Hi guys hope you can help
I was asked to code an AUX socket into a 56 plate S4 Cabriolet (B7 chassis) with factory fitted RNS-e but no telephone. I am using fully registered VCDS version 10.6.4. (from Nige).
When I did a scan there were a few faults but the scan did not cover modules 37 and 56 although they were indicated as being there.( at least they were listed at the top of the scan )
When I went to access the modules individually I got the error message 'cannot connect to control module' This happened two or three times with both modules.
The car has mfsw and all equipment (radio/sat nav/mfsw) operates as expected without any error messages.
I presume that modules 37 and 56 must be there otherwise the RNS-e wouldn't work - would it ?
My question is - am I not doing something correctly or is there a problem with the canbus wiring ?
Any help is much appreciated. (I have the scan but can't seem to post it !!! )
