1. 2013 F10 535i Auto Hold & Parking Brake Malfunction
   

   Hello, I have searched relentlessly for the cause of the following.

   Vehicle:
   2013 BMW 535i M-Sport 93K

   Issue:
   While driving the vehicle intermittently I will get the Parking Brake Malfunction message on the iDrive screen. You can click OK and it will go off and stay off but then at times it comes right back on sometimes at 5-10 second intervals for 5-10 minutes. I am also getting the Auto Hold malfunction message randomly as well.

   The parking brake seems to mechanically work fine. When it is applied you can hear the mechanical gears engage and it does hold the car in place.

   Attempted Fixes:

   I replaced the control module in the trunk located by the battery with a used model that was newer than mine. Result: Did not fix
   I have disconnected the battery for 30 minutes in an attempt to reset any ECU’s. Result: Did not fix
   Pulled fuses for the parking brake from the rear fuse panel. Result: Did not fix the issue
   I have entered rear brake service mode with my Autel scanner and went through the reset process for the rear brakes: Result: Did not fix
   Removed and inspected the switch in the center console for any liquid damage or corrosion on the plug (none noted)
   Re-coded back in the front drivers seat belt warning through bimmercode (one forum indicated coding out could possibly throw the auto hold fault) Result: Did not fix

   I have the following Fault codes from the Autel scanner:

   D3840A
   4809C1
   CD840A
   D3AC8D
   D356F5
   D35B00

   So short of taking it to the dealer or an Indy shop I thought I would put out here. I am sure I am not the only one who has encountered this issue. Any suggestions or solutions are greatly appreciated.

   Thanks

   Help us to help you, for without words these fault codes are just Alpha-Numeric, and mean nothing.

3. Correct. You may as well be speaking Latin. Always post the fault code numbers with the descriptions.

4. Also, switch failure is possible even without having had something spilled in it.

5. Here is the descriptions associated with the previously posted codes. Thanks for the help

   __________________________________________________ __________________________________________________ ________________________________

   D3840A: EMF: Powertrain CAN communication fault (intermittent)

   
   4809C1: DSC EMF Brake cannot be applied mechanically (Permanent) Though this fault shows, the brake does mechanically apply and hold the vehicle.
   CD840A: DME PT-CAN Communication Fault (Intermittent) D3AC8D: DSC Interface (Status Hydraulic Function 25D) Signal Invalid (Intermittent)
   D356F5: No Message (status Seat belt contact seat occupancy 275.6.8) receiver DSC transmitter ACSM (Intermittent)

   D35B00: No Message (Request hydraulic function 100.1.2) receiver DSC Transmitter EMF

   (Intermittent)

6. I would say the only code is the 4809C1 that would apply to your braking issue. So the first thing I would do is remove each caliper, to see if they are frozen, locked, or binding. Also inspect the connector for the electrical portion on the caliper, ensure it is clean and connected properly.

   Hello,
   have you ever found solution for this problem?
   I have same on my F10 520d LCI for last couple of days when I started from parking, one hour before everything was perfect.
   Problem started with parking brake and Auto hold error, continues with ABS, DSC, transmission, powertrain errors etc during the driving.
   I tried to change battery, inspected parking brake actuators on calipers, changed brake fluid, checked fuses, tested all possible components on the car by ISTA and nothing helps.
   Two days ago after all that attempts erros was gone and I drove about 80kms without problems but suddenly everything lights up on dashboard and nightmare continued.

   Dashboard goes crazy with multiple errors while driving but when standing still on traffic light errors dissapear and throws message «secure vechicle from rolling» like gearbox is in N but its in D.
   Voltage seems fine, battery is good, 12.1V after one day not driving, in driving voltage is 13.7 so alternator is working OK.

   Do someone have any idea what to try next?

   Errors:
   CF040A EGS: Powertrain CAN: Line fault/electrical fault
   E0840A Gear selector switch PT-CAN: Communication fault
   4809C1 DSC: EMF: brake cannot be applied mechanically
   CD840A DDE, PT-CAN: Communication fault

   + many more and anything is existend when car is parked.

