Fault Codes – Any insight appreciated
I just purchased a 2009 X5 E70 N62 from an auction. It appears to have some water damage from the rear sunroof drains / boots. The ABS / Brake / Traction / CEL and Steering Angle warnings are lit along with the electrical system malfunction in the central display. I have installed a new battery (92 AH) and have completely cleaned the rear fuse panel and all connectors on passenger’s side with contact cleaner, etc. I also cleaned the corroded contacts on the ATC 700 module but it maybe shot.
I have just scanned it with a Bavarian Technic Tool and got the following: Engine module for N62 Current Fault Codes 2DCF CAN, control panel: Signal error Error will cause a warning light Error is currently present 2BC1 Ambient temperature sensor, signal Error will cause a warning light Error is currently present 2F86 Error will cause a warning light Error is currently present 2DDB CAN, IHKA: Signal error Error will not cause a warning light Error is not currently present CDEB Error will not cause a warning light Error is currently present CDEE Error will not cause a warning light Error is currently present 2DDA CAN, CAS: Signal error Error will not cause a warning light Error is not currently present 2A1E Fuel level, signal Error will not cause a warning light Error is not currently present 2A21 Error will not cause a warning light Error is not currently present Gearbox control unit Current Fault Codes CF25 Message from SSFA: Seat occupancy buckles Error will not cause a warning light Error is not currently present CF35 Messages from CAS don't exist Error will not cause a warning light Error is currently present Gear lever Current Fault Codes E097 Message (dimming, 0x202) Error will not cause a warning light Error is not currently present E098 Message (LCD liquid crystal display light density, 0x2C0) Error will not cause a warning light Error is not currently present A83A Undervoltage Error will not cause a warning light Error is not currently present Test conditions have been completed Signal or value below threshold A83B Overvoltage Error will not cause a warning light Error is not currently present Test conditions have been completed Short circuit or signal interruption Dynamic stability control - 4 wheel Current Fault Codes 6EC4 DSC: steering-angle sensor, adjustment Error will cause a warning light Error is not currently present Test conditions have been completed D35C DSC: No message (instrument cluster 1B4) Error will cause a warning light Error is not currently present Test conditions have been completed 6F51 DSC: No message (EHC, 212) Error will cause a warning light Error is not currently present Test conditions have been completed D35E DSC: No message (temperature 310) Error will cause a warning light Error is not currently present Test conditions have been completed Timeout 5E8C DSC: No message (trailer, 2E4) Error will cause a warning light Error is not currently present Test conditions have been completed 5F49 DSC: Instrument cluster: interface Error will cause a warning light Error is not currently present Test conditions have been completed D360 DSC: No message (kilometre reading 330) Error will cause a warning light Error is not currently present Test conditions have been completed D35A DSC: No message (terminal status 130) Error will cause a warning light Error is not currently present Test conditions have been completed 5F56 DSC: Interface, Car Access System Error will cause a warning light Error is not currently present Test conditions have been completed D37D DSC: No message (FZD/RLS, 226) Error will cause a warning light Error is not currently present Test conditions have been completed Electro-mechanical parking brake Current Fault Codes D397 CAN TERMINAL STATUS 304 Error will not cause a warning light Error is not currently present Test conditions have been completed Active front steering for E70 Active roll stabilization E70 No Faults Found Tire pressure control module Current Fault Codes D107 Error: CAN bus off Error will not cause a warning light Error is not currently present Test conditions have been completed D13E Error: CAN telegram timeout at reception Error will not cause a warning light Error is not currently present Test conditions have been completed Transmission distribution module Current Fault Codes 53FD 53FD Clamp 30g voltage supply Error will not cause a warning light Error is not currently present Test conditions have been completed Short circuit or signal interruption 53FE 53FE Unexpected Reset Error will not cause a warning light Error is not currently present Test conditions have not been completed Signal or value below threshold 55C3 55C3 VGSG-all-wheel-Notlaufregelung activated.

Sounds like a flood car. What makes you think it was sunroof?
|
There are no signs of corrosion / water damage anywhere but the trunk, also Carfax was clean, no reported flood damage.
What codes lead you to believe it is a flood car? Would you happen to know what Can / Fault codes are thrown when the Transfer Case Module is bad? |
It's the cumulative list that gives the impression of a flood car. Clear everything and see what comes back. Will give you an idea of what relays, fuses, and modules are left to check. Much of your list is no longer present which can mean a few things. 1 your cleaning brought back a module/relay or two in terms of functionality. Or 2 those are historic codes than have been remedied at some point in the past.
I just went through this exact same thing with an E61. Started with something like 50 errors. Needed some relays and a module or two. Have it down to 1 error with the IHKA, but it's a "present" error which is related to something in the unit itself. Edit: BTW, there is no such thing as a cheap BMW. ;) Bought our wagon for $1200 and have about $2500 in it currently catching up on maintenance, missing parts, and general neglect from previous owners. |
reset or clear all codes. See what comes back.

