2004 525. Active Steering fault light displays and won't go away. Problem is similar to other posts. My independent BMW mechanic replaced the battery, which had gone bad. He tried the steering post to post step to reset the Active Steering, but the light stays on. The car drives fine. He said he'd research the problem and I'll go back in a few days. I think he is aware that the next step could be expensive, and from what I read, it could be $4,000-5,000 to replace the Active Steering unit, wipe the computer and reload the software. My other option is to take it to a dealer in hopes they have found a simpler solution. Any ideas?

First you need to have EBCM - electronic brake control module check for DTC'S - diagnostic trouble code's . If the light is on there is a code stored . I think most part stores can do this and for free . After you find out what code is stored , looking up that code in service repair information for diagnostic trouble shooting chart would be next step . There are a few codes too.
DTC C0035 or C0040
DTC C0045 or C0050
DTC C0241 or P0856
DTC C0244 or P1689
DTC C0290 or C0292
Find the code do the diagnostic's , fix the problem , wiring issue's , a sensor , bad module ,what ever it is . The light will go out then . Here is a sample of code discription .
• DTC C0035 Left Front Wheel Speed Sensor Circuit
• DTC C0040 Right Front Wheel Speed Sensor Circuit
Too major for this forum - you probably should research the code online. It involves a pressure switch in the EBTCM ( electronic brake control model ) not reading the right voltage signal. It could be a wiring problem or a faulty sensor which could require having the EBTCM rebuilt. The active steering - traction control uses the brakes to keep the wheels from spinning or skidding.
If your check engine light is on then there is an active fault code in the computer that needs to be pulled in order to see what caused the light and how best to fix the problem. You can go to any major parts store and have the code[s] pulled for free. Write them down and post them for me to assist you further. You won't know the reason for the light until the code[s] are pulled and thus no diagnosis can begin until then.

Check your underhood fuseblock fuses.chances are the large 60 amp fuse for the power steering blew out.In the future I would stay away from jump starting and use a booster pack as these vehicles do not like voltage spikes.I have seen it cause module problems.
The check engine light comes on because the computer has detected a problem. You need to have the truck scanned for fault codes. Try going to Autozone or similar place to get the scan done. Once you have the codes, you can post them here for an expert to evaluate.
I had a similar problem with my 2002 Taurus. I removed the dash and pulled out the display behind the steering wheel. I reseated all the light bulbs behind the display. Everything has worked fine since. You will find more info on how to do this if you search the internet.
sir i am having problum in my town &country air bag light how can i turn it off manually
with out scan tool
kindly send me the answer on my email if possible
after replacing the battery, battery replacement has to be registered in the power module.Newer bmw's can experience battery draw issues. usually after battery replacment the active steering has to be re-aligned. you can try turning the steering wheel lock to lock to see if that solves your problem (usually only works on older cars) if you can find a shop that has a GT1 (bmw's older diagnostic equipment) they should be able to reset the light. At the same time if the vehicle has a battery draw and the power module is disconnecting the battery when the charge level gets low,that is your root problem and you will end up with an active steering fault over and over
