X5 Christmas lights - A troubleshooting thread.
2 Attachment(s)
I'm starting this thread as a way to document what I am going through with my 2002 X5 3.0.
Background: I purchased an abandoned 2002 X5 for pretty cheap and was told it needed a new alternator. I changed the battery and a blown fuse and the car started up and has mostly been running fine (ABS light is on & a parasitic battery drain issue that I am troubleshooting) until... About a month ago I was going up a very steep incline and my transmission went into fail safe mode. When I pulled the codes using OBDFusion I felt like I had won the lottery, but in reverse - screenshots attached. In looking up the first error I found a thread indicating that this could be related to low fuel and would require a fuel filter replacement due to excess sediment in the fuel filter. I got a fuel filter and spent some time yesterday replacing it, but I don't think that this has resolved my issues entirely. Today I fired up INPA and pulled the error messages and I have a ton of errors from a bunch of variants that I am still going through and deciphering. In post 2 I will add the error memory report and in post 3 the shadow memory report. |

Did you clear all codes and see which ones came back? Being parked for a long time doesn't help. All emissions tests start fresh. A good tune up and maintenance would probably clear most codes.
|
Incline plus fuel starvation more likely siphon jet not filter. Was the fuel level close to 1/4 tank?
O₂ heater error: reset them by unplugging all that have the street m error and run a few minutes key off and do a second time then reset codes plug the O₂ back in. |
+1 for resetting all codes and checking again after a couple of drive cycles (if the car is driving at least).

I bet you have wiring damage from rodents while the X5 was sitting. Check the wiring harnesses and connectors related to each of those fault codes.
Pending/shadow codes can be ignored. They are signs that have not yet met the threashold for promotion to error codes. |

Last time I cleared the codes (via OBD) was in October when I put in a new battery and replaced the fuse: https://www.bimmerfest.com/threads/2...p0600.1458851/ I also got the car smogged at that time and was able to drive it for a few months without issue aside from the electrical drain. I have not cleared anything in INPA since getting the car. |

Also I am using the INPA setup that you recommended on E46fanatics. I am seeing a few script errors. Is there anything I need to add to my INPA setup E53 friendly? |