Thanks for the feedback, the cleared codes are below.

Really looking forward to getting this X5 going, I have always adored this body style and will go over it with a fine tooth comb. Many of my other cars have needed tons of TLC as well, so I am prepared for whatever this one can throw my way. |
Sounds like you’re alternator is going bad. Undervoltage/overvoltage=bad alternator. Replace it and be happy. I had similar issues, it’s fixed after replacement. Also make sure you register the battery to the car with the right software. Hope it helps. $350 for new alternator plus labor around $120.

There are a ton of parts that- if they fail due to water damage- can in turn damage up- and down-stream components..
Like , IBS cable, Junction Box (JBE)... these cars have modules that hang on various busses, waiting for control signals and voltages to hit certain numbers. If the control is hosed, you can get these 'christmas tree' error reports. Check out your ground straps too. There is a reason this car showed up at auction..... I actually recall a doctor (MD) who bought a brand new X5 and brand new 535 from Sandy. Figured it would be a fun project. He didnt have a code reader; didnt have ISTA...didnt know how to read BMW schematics. Figured he would just take it all apart and clean contacts. If you ever need a neurosurgeon in NJ, I know someone you should NOT see.... |
I have read many posts and appreciate this forum immensely, but just realized that I have never updated this post. While some cars on auction are a basket case, some are not. I cleaned up the fuse panel in the trunk (with contact cleaner, lol), repaired the faulty CAN wiring splice underneath which seems to be common, replaced the battery and fried radio components with used parts (PL6 / ULFMULF2 / Telematics Module and DLP Module), changed all the fluids/filters and have been driving it ever since. I adore my E70 and am so glad I took a gamble on it. Best 5K ever spent.

I found this article online that points to some common areas where some KCAN wires may short. Was one of these areas the locations of your wire shorting problem? https://www.underhoodservice.com/bmw...ous-locations/ |

Just saw this. Congrats As the post above says..>WHERE was the CAN bus damage? How did you ID this, was it a damaged factory splice or someone else spliced it?? |
Quote:
CAN faults near the steering column, center console, front passenger seat rail, passenger foot well and front sub woofers are common but that was not my issue. I will check those areas eventually but I recommend checking the faulty dealer splice as it cleared up the most serious faults that I experienced. If memory serves there is a post here that addresses that very issue. Best of luck and keep us posted. |

Dealership is still looking at my X5 trying to root cause the KCAN faults. I chose to take the car to the dealership instead of an indy because the FRM module was replaced under warranty in Feb so I was hoping that maybe the tech screwed up on the install or maybe that there was some wiring harness fault covered under warranty or something.
So far no luck. The foreman has been investigating various suspect areas (supposedly per BMW engineering's recommendation) and hasn't found anything yet. He checked under the rear fuse box, but didn't find anything odd. He's also been checking each of the relevant KCAN modules and no issues found with the modules yet. Last update I got was that the foreman had removed one of the seats and was checking the wiring underneath, but found nothing that looked wrong. These KCAN faults (persistent faults are D904, E5C4, D2C4, DE84) have been around for a while and seemed to be benign, but only in recent months did they start causing odd behaviors like christmas light dash and turn signals/dome lights not working. But it's intermittent and the next day the car will be fine. Was hoping replacing the FRM was the root cause as symptoms pointed to FRM failure, but clearly it wasn't (although it was deemed the FRM had gone bad so good it was replaced under warranty). I've been forwarding any info I can find online regarding E70 KCAN faults to the dealership. Very annoying. |
Dealership got back to me and they finally found the problem. It was indeed the splice in the rear right quarter panel. They said that the wiring in the splice became disconnected so it was an open circuit. They re-soldered the wiring and then the KCAN faults disappeared.
Looks like it was the same root cause as the OP - splice underneath the fuse box in the rear right quarter panel. Trying to get the work covered under a TSB/SIB or something, hopefully. OP - Do you know if there was some TSB/SIB for this particular splice? |

