Hi, Nice to have found the forum.
I need some help with a couple of errors im getting on my e61 2008.
they are
4C18 MESSAGE ERROR (TERMINAL 15 0x130) DDE RECEIVER, CAS TRANSMITTER.
9CC5 NO MESSAGE LIN (RLS)
E714 message KCAN POWER MANAGMENT BATTERY VOLTAGE 3BE)
4A27 BSD INTELIGENT BATTERY SENSOR MISSING.

As for the 4A27, the sensor was not connected after i put a new battery on 2 days ago. Connected again.
Cant seem to find much information on the others other than 9CC5 which i think could be related to the lights module.
BMW fault code lookup doesnt give any other info than what my error code states.
I have a brand new battery on.
Ive checked alternator voltage and when car is running it is showing 15+ volts and even with lights and heater on its still showing 15+ volts so i guess that is ok.
Can anyone give me any help with any of these codes please.

Alternator seems to have a shot regulator. You may need to replace the IBS first, and then register the new battery.

Thank for the reply. The IBS is no longer showing a fault since i re-connected the lead. I gather you say that about the alternator due to the voltage being so high when the car is running? It did seem a bit steep to me.

What problem is being exhibited that caused you to read the codes?

TOMMY2704

only brought the car on the 6th and it coughed a bit on startup the next day so i checked the battery voltage. it was 11.8 so i decided to buy a new battery.
Did a voltage check with car off and running after changing and initially it was showing 12.3 volts and 14 volts but checked again a couple of days later and it showed 15.5 when running.
decided to read the codes and this is what i got, along with a couple of others that were just light bulbs.

But what problem(s) are you experiencing? E.g. Low battery discharge notification, car won't start, etc etc.

TOMMY2704

the car starts but with a little struggle after a couple of days and the battery voltage has gone down to 12.3/ 12.2 etc. checked for battery drain and doesnt seem to be one. after car sleeps it is virtually 0 volts. yesterday i got the yellow triangle with the explanation mark on ignition and 2 extra codes on obe being
3EED DDE power management close circuit current violation and
951B over voltage.
. its just the battery voltage and the warning codes above. ive ordered a new regulator.

donpb

Yes, please get that alternator voltage within spec (between 13.2 and 14.5 volts).

Are you able to register the battery?

TOMMY2704

I registered battery change via my OBD but not sure how to do it in NCS/INPA as when i looked it did not have my battery capacity in the options. Old battery was 80ah. new one is 100ah but NCS only had 110ah in options.

i have now changed the alternator and the regulator and it is still reading 15.3v when running. Any help please.
