Eps errors but wheel works EPS torque sensor (steering angle index): Index Faulty
Hello. On f15 have following problem:


Checked for any fault codes on car via ISTA D Rheingold and I have the following logged at recent mileages. Errors are active.

48239C EPS torque sensor (steering angle index): Index Faulty

D01B2A Interface EPS (actual position EPS 51.0.2): Signal invalid

They are clearly related but I have no lights on the dash when I start car and the steering feels fine. After 10-20 minutes, comes chasis stabilisation error but wheel works good. Turn off car, turn on and chasis error deletes itself.


Ateering rack is original fri. Factory. No codings and programmings. I reinitialised eps and it finished successfully but thise 2 errors are not deleting. Any sugestions?

Are you able to update eps to latest software with esys or ista? Also - is brown ground cable 100% OK?

Already replaced? Somewhere I read that this can be caused by bad ground cable and also harness to wheel speed senors have corrosions on that cars. Check both thing.

Calculate testplan and do what ista want.
You must raise front of car, and EPS turn steering wheel to end positions
