Audi Repair Questions? Ask a Mechanic for Answers ASAP
My name is ***** ***** I am a professional here at Just Answer. I noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
In allot of cases I find this type of fault here can be caused by a weak battery itself or an issue with loose or corroded battery cables needing repaired or replaced.I have also seen issues with the electronic ignition switch as the cause as well needing replaced.If these have not been checked into at all this should be done to see if any of these are the cause here needing corrected.
O.k.,if they haven't checked to see if they can communicate with all computers with their scan tool/computer plugged into your vehicle this should be done.In some cases they can check and see if a control module isn't communicating and this can be the control module at fault causing a data fault between the computers causing this issue here.Usually this is the control module needing replaced.
The other option they can do is to contact their tech support as sometimes their tech support will have info on similar cases they have logged on file that may be causing this issue that can help diagnose this fault as well.
I apologize for the delay.
