Short Circuit to ground

I need to solve this, please

Thanks in advance.

Online readings point to a faulty airbag control module. Especially since you don't have the pedestrian protection feature.
i.e the fault code is able to be generated by the general airbag control module even though the pistons/bumper/whatever don't exist.
Did you recently have any other work done?

I get a brand new new steering rack installed

I believe the pedestrian protection feature is referencing to the passenger seat sensor to engage/dis-engage the airbag for the passenger.

I believe the pedestrian protection feature is referencing to the passenger seat sensor to engage/dis-engage the airbag for the passenger.

Maybe but maybe not. What I'm reading is that Audi was concerned that a car might accelerate in an unintended fashion and try to run over a pedestrian. Therefore, a passive system was developed that would set off a pyrotechnic charge that would in turn extend pistons on either side of the hood and move it backward and upward a little bit, so as to move the hood away from the pedestrian. I saw a self study manual for the 2013 A3 that mentions this system, but I can't find a mention of it in the 2014 S6 manuals I downloaded from erWin (certainly could have missed it). Maybe the 2012 A6 does not have this feature, but when OP had work done on the car, some new component was added that is looking for this non-existent part. As gk1 wrote in post #2, it makes sense that such a system would be tied into the general occupant safety system. Hopefully smarter AZ members know about this and can help OP.

Have you tried clearing the fault and seeing if it returns? Maybe faults weren't cleared after adaptation of the steering rack.
