KGM servotronic

512 Views 3 Replies 2 Participants Last post by  scottalexander
Yesterday the check engine light went on and ISTA-D gave me code 0093BA (servotronic engine timeout).

Check out the ISTA screens below.

Did this happen because:

  • the servotronic motor broke in the steering rack?
  • the battery is low voltage and crazy things are happening?
  • something else?

Has anyone received this code in the past? What was the problem?

What is the KGM Servotronic? There is a Servotronic for Active Steering on the rack and pinion, but I think it goes thru a different module. You can also check you battery condition using ISTA, I forget where it is at, but its there. I'd check battery first, connectors next.

There are several sets of documents uploaded over here that discuss Active Steering that may be helpful. DSC and active front steering.
