My 2010 X3’s dash board is showing the traction control icon, the air bag icon and a yellow brake icon. For a while these 3 warnings would come on while driving, then go out the next time I’d start it. Now they are on all of the time. I do not notice any drivability issues. The OBD2 code I get on my reader is P1017 which, I can’t find anywhere. The reader also reads”sensor plausibility VV1 bank 1”
Does anyone know what this means or what the code is referring to!
I did install a lowering kit and was wondering if it was a wheel or brake sensor issue?
Thanks

Read up on "triad" and rear-wheel speed sensor reluctor ring on here. There are plenty of threads. Could be either issue.

Also get a BMW code scanner instead of the generic ODB one to determine which it is.
