Hello everyone,

CEL popped on my drive home and I pulled the following fault codes from Carly.

Fault Code: 002DED
Fault Explanation: CDKPMRUHV 0x2DED - power management,
closed-circuit protection

Fault Code: 002C85
Fault Explanation: CDKDYLSH2 0x2C85 - Lambda probe 2 after
catalyst dynamics

Fault Code: 006E83

RDC (ID 0x31C) invalid (transmitter RDC) Please feel free to FC hide
(Bosch software error) / PT-CAN: Signal ST IND FLTR message in STAT
RDC; ID invalid 0x31C; RDC transmitter --- (DSC: Tire Pressure Control:
interface)

Fault Code: 00A12A
Fault Explanation: :Overtemperature A12A

Fault Code: 009C54

Fault Code: 009FF1
Fault Explanation: :E60-Mue: LIN Communication failure (keypad
left)

Fault Code: 00A6F3
Fault Explanation: :Coding data CRC error

I know the 2DED is a power drain some where not letting the car sleep. The 2c85 is a post cat o2 sensor i believe. Just not sure which side. The 9c54/5 is the fresh air sensors. I recently put in new cabin filters. Do these need to be reset?

Could the battery drain be the root of all my fault codes?

Thanks for the help!

 

Go have your battery bad alternator checked out. Bad battery can cause multiple codes to pop up.

 

Does anyone know what the normal voltage should be for an 04 525i?

 

Went to Autozone and had the battery and alternator tested. Battery was good, just needs a recharge. Alternator tested good.

 

Question remains why and how did the battery get low? How old is the battery and how many miles on the car? What is the battery voltage at rest and with the engine running?

 

I would advise battery be charged and codes cleared. Then go from there. My battery on my car gets low all the time because I drive it only a couple of days out the month. It helps if you put it on a trickle charger at night. Short trips are not good for our batteries the car needs to be driven.

Post back any updates

 

 

So any updates..did you get this fixed and what was it..?

I too have "006E83" and "00A6F3"....

Cheers

 

Sorry for the late update.

Turns out my VR on the starter was starting to go out. I'd get voltage spikes around 15-16v. It would make my radio audio pop and cute audio when flooring it. Then i started to get "high battery drain" at random times. I'd charge the battery fully and a few days later of driving it would get the error. I bought this car 2 years ago and didn't know when that batter was last replaced. Ended up replacing it with a DuraLast AGM Platinum. About a few days after the new battery install, I got the "High Battery Drain" again. Did some more research and figured it has to be the IBS. Replaced IBS with a Hella from FCPEuro. Its been about 2 weeks and now errors. It was the IBS. I need to run iCarly again and see what fault codes I get now. I'll post up when i get them. Hopefully this helps someone with the same problems i had.
