5142 No message, receiver EGS, transmitter KOMBI

[xdk]

Hello, I kindly ask for an explanation of the error:

5142 No message, receiver EGS, transmitter KOMBI

E53 X5 3.0d 2005 freshly regenerated ZF gearbox, read error when receiving the car from mechanic,
this error showed up after scanning when the engine worked a few minutes.
Mechanic delete this error, turn off the engine and he did again scan errors right after launch engine again, this error did not show this time.
Mechanic said its some module and maybe issue can be something with voltage drops when engine work a few minutes and it causes a communication error with this module. Thats what i understood what mechanic said.

I have 2 more errors where i dont understand what can be wrong:

BD IKE: Electronic braking-force distribution
7D LCM: Turn Indicator, front right, faulty

Very please for help.

regards

If the first error is no longer present then it's sorted.  Only worry if it comes back.  It might have been caused as the battery had been disconnected for the gearbox change.

The second error means the extra brake lights that activate under heavy emergency braking are not working.  Possible wiring or module fault.

The third error is a failed front right indicator bulb.  You need a new one.

Yeah right turn signal bulb is burnt, so this error is solved.

Second error - where is wiring or what module can be fault and where is this?

First error - now i can't check errors, i havent equipment so i must go for check to mechanic, but i remember before i left my E53 for gearbox regeneration mechanic checked errors and this strange error with KOMBI was already appeared. So i think it can come back.

Any ideas what can it be, what is this KOMBI trasmitter, is this serious fault, and how to solve this? I hope its not transmission fault.

EGS to KOMBI is basically for the indication of gear selection in dash.
Telling you at some point comma was lost between them.

I get that occasionally and is inevitably voltage derived!!
It doesn't affect the gearbox or other functions and usually is just an advisory.

Big thanks for this reply! This is balm to my heart.

U know something about this Electronic braking-force distribution - what is this said X5Sport, but what can be fault and where can be located wrong part?

Happy new year

I think it is a second position on the brake light switch which is a magnetic rather than physical switch.

Check the bulbs are present, both good and the wiring to the bulb holders is OK and that the contacts on the lamp units are clean.  There are known corrosion issues with the rear light clusters.  Have a careful look at the seals before you put them back in as you may end up with water leaking into the boot.  New seals are probably a good idea.

You may be able to check they work whilst parked by pressing extremely hard on the brake pedal to see if a second pair of brake lights come on.  They may flash.  The additional lights are just above the standard pair and are designed to alert traffic behind that you are doing an emergency stop by either brightening up the lights or flashing them..

If that doesn't work then all I can suggest is go with a friend to either a very quiet road, or a large car park and try an emergency stop so that the ABS kicks in too.  A car park is the safer option.

Ok I check this lights, but are u sure this error mean this emergency lights issue, not system which responsible for driving safety?

Electronic braking-force distribution (EBD) -  Shorten braking distance

error:
BD IKE: Electronic braking-force distribution

If the lights are OK then the module is detecting the pedal travel so the next step is to look at the brake module.  If the fault is still present then the system itself needs careful looking at.  The module's function is to provide additional braking under emergency conditions by applying extra pressure.

Other than this function fault, are the brakes working correctly?  Any sign of a 'spongy' pedal or a lot of movement before the brakes come on?  There should be very little movement before anything happens and the pedal should be firm.  If the pedal is spongy at all then you may have air in the system.

If the brakes have been incorrectly bled in the past and air has been allowed to get in then it can stop all or part of the ABS and master cylinder functions from working correctly.  If in any doubt the simplest option is the get the brakes bled by someone who has access to the correct software.  BMW will have it, and so may Bosch Autocentres.  The software will operate all of the control valves in the system in the correct sequence to ensure any air etc is properly purged.  There is no other way of doing this and if done incorrectly it can wreck either the ABS modulator unit or master cylinder.  You can bleed the brakes yourself, but not the ABS unit.