So glad you were able to sort it out and time to enjoy the X5 now without frustration. :thumbup: |
Foreman told me that the splice below the rear quarter fuse box is common to all E70s. No TSB/SIB for this area, but I agree that there should be!!
Unfortunately, I discovered a new issue after picking up the X5 yesterday. It is indeed KCAN fault free now (finally!), but I found one persistent fault code complaining about Seat Control when I read out the code with Carly. 9ED7 - Error normalization SLV No errors on the dash or iDrive. However, I discovered that when I tried adjusting the seat position for the front passenger seat then things started going south. Once I started adjusting the seat position the iDrive complained about a Seat Position Malfunction. Seat Position Seat position not detected for proper restraint system operation. Have the system checked by the nearest BMW center. And then a few more codes pop up when I read out via OBD: 9EA8 - No hall pulses SLV / SMBF no hall pulses SLV 9EAA - No hall pulses LBV / No hall pulses LNV / SMBF no hall pulses LNV 9ED7 - Error normalization SLV If I clear the faults and then don't try adjusting the passenger seat position, then iDrive doesn't complain and there's only the 9ED7 persistent fault. The moment I try adjusting the passenger seat position the same problem occurs. I'm wondering if the dealership didn't properly connect back something when they put my car back together. I know they took out seats and everything in order to inspect all of the wiring harness to look for open/shorts. Gonna have a chat with them today. So close to being able to enjoy the X5 error free, yet so far...I bought this car for my wife and she's getting annoyed it's always in the shop. |

Double checked with my Carly while at the dealership and played around with the seats, lights, etc. and sure enough no faults! FINALLY fault code free! |
Where is this "dealer splice"? Is it visible simply by removing the rear compartment cover, or is it down below the plastic tray, or behind the fuse box? Was just hoping for some clarification to help me find the potential issue.
I, too, am chasing a bunch of persistent K-CAN errors. They don't seem to cause any noticeable symptoms, other than I'm hoping it will solve my occasional Comfort Access glitches. Appreciate anyone who can clarify where to look for this "splice". AM. |

Well, I figured it out. The K-CAN bus wires (in my case - 4) are spliced (soldered) together under the factory wire wrap as part of the main wiring loom at the bottom of the right rear cavity directly below the rear fuse box.
The K-CAN bus uses two wires - one green, the other green/orange. For some reason, my green wires were totally corroded, but my green/orange wires seemed fine. I still re-soldered the green/orange for good measure. Afterward, I hooked up ISTA, cleared the codes, and this was the glorious sight upon re-running the vehicle test. Yay!!!! Attachment 82461 I found a reference to connectors X15005 and X15006, so I searched for those and found this clue: Attachment 82453 Seemed like a longshot, but I went ahead and unwound all the tape on the main harness. Lo and behold.... I found this suspicious situation notice the loose green wires: Attachment 82462 A closer shot: Attachment 82463 Here's the "connector" cut open to reveal all the corrosion. It's not really a connector, it's just a plastic tube to cover up the soldered wire ends: Attachment 82464 Here's the green wires re-soldered and the green/orange before being re-soldered and able to re-use the plastic tube. I used a new piece of generic tubing over the green wires. I would have shrink wrapped, but I got tired of hunting for shrink wrap tubing in my garage. It'll show up next time I'm out there ;) Attachment 82465 Here's what the good green/orange wires looked like after removing the plastic tubing. Seemed perfect, though I re-soldered to be sure: Attachment 82466 Hope this helps someone else out there with persistent K-CAN line errors. These do not throw a CE light, but they show up anytime you run a scan with ISTA or other software. Though all the systems functioned, I did get some weird random flakiness from my Comfort Access system and a few other weird, but very sporadic problems. I'll report back in a few weeks to say if it seems those issues are gone. AM. |
I was helping a friend with similar CAN errors on his 08 E70 4.8 and this was indeed the issue/fix for those CAN errors. What great information! Priceless!

Nice! Glad it was of help!
AM. |
Looks like the ends of those splices were marinating in a water bath for a few years...finally failed due to the corrosion.
Off Topic... My in-the-ground dog fence failed after many years....seems gophers will come along and chomp into the insulation, but when they hit the copper wire it is YUCK!...they dont eat it or chew on the copper. BUT, the hole in the insulation allowed water to get in, and every spot failed with a green mass of mushy copper... as a result I had open wires every 20, 30 feet. Over 2500 ft of wire. Just replaced it. |
Does anyone have the wiring diagram showing those four green wires are indeed spliced together? My ‘13 e70 they are completely free with no copper showing almost like they were snipped. I get KCAN issues /Christmas tree only when it rains.
|
I looked, cannot find anything specific.
Just clean it up, strip some clean wire and wire-nut them...see if that fixes it. |
I did just as you suggested this morning :thumbup:
So far no codes, will see what the next torrential rain storm brings |
