I went for months with all the warning lights and same antics as everyone else. As I read thru alllllll the info hear I was going to start replacing likely items such as wheel sensors, dsc modules, etc. As I put off doing anything my problems progressed to trans failsafe and engine failsafe which almost stranded me in a construction zone with walls on both sides. The way the X acted was really ugly and I thought all the major drive train was toast.

Being a quick learner (ha) I was forced to take Weasels advice and limped to my dealer (after doing the battery discon to get going). Long story short the diagnosis told me the alternator overcharged to 18v (which is probably the max read) but was working fine now (huh), and an intake fault. That was it???? So, I had them change the alternator (reman) which I thought would be the first of many visits. Over 3000 miles now and running like new with NO warning lights. Only other repairs on the vehicle were cv axles done by indie.

By the by it's 2006 4.4 Sport Prem in Kalahari with 165000 miles. I do all normal maint, lubes, etc myself (thanks to this site) much more often than recommended. Yes, I changed the trans fluid twice and filter once using BMW SPEC fluid.

I'm very thankful for the guys who watch this forum and help others.
