Hi there, i have a x3 that now shows warning lights on dash.

I ran the Bmw Skanner tool and found some errors:

I have had the the transfercase motor out and replaced the cog With the regulatorfix one. Checked the rear abs ring (looks ok), Visual inspection of the speed sensor (looks ok but think this is the culprit).

Im thinking the rear Wheel speed sensor or the abs ring must be the fault in not getting any speed on the speedo, but the codes it throws out..

Ignore the sunroof one (you know the casette right) and the Power window ones idk, they are all working.

Anyone encountered anything similar to this?

Also, when i had the transfer case open, the old cog was not bad in shape like seen on youtube and etc, but was thinking about the Electric motor itself, i tried to turn it when it was out and it made a loud clicking sound. It did not og around smooth like i would have thought.

I had the same warning lights. It turned out to be a rusty reluctor (abs) ring that was out of round. I had to replace the whole axel shaft.

Yes thats what i also have come to terms with, but there were some other stuff going on too. 3 out of 4 glowplugs were shot, when replaced, the glowplug box was faulty too so replaced that also. Then i went and replaced both rear abs sensors and everything was ok for a bit, all lights went off and drove all summer with no light, they appeared again now and stay on. Took out the abs sensors again and inspected them, and there is wear on the right sensor and it seems the reluctor ring is the problem. Tried cleaning is out with a flat screwdriver and alot of crc. But as you said its not round anymore from rusting..
