60% good???? Can anyone here clerify this? Also my tech told me that the calippers were not engaging so it is ok to drive the car???? I'm not to confident driving my car with that yellow "P" on in my guage cluster.....
I did replace rear calippers with OE ones and parking sensors.

The other thing is when I turn the car on and push the parking brake button the light will dissapear and u can hear the motor working in the rear.... As soon as I put the car in gear the iDrive pops up and reads parking break malfunction...


Can anyone out here help me with this issue? Please email me or even call me haha.... I just want to see I there is another cost efficant way then spending 1000 plus for a little motor.

check and make sure the motor isn't working before you go out and replace it. remove the truck mat and you'll see a black cover above the spare, remove the cover and have someone activate the parking brake, mine works perfect yet i have the light meaning its probly something else like the battery

according to this picture, you have either actuator unit problem or could be something wrong with those cables.

make sure the motor is working first. Also would be cool to test your unit on somebody else car.

When i try to activate the parking brake i do hear the motor in the trunk so that tells me that the motor is working.Really interested about the part you mention if only you could be more specific as to what part it is or what location on the car i can find it.THANKS

Re:

It is probably the parking brake gear. Do a search for it and you will see it's a very common issue You can buy the gear for ~ $150 at odometergears.com and it even comes with a lifetime warranty. There is a youtube video that should be on that page that shows you how to replace the broken gears. Unfortunately you will need a bench vise and hydraulic press (or find someone with one!) The original ones are made out of Nylon so after awhile they get brittle, fracture, and crack..also the new ones are a better type of plastic I believe.

I have seen the battery cause this problem only once. Most of the time it is the gears inside the actuator. I would not bother with the gears unless you want hours of frustration and cursing lol. Another easier route is to buy a good used actuator , they are the same from 02-08 7 series. I have replaced 4 actuators already ranging from 03 745s to 2007 750s. No programming necessary if you take the used route. Take little black cover off(2 Allen bolts), than you will see 2 small screws holding small metal bracket (take those off), than take 3 10mm bolts off that secure actuator to body, use emergency release tool in trunk kit and turn until you see parking brake ends facing outwards, now that the actuator is loose you will see the metal clips near the bottom under the actuator, use a flat head to push each side in and release cable from actuator. Once you install the replacement actuator , repeat the steps in reverse , clear codes stored in parking brake module . Now turn ignition on , not engine, actuate parking brake 3 times( each time being a sequence of on and off within 5 second intervals. Done.. Easier route in my opinion and if you buy a new actuator you have to take to dealer to do some type of programming($330). That's why I recommend getting a used one($200-$300) at most BMW salvage yards. Good luck

Thank you for these instructions! I never could figure out how to unhook the Bowden cables even with them in the service position. I will look for this metal clip you speak of. I had been working on the parking brake sitting in the trunk where the spare wheel should be and ruining my back and neck in the process because TIS instructions say in order to remove the cables from the module you have to disconnect them at the wheels.

No prob, my back did not feel that good either the first time i did this job. It is not necessary to disconnect the cables from the wheels, I will post a picture tmrw of the location of the clips, have a spare actuator laying around.

Is that actuator working? I might need one. I had done the odometergears.com repair a month ago and now something got out of alignment on the shaft that I bench pressed together. The spring pin holes no longer line up. I'm thinking of just putting in a used one and calling it a day.

I have a similar issue. My garage sits on a not too high hill, but high enough for the car to roll. I pulled the car from the garage facing downwards. Put the car in Park, released the brake pedal and instantly press the emergency parking button. Immediately I heard a noise coming from behind the rear left wheel and the instrument parking light turned yellow. I'ts been like that for several weeks now. The car sits in the garage most of the time anyways, however that day I had to use it for a little while. By the time I got back to the house I had driven it for close to 100 miles without any brake trouble other than the yellow light on. After reading some of the posts in here...seems like I'll be looking to buy the actuator or the parts to fix it. I'm not sure I want to go thru all the hassle of doing it myself. I'll see once I pulled the actuator out one of these days.

You have to take it to the dealer or buy a cable and reset it yourself. Try pressing the parking brake 3 times with a few seconds in between.

What cable can I buy to reset it? Do you guys know how much and where can I buy the software to programmed the car? because pretty soon I'm going to need a new battery and I need to register the battery 2 so might as well just try to get the equipment if is not too expensive. Thanks for your help

That's so weird I'm trying exactly step by step what you post it... Ignition on, and pressing the Parking button 3 times with intervals of 5 seconds but the light is not coming off and I dont hear or see the unit moving, I'm 100% sure the motor was good before pulling the unit out. Could something burn it out? when I work on the car I always unplug the battery.... I guess I will have to take it to the shop to get it program.
