Parking break error
 

My e70 of 2007 received the famous parking break error, the orange light in the dash board has lit on.
Brought the car to a Indy nr 1 that changed the small motor inside the EMF module. Took the car back and it still had the same problem. So I changed to another Indy, this Indy was a bit smarter then the previous Indy he changed the fuse that was probably burned, but now the car still has the orange parking break light on the dash board. But when I slowly drive the car and activate the parking break the car stops so it seems the parking break module is working because before it didn’t do nothing if you pressed the hand brake button. But the problem I have now is when the car is stopped and you want to activate the hand brake it doesn’t work, is it because the car still has the error code in the computer ?
Does someone know what I have to do? Or is it still the EMF module that is malfunctioning ?

Anyone any tips ?
Does anyone know maybe if the emf module holds any error codes even after repair of the issues ?

I have the same problem. I tried replacing the switch, no help. I need to order the whole parking brake actuator assy. I would like to know if anyone has had luck with the rebuilt units off of ebay.

The rebuild units are around 400$ each and if you need to let a Indy do it they will charge you another 200-250$. I checked the price with the bmw dealer and it it will costs around 1400$ in totall for a new unit including installing it. So not taking the risk and wasting time on it

Before replacing the control unit and actuator, try reading and resetting the codes. Sometimes this will fix the issue. You'll need diagnostic software like ISTA.

I just ordered the cable on amazon. Does anyone have a step by step plan how to do the error erasing

Check out: BMW Coding Forum

When mine broke I bought a repair service on eBay for about $275. Included new cables installed and repaired the actuator error. Reinstalled myself and errors went away. Pretty easy fix.

The repair service is changing fuse , motor or cable.

I reset the codes and that fixed it. I am lucky I know, but just an FYI.

I just received the cable I ordered on amazon today. Will try to do it tomorrow. Any help with a step by step plan how to do the reset? I would really be thankful if you good

No fuses. That wasn’t what the service I bought was.

What I read is that most common fault are fuse , motor or cable. And if it’s the circuitboards chips related I think when you send it out for repair you will get the same unit with the same problem back

That sounds like a generic ‘fixya’ answer. Most common failures are gears in the module, cables, and/or solder issues (not in any order). The repair services can address any/all of that. They’ll bench test units for errors prior to returning. Of course this is all subject to buyer confirming what they’re getting when they buy a repair service.

Could there also be a possibility that after a repair of the motor inside or fuse that you need to reset the fault inside the emf module ?

I’m fairly confident there are no fuses in the module. Either way, I didn’t have to reset anything. Fix the problem and the light went away. But I also have the ability to clear codes and my experience may not be the same for everyone.

You're going to have to do a little more research but I thought there was a reset procedure during which the vehicle learns the parking brake position. Or maybe that was the sunroof. Or something else. I can't be sure of what I read or if it pertained to the E70. It might depend on the type of parking brake also. My X5d has a drum-in-hat style but some actuate the caliper and have to be reset when the pads are changed.

There is a fuse and it color is blue

Ok just received the cable and programs installed.
I see on my desktop BMW CODING TOOL , INPA , NCS DUMMY , NCS EXPERT , TOOL32 , WINKFP. I don’t see ISTA could be I have to buy the program then. Anyone know if I can use one of the programs I have now to reset the parking break module ?

I’m reading the codes and it’s still giving 600D ECU_EEPROM_DATA error and try to reset the faults but still the same. Anyone any suggestion ?

Sounds like a bad module. EEPROM is where the software for a module resides. That response leads me to believe that communication is not possible because of a hardware issue - internal component and/or interconnecting wiring issues - or the software is corrupted.

I brought the car to the dealer, they charge me 130$ only to tell me that I need to change the module price 1500$

Of course they did! Dealers don’t fix anything, they just throw parts at it. Do as I suggested and take it off and send it to a repair service for $300.
