Problem Child? Trifecta and then some
I just bought a 2003 X5 4.4i this week. It is a high miler(151k) with some issues. But I got it on the low knowing of a few ahead of time. It is very clean inside and out and I wanted something to run around town in so I can keep miles off my M3. I am a bit of a tinkering fool and hope to fix the issues with help from research and forums of course. That being said, This baby seems to have a lot of problems. I have already fixed the tailights. And found a leaking airbag. I order two new bags and they will be here Tuesday. I will R&R the bags myself. Seems pretty easy.
Now for the bad. It seems that I have the classic Trifecta of yellow DSC, ABS and Brake lights. Although sometimes the brake light is red. All coming on from start-up and remaining on. The steering is abit hard at times and the steering wheel does not tilt/tele nor does it make any noises like it is trying to move. Seats still function except memory. And the radio head unit buttons will not function. But if I put in a CD it will play fine and volume/skip controls on the steering wheel are working properly. Speedo and gauges function properly. I purchased this car and drove it two hours back home with the trans fail safe kicking in one time about an hour and a half into the trip. I pulled over, checked fluids and made sure it was not running hot. Then continued home without anymore problems.
I checked the battery which looks to be new and tested with a DMM at 12.56 volts with the car not running and 13.96 volts steady while running. I have an appointment with the Indy on Wednesday to scan the abs and check wheel sensors. My OBD2 scanner read one code(P0720) when I got home with the vehicle. I cleared the code and it has not returned 5 days later. Still no service engine light and car runs and shifts good. in auto or manual shift.
After filling you in on my situation. I guess what I want to know is. Is it possible that all the symptoms are coming from one issue, such as the alternator? Or does it sound like I have several issues to work through here? I tested the alternator and did not see any spikes. Is there a better way to test for spikes? Also, should I load test the battery? Thanks for any help:
