So here is where we are now. The original problem car going into limp mode and then car would not start at all with purchase of new battery, this from the prior owner. Well I unplugged the abs and bought a new battery. Both original problems fixed. Presently I am getting that huge current draw, error codes p0741 and p1870. When accelerating from stop has trouble getting out of 1st and 2nd after that fine, the battery light will flick on and off randomly while driving. Check engine light is on. I have a hunch that alternator is bad which I have thought from the beginning but could be wrong. I will test as most of you suggested by taking that B+ off. My first worry is that transmission, I am assuming and hoping it is the TCC solenoid. If I can get the transmission working I will then move on to the current draw problem. Is this the right solenoid? https://www.amazon.com/ATP-JE-8-Auto...me=2002+BMW+X5
Once again Thanks a bunch and will keep you updated as things progress. I was so down and out about this but this board has made it exciting again!!! |
THANKS for the update. Quick, while the others are distracted, let's try to get things back on track here.
Short info is to not worry too much about anything with the transmission, etc. while you know you have electrical problems. If you do have a transmission problem, fixing it will not fix the electrical problem. But fixing the electrical problem might fix everything else.
I would do all of that without even shifting out of park. I would first figure out what the current draw is when the key is not even in.
Do you have a 3.0i or a V8?
Charging light indicates you are not charging, but that would not explain the high current draw directly, unless there is a problem in the alternator that is causing the draw. Pretty simple tests can be done before you replace more parts.
