91 318ic - After flushing the old brake fluid out with ATE Super Blue fluid last week, My Anti lock light came on. The light will be off when the car is cold, but, will light a minute or two after I get underway.

I don't believe Carsoft will detect or reset the condition on an E30. '

Anyone have a similar issue and how did you resolve it?

Thanks! :cool:

I have changed my fluid twice and have never had that issue. I wonder if I am not doing something right? I can't tell if the fluid is passing through the ABS system. I know the fluid comes out clean at the caliper though. So it must be going through. I do have an issue with my left rear caliper though. The fluid is very tough to get out on that side. I am installing some stainless steel lines soon and will let you know if I end up with the same issue.

I did my '90 325i with ABS no problems what so ever!

Check the sensors. Measure their impendance.