8. Looks like to me you have a lot of CAN errors, which would tell me you have crossed or bad wiring in the car. I would have to say that it might be from an animal chewing on lines and is causing all this. So you will need to start with a good wiring diagram, and then follow the wires looking for the bad ones. Also bad connections can cause those errors too.

    My problem was: burned Engine Wiring Harness 12518514877 on section located next to the turbo (who design that ?!!! )
    Problem solved so all of you having this issue or similar start from checking that wires.

    Hello! Sorry for ressurecting old thread! I have the exact same problems and I know some wires have melted there, did you just re-isolate or change everything, and if so what was the cost?

17. If you get the car connected to ISTA (BMW’s diagnostic computer system), it will not only do a test plan for the code, it will show you exactly where every associated component lives, just by clicking on that component in the provided wiring diagram.

Подстава пришла откуда не ждали. Вернее ждали, но не так. 😀
Симптомы такие — открываешь машину, а она тебе с порога прям говорит, что ручника у тебя больше нет.

Думаешь, ну мало ли, глюк. Да он мне и не особо нужен! Заводишь машину и начинается музычка, приятная уху (на самом деле нет).

Ну разве что подушки не сработали и на этом спасибо.
В итоге машина, конечно, едет, но усилитель руля не работает (или работает очень слабо), скорость не показывает, да ещё снег второй день идёт и ехать, без ABS хотя бы, не очень комфортно.

В итоге, мозговой штурм, гугл и здравый смысл подсказали, что ручка комфортного доступа сожгла пред #2 на котором, по чистой случайности инженеров БНВ, висит ещё и блок DSC. Будучи инженером, очень хотелось бы поговорить с тем человеком, который это придумал.

Замена преда (5 ампер) и отключение двух передних ручек исправили ситуацию в корне. Ручки действительно снять не проблема. Спасибо БНВ, что винты в торцах двери! Иначе их бы снимали пачками. Винт в торце не бойтесь выкручивать до конца. Он не выпадет внутрь, если вы не будете вконце прикладывать излишнее усилие.
Машина уже ни на что не ругается, поехала как прежде. Теперь разыскиваю передние б/у ручки с комфортным доступом в цвете с небольшим пробегом, с номерами 51217231931 и 51217231934. Если не найду бу то, конечно, придется ставить новые. Просто цена в 18 рублей за ручку не радует как-то. Учитывая, что она не вечная 😌

Коды ошибок для тех, кто будет гуглить: 930AC1, 801C20, CD943F, CD9456, CD9451, CD94F0, CD94F1, CD94EE, CD94EF, CD94A8, CD9409, CD94C1, CD94CF, CF16C1, CF16D1, D017B7, D017AB, D0179F, D017C1, D01B4C, D0153D, D0196A, D01782, D01660, D01B3A, D015DC, D015BC, D01B63, D01A1B, D76C03, D76C02, D76C32, D75580, D75570, D75520, D75530, D91420, E0EC03, E11490, E12C1F, E58500 — посмотрите первым делом пред №2, в бардачке который.

OK, I could use some help. I finished replacing my water pump, radiator, thermostat, drive belt/pulley/tensioner, transmission pan/filter, and mechatronic sleeve on Monday. I took the car for a post-repair test drive and everything was great. I went out to drive the car to work this morning and it wouldn�t start. I had a bunch of error messages pop up on the dash and infotainment screen…transmission malfunction, brake system failure, etc. I put the car on the battery charger and tried again when I got home. The car started and moved, but the same errors showed up almost immediately. I scanned the car with my BimmerLink app and got this list of codes:

Lots of CAN errors, but where to start? I have ISTA+ if that helps instead of BimmerLink.

Also, during my repairs, the car slipped off the jack and I broke two of the 3 bolts that mount the EPS motor to the rack. I removed the motor, used an easy-out on the broken bolts, replaced the EPS motor, and did the steering wheel end stop teach procedure with ista to center the steering wheel. All of which worked perfectly during my test drive.

I was thinking it might be a bad battery but it�s only about 18 months old and seems to holding a charge.

Any ideas?
