OK so I got my Tiguan Highline 2 months ago and have the VCDS cables and software from Ross Tech as I thought it would be fun to try and change some of the coding and get some additional functionality or at least to change some of the characteristics of the car. So I decided to start on something simple and activate the Traffic TMC as this seemed to be one of he easiest changes to make. So I tested the software with the cable to confirm it was a CAN bus and all reported good, tick, I did the full auto scan and apart from a few errors that seemed to be timing errors (some sensors not responding in time), all good. Then I went into controller 5F as per the instructions on this site, and thats where is all started to go wrong. It reported that the .ROD file was missing for EU_MUVgi4CGEN2HBAS 001001 (VW37) is missing. I thought this was due to the version of the software or the car was too new, so onto the Ross Tech site, downloaded the lates beta 17.8, and still no luck :( so what am I doing wrong? Why is the .ROD file still missing ? Can I make the changes without the .ROD file?
Thanks in advance for all your assistance, you all seem to have completely nailed this !!
