Dear z4mconona,

Many thanks for your answer, I measured the battery voltage, 12.2 VDC. What surprises me that I do not have any battery related problems, the car starts and runns fine. I started to see this warning lights combination several months ago, first I had to drive 10-15 miles before the lights come on, now the lights are on all the time. Someone had the suggestion that the wheel revolution sensors, I checked them, mechanically they look good, electrically I do not know how to check them. Now I am on the hunt for good books/DVD whatever so I can read on the problem more. I have old Volvos, a 300D Mercedes, they are not as complicated as this Z4. And they are not as nice... How it goes, no such thing as a free lunch. I will check out the links to literature what you sent me, again many thanks zsazsa
